What Is A Metal Shredder?

Scrap metal must be processed to be effectively recycled and ready for reuse. Metal shredders are machines used to process a variety of metal scraps. Metal shredders are frequently used to reduce metal debris to a standard shape and size for sorting and additional processing in scrap yards and metal recycling operations. They provide long-lasting performance thanks to their robust design. Metal shredders make it possible so both ferrous and non-ferrous metals can be crushed before shipment to steel mills for recycling into new metal. Additionally, they make it possible to destroy metallic material for companies where necessary.

Features of Metal Shredder Equipment

Thick and heavy moving knives, high crushing efficiency, the tools are cast in alloy steel, and have a long service life.

1)The frame plate is thick, resistant to high torque and very strong

2)Microcomputer (PLC) automatic control, set start, stop, reverse and overload automatic reversal control function.

3)The equipment has the characteristics of low speed, high torque, low noise and dust to meet environmental standards.

4)Easy to adjust, low maintenance cost, economical and durable.

5)The thickness of the tool and the number of claws can be changed according to different materials.

Types of Metal Shredders

Single-Shaft Metal Shredders
Single-shaft metal shredders have a rotor and hydraulic ram used to press garbage and scrap against the rotor, which starts the cutting process. Pressure sensors allow the ram to travel backward and forwards, preventing jamming and overheating of the material. Large bulk materials can be broken down into particles as small as 10 mm using these shredders, which can be equipped with various screen sizes. All single-shaft metal shredders have a classifier screen that provide a user with variable measurement settings that output units can be sized at.

Double-Shaft Metal Shredders
The double-shaft metal shredder is a popular industrial shredder due to its low operating speed, high torque, and high throughput which can effectively treat a variety of materials. Industrial shredders with twin shafts may feature electric motors or hydraulic drives and can process various materials. Double-shaft metal shredders are especially useful for "volumetric reduction" of materials needed to reduce the space that would otherwise be occupied by waste materials. Even though industrial double-shaft metal shredders often lack a classifying grid, the unique design of the blades in these shredders and their control of production parameters provide them with size control of their output material. Industrial primary shredders result from cutting-edge technology that seeks to provide effective and adaptable equipment, and they are incredibly versatile and made for intensive operation. Depending on the material and final size desired, double-shaft industrial metal shredders can be fitted with various components, or may simply function with other shredder stages, to reduce a material to the desired size.

Three-Shaft Metal Shredders
Three-shaft metal shredders can be utilized independently or as a central component in specialized shredding lines. Based on the type of material processed, the three models (800-1000-1300mm) provide capacities between 1.5 and 3.5 tons per hour and come with a screen for separating the output material. The output sizes for the treated material range from 30x30mm to 50x50mm. A three-shaft metal shredder has a cutting system featuring tough rotor blades with a sweeper shaft. In addition, a three-shaft metal shredder’s cutter discs can be replaced individually, while also providing a pivotable screen basket in the middle and protective bulkhead seals for the shaft bearing. Three-shaft metal shredders are available with mechanical or hydraulic drive systems with automatic power-down and reverse capabilities.

Four-Shaft Metal Shredders
Four-shaft metal shredders have two drive rotors to push the scrap material onto their additional cutting rotors below. Separate gear motors propel these cutting rotors. These additional cutting rotors are used to pre-shred materials before size reduction or additional processing with a granulator. Four-shaft metal shredders are similar in size to twin-shaft shredders and are typically used for waste that cannot be processed by a twin shaft, such as cars. Due to the presence of replaceable classifying grids, industrial four-shaft metal shredders (both electric- and hydraulic-based) have been built for crushing various materials and for dimensional control of the output material. Four-shaft metal shredders are the outcome of a cutting-edge project that strives to build effective and adaptable devices. Industrial four-shaft metal shredders are incredibly versatile and made for intensive use. By using grids with anti-wear treatments and providing exclusive interchangeable shaft technology, four-shaft metal shredders have significantly decreased management expenses and maintenance interventions.

Horizontal and Vertical Hammer Mill Metal Shredders
Both horizontal and vertical hammer mill metal shredders function by repeatedly striking a feed material with heavy hammers that weigh between 250 pounds and 1,000 pounds and rotate at rates of 500 revolutions to 700 revolutions per minute (rpm) while being driven by motors of 2,000 horsepower to 10,000 horsepower. With a hammer mill metal shredder, material is fed into a steel drum that rotates quickly while being struck by hammers placed on a shaft, breaking the feed material into small pieces. Horizontal hammer mill shredders have hammers that strike horizontally, while vertical hammer mill shredders have their hammers striking vertically.
No matter the design, all hammer mill metal shredders function essentially the same. Huge hammers attached to a rotor are used in hammer mill metal shredders to shred vehicles and other massive metal gear. Hammer mill metal shredders have several outboard flywheels with electric or diesel motors armed with spin hammers. Large, powerful hammer mill metal shredders include rejecting doors and a manganese liner for ejecting materials that can't be crushed.

Working Principle of the Waste Metal Shredder

The waste metal shredder is fed into the silo bin through the equipment of the loading conveyor. The material is evenly fed into the mainframe of the scrap metal crusher by the forced press roller extrusion and material handling system.

During the high-speed rotation of the spindle, the material is crushed by the primary impact by the blade, and the crushed material is smashed into spherical metal particles by high-speed hitting in the machine compartment through the roller press.

The scrap metal that reaches the discharge standard under the repeated impact is discharged out of the machine compartment through the bottom screen, and the discharged finished raw materials are sent to the sorting system through the discharge conveyance to waste impurities, scrap iron, scrap copper in the scrap metal, The waste is sorted to obtain high-quality raw materials for recycling and metallurgical processing.

The scrap metal crusher uses the kinetic energy generated by the high-speed rotation of the blade to crush the scrap steel. In the crushing, the surface dirt such as rust and paint on the scrap steel surface can be peeled off, and then under the action of the magnetic separation equipment, a certain block size can be obtained.

The Benefits of Shredder Machines To Meet Sustainability Goals

Shredder machines offer a range of benefits for various industries, making them an essential tool for waste reduction, recycling, and data security. Here are some of the main benefits of shredder machines:

Efficient Waste Reduction
Shredder machines can reduce the volume of materials, such as paper, plastic, and metal, making them easier to handle and transport. This can result in significant cost savings for waste management and recycling operations.

Improved Recycling Rates
Shredder machines can help to increase recycling rates by preparing materials for further processing. Shredded materials are easier to sort and separate, which can lead to a higher quality of recycled materials.

Increased Security
Shredder machines are commonly used to destroy confidential documents and other sensitive materials. This can help to prevent identity theft and protect confidential information.

Versatility
Shredder machines can process a wide range of materials, including paper, plastic, metal, and wood, making them versatile tools for various industries.

Environmental Benefits
By reducing the volume of materials and increasing recycling rates, shredder machines can have a positive impact on the environment by reducing waste and conserving resources.

Cost-Effective
Shredder machines are generally cost-effective to operate, especially in large-scale operations. The cost savings from reduced waste volumes and improved recycling rates can also make them a worthwhile investment.

Shredder Wear Parts

Shredder wear parts are components of shredding machines that are subject to wear and tear during the shredding process. As materials are shredded, the wear parts come into direct contact with the materials and undergo significant stress and abrasion. These wear parts need to be regularly inspected, maintained, and replaced to ensure the shredder's optimal performance. Here are some common types of shredder wear parts:

Shredder Blades/Knives
Shredder blades or knives are the primary wear parts of a shredding machine. They are responsible for cutting and shearing the materials into smaller pieces. The blades/knives can wear down over time due to the abrasive nature of the materials being shredded. Regular inspection and sharpening or replacement of blades are essential to maintain the shredder's efficiency.

Counter Knives
Counter knives work in conjunction with the shredder blades. They are positioned opposite the rotating blades and help control the cutting process by providing support and resistance. Counter knives also experience wear and may need to be adjusted or replaced to maintain proper cutting efficiency.

Screens/Grates
Shredders often have screens or grates installed in the discharge area to control the size of the shredded material. These screens or grates can wear down or become clogged over time, affecting the shredder's performance. Regular inspection, cleaning, and replacement of screens may be necessary to ensure consistent output size.

Rotor Shafts
Rotor shafts are critical components that rotate the shredder blades. Over time, the constant rotation and stress can cause wear and fatigue on the shafts. Regular inspection and maintenance, such as lubrication and alignment, can help prolong the lifespan of the rotor shafts.

Hammers
In certain types of shredders, such as hammer mills, hammers are used to impact and break down the materials. These hammers can wear down or break due to the repetitive impact. Regular inspection and replacement of worn or damaged hammers are necessary to maintain the shredder's efficiency.

Wear Plates/Liners
Shredders may have wear plates or liners installed in high-wear areas, such as the shredding chamber or housing. These plates provide additional protection against abrasion and prolong the lifespan of the shredder. Regular inspection and replacement of worn or damaged wear plates are necessary to maintain the shredder's performance.

Maintenance Best Practices for Waste Shredders

Plan for Downtime
It is imperative for shredders to be maintained regularly, especially within the waste industry, where a variety of materials is introduced into the shredder and processed at once. The best thing you can do for your operation to prevent large chunks of downtime is to routinely and thoroughly clean and maintain the shredding chamber. Rotating knives and replacing counter knives regularly is important to keeping the cutters sharp and performing optimally. One severely damaged knife can shut down a whole system if not dealt with proactively. Checking belts for wear and replacing them if necessary can also prevent any unwelcome surprises while the shredder is in operation.

Safety is Key
When preparing to access the cutting chamber on your shredding machine, lock-out/tag-out procedures should always be followed. Every shredder comes with access doors to the shredding chamber, making it easier to change screens, rotate or change knives and clean the rotor. With safety in mind, a safety switch prevents the machine from being turned on while the door is open. It is designed to protect personnel while they perform crucial preventative maintenance tasks, like knife rotation/replacement and basic clearing of any debris.

Metal Detection as Prevention
One of the best ways to prevent the introduction of foreign objects into your shredder is to install a metal detector along the shredder’s infeed conveyor. This can be an operation’s last chance to remove any metal pieces that may have gotten through the pre-sorting process. This is a small piece of technology that can make a huge difference in plant productivity due to decreased incidental down time. Prevention is the best cure.1 A lot of unnecessary downtime is required to remove harmful foreign objects and/or repair any damage those objects have caused within your machine; installing a metal detector that can prevent the introduction of those harmful materials in the first place is a much smarter approach.

Keep Operations Running
Regularly performing preventative maintenance on your machine will lessen the chances for an unexpected issue. Moreover, anticipating problems before they happen allows you to implement measures into your waste-to-energy line that will keep your operation running smoothly and your shredder running.

How to Choose an Industrial Shredder?

An industrial shredder (shredding machine) is a major size reduction machine for the recycling business. Its versatility and heavy duty make it a reliable machine to break down bulky waste like furniture, scrap vehicles, and baled water bottles. There are at least 3 types of industrial shredders available in the market. The price of the shredder varies based on functionality and capacity. These instructions introduce how to select an industrial shredder for a recycling plant owner and people who intend to buy a shredder.

Understand Your Need
Just like buying a paper shredder, you know you will mainly process paper. Similarly, understanding what materials you will put into the shredder is the first step. Paper, scrap metals, wood waste, large plastic lumps, and municipal waste are the common infeed materials for an industrial shredder.
The more non-homogeneous the materials are, the more complex the industrial shredder is.
Try to match one single material to one shredder. This eases the model selection and maintenance later on.

Make Sure the Shredder Can Finish the Job
An industrial shredder has at least 2 blade configurations: single shaft and multiple shafts (cross-cut). The blade configuration determines the shredding efficiency and effectiveness. Consult the machine suppliers for better advice. As a rule of thumb, use double shaft shredder for non-homogeneous and hollow materials (e.g. mattress, electronic waste, mixed waste, and municipal waste); use single shaft shredder for homogeneous and rigid materials (plastic rejects and wood waste). Always consult machine suppliers for pros and cons for using each type of shredder.

Set a Capacity and Budget
Simply put, this is how much you want to shred in a given time, usually measured in kg/hr or ton/day. The capacity greatly affects the machine price and model. [6] Screen opening (output size) and collection method also play a role in determining capacity. The final size around 20mm is ideal for incineration and 10-12mm is ideal for plastic palletizing.
Make sure your selected machine stays within your budget. Otherwise, downsize or upsize your machine models.
The smaller the output size, the lower the capacity, as the machine takes a long time to break down the materials.

Add Auxiliary Equipment
For recycling business, adding automated equipment such as a belt conveyor, metal detector, granulator, and wash tanks significantly increases your productivity and the product value.
Confirm how to feed infeed materials and how to collect final materials. Add a metal separator to remove harmful metals to increases the service life of the industrial shredder.

Frequently Asked Questions about Metal Shredder

Q: What is a scrap metal shredde?

A: A scrap metal shredder, also sometimes referred to as a metal scrap shredder, is a machine used for reducing the size of scrap metal. Scrap metal shredders come in many different variations and sizes.

Q: What is a metal shredder used for?

Q: How do scrap metal shredders work?

A: Scrap metal shredders are used to reduce the size of scrap metal into manageable, transportable pieces. They come in various sizes, from small machines capable of shredding tin cans and coins to huge models that can operate at 10,000 horsepower and shred up to 4,000 tons of metal a day. These larger machines shred items like automobiles as part of the end of life vehicle recycling process, bulk drums and virtually every other type of scrap metal.
Shredders can have different styles of cutting systems, including horizontal or vertical shafts, single-shaft, double-shaft or even three or four-shaft cutting systems. Shafts can be manufactured with different styles of blade, which usually feature claws of varying thickness, depending on the material that needs to be shredded. Alongside the number of shafts, shredders can be high, medium and slow speed systems – typically, the kinds of shredder used in scrap metal recycling are of the slow-speed, high-torque variety, allowing them to chew through huge pieces of metal effectively.
On an industrial scale, large pieces of scrap metal – like crushed, old cars, for example – are fed into the shredder, moving through the feeder pipe to the shredding section, where heavy-duty hammers spin and break down the metal. The shredded material is separated into ferrous and non-ferrous material using magnets before being carried along conveyor belts and eventually being spewed out of the other side of the machine into two separate piles for further sorting.

Q: What is a metal shredder called?

A: A modern metal shredder (sometimes called a “crusher”) turns large-sized pieces of metal into smaller pieces, reducing the overall volume. Metal shredders can operate as stand-alone solutions.

Q: How is a metal shredder different from a metal briquetting machine?

A: A metal briquetting machine takes shavings, filings, or metal scrap and compresses them into dense, high-quality bricks that can be reused or sold. The raw materials for the briquetting process could come directly from a production process or from a metal shredder.
Like metal shredders, briquetters can be integrated into an existing production process easily.
The demand for metal briquetting is growing—and because of that, we’re getting more questions about metal shredding machines, too.

Q: Do you need a briquetting machine if you have a metal shredding machine?

A: Shredders can reduce the volume of material, but they can’t help you squeeze value from it. Metal shredders certainly make waste removal easier, because there’s less of it to dispose of. But briquetting is where you can see significant value.
Compressing shredded metal into a high-quality briquette suddenly makes it appealing to scrap dealers. Briquettes are sellable, easy to manage, and best of all, they funnel money back into your operations. A shredder alone can’t achieve this kind of quality and value.

Q: What is an industrial shredder?

A: An industrial shredder is a machine used to break down materials for various applications such as recycling, volume reduction, and product destruction. Industrial shredders come in many different sizes and design variations based on what particle size is needed for the final shredded product.

Q: Which kind material can be used in metal shredder?

A: Metal shredders are divided into double-shaft metal shredders and single-shaft metal shredders. The main function of metal shredders is to shred large pieces of metal materials and large-diameter drum metal materials that are inconvenient to transport. The shears of the machine extrude each other and shred them into flakes that meet the requirements. Large-scale metal shredders not only improve production capacity and crushing efficiency, but also expand the scope of application.
The metal shredder can mainly shred hard metal materials such as color steel tiles, oil drums, paint drums, car shells, motorcycle engine shells, automobile oil filter elements, etc. The metal shredder can also shred car tires, large PE pipes Shredding and shredding processing is a multi-functional metal shredding and shredding machine.

Q: Why is metal shredding central to recycling?

A: Metal shredding serves as a key element of the metal recycling process, providing the foundation for numerous subsequent stages that transform scrap into reusable materials.
By effectively fragmenting scrap metal into smaller parts, shredding represents a catalyst, facilitating more efficient operations, such as material separation, reducing waste, and preparing the metal for its future use. Let’s explore the main reasons why shredding forms an integral part of our commitment to a more productive and sustainable metal recycling process.

Q: What are the benefits of a metal shredder?

A: Metal shredders offer several benefits, including the ability to efficiently and effectively process large volumes of metal scrap, reduce waste and save on storage space, and recover valuable metals for recycling and reuse.

Q: Can shredder shred metal?

A: Yes, Alongside the number of shafts, shredders can be high, medium and slow speed systems – typically, the kinds of shredder used in scrap metal recycling are of the slow-speed, high-torque variety, allowing them to chew through huge pieces of metal effectively.

Q: What are the different types of scrap metal shredders?

A: Scrap metal shredders can be equipped with different types of cutting systems: horizontal shaft, vertical shaft, single-shaft, two-shaft, three-shaft and four-shaft cutting systems.

Q: What are metal shredder blades made of?

A: Steel, a ferrous alloy enriched with elements such as chromium, manganese, and nickel, is essential for imparting properties to the blades, such as impact resistance and wear resistance, as well as facilitating maintenance, such as re-sharpening and welding.

Q: Why use shredder oil?

A: Oil serves to soften this packed dust and counteract sticky residue build-up, which allows the proper movement of the cutting head and the paper through the cutter head. The proper movement of this head will push the dust and paper out of the paper shredder.

Q: Can paper shredders shred metal?

A: No. The blades of the paper shredder are also not intended to be used to cut through the metal. It could cause the shredder to jam or even permanently damage the machine. For these reasons, it is best to use paper shredding and disposal services.

Q: How strong are metal shredders?

A: They come in various sizes, from small machines capable of shredding tin cans and coins to huge models that can operate at 10,000 horsepower and shred up to 4,000 tons of metal a day.
