Schematic diagram of the structural composition of a twin shaft shredder
The twin shaft shredder is a low-speed and high-torque shredding machine used for primary size reduction of bulky and irregular materials. It uses two counter-rotating cutter shafts to grab, shear and tear materials into smaller loose pieces before further crushing, sorting, baling or transportation.
The machine adopts a heavy-duty frame, alloy cutter discs, hardened cutter shafts, reducers and bearing seats. Cutter thickness, tooth shape, shaft speed, feeding method and discharge method can be customized according to material type and output requirements.
The twin shaft shredder can be used for processing light scrap metal, aluminum profiles, color steel tiles, metal drums, paint buckets, appliance shells, plastic drums, waste tires, wooden pallets and mixed industrial waste. It can be used as a standalone machine or integrated with conveyors, magnetic separators, crushers, eddy current separators, dust collectors and other recycling equipment.
Materials suitable for the twin shaft shredder:
Metal materials:
Light scrap iron, color steel tiles, metal drums, paint buckets, iron sheets, steel wire ropes, light steel offcuts and mixed scrap metal.
Aluminum materials:
Aluminum profiles, aluminum alloy scrap, thermal break aluminum, cast aluminum parts, aluminum sheets and aluminum cans.
Packaging containers:
Plastic drums, steel drums, aluminum cans, beverage cans, packaging barrels and similar recyclable containers.
Waste household appliances:
Washing machine shells, refrigerator shells, air conditioner shells, appliance metal shells and plastic housings.
Plastics, rubber and wood:
Plastic pipes, plastic pallets, wooden pallets, waste tires, rubber materials and mixed industrial waste.
A twin shaft shredder is a low-speed and high-torque shredding machine used for primary size reduction of bulky, irregular and mixed recyclable materials. It mainly consists of two counter-rotating cutter shafts. Each shaft is equipped with multiple alloy cutter discs, and the cutter discs on the two shafts are arranged alternately with spacers.
After the material is fed into the hopper, it falls into the area between the two cutter shafts. The two shafts rotate toward each other, and the cutter discs grab, pull and press the material into the shredding chamber.
During operation, the material is repeatedly squeezed, sheared and torn by the cutter discs and spacers. Large materials such as metal drums, plastic drums, aluminum profiles, appliance shells, tires, wooden pallets and other bulky materials are gradually shredded into smaller strips or irregular pieces.
The output size is mainly affected by cutter thickness, tooth shape, blade gap, shaft speed, material type and feeding amount. If a screen or bottom grid is configured, it can help control the discharge size. For materials that require smaller or more uniform output, the shredded material can be sent to a downstream crusher, magnetic separator, eddy current separator or other recycling equipment for further processing.
When the shredder meets hard or overloaded material, the control system can reverse the cutter shafts to release the material and reduce overload. This helps protect the cutter shafts, blades, reducers and drive system during continuous operation.

Low-speed and high-torque shredding: The twin shaft shredder uses low-speed and high-torque shearing to grab, tear and loosen bulky materials. It is suitable for primary shredding, volume reduction and material pre-treatment before further crushing or sorting.
Suitable for different bulky materials: The machine can process various recyclable materials, including light scrap metal, aluminum profiles, metal drums, paint buckets, plastic drums, wood pallets, waste tires, appliance shells and mixed industrial waste. The cutter structure can be selected according to material type and output requirements.
Stable feeding and strong material grabbing: The counter-rotating cutter shafts can grab and pull bulky or irregular materials into the shredding chamber. This helps reduce manual pre-cutting for suitable materials and improves feeding continuity in recycling production lines.
Heavy-duty structure: The main frame is welded with thick steel plates. Cutter shafts, cutter discs, spacers, bearing seats and reducers are designed for continuous shredding work. The reinforced structure is suitable for long-term operation in recycling yards and industrial waste processing sites.
Customizable cutter configuration: Cutter thickness, tooth shape, blade arrangement and shaft speed can be customized according to material type and required output size. Wear parts can be repaired or replaced during maintenance.
Automatic reverse protection: When overload or hard material appears, the control system can reverse the cutter shafts to release the material. This function helps reduce blockage and protect the cutter shafts, reducers and drive system.
Easy integration with recycling lines: The twin shaft shredder can be used as a standalone machine or connected with feeding conveyors, discharge conveyors, magnetic separators, crushers, eddy current separators, dust collectors and other supporting equipment.
Suitable for primary shredding before secondary processing: The machine is often used as the first-stage shredding equipment before hammer crushing, magnetic separation, eddy current separation or manual sorting. It helps reduce bulky material size and prepares the material for the next recycling step.

The shredder reduces bulky scrap into smaller loose pieces, making the material easier for conveying, sorting, baling or further crushing.
Find common questions about scrap metal crushers, shredders, recycling lines, equipment selection, capacity configuration and operation requirements.
The SX1200 twin-shaft shredder can be customized in color and configuration. The price depends on motor power, cutter thickness, reducer brand, material type, and capacity requirements.
The maximum processable thickness depends on machine model, cutter thickness, motor power, and material hardness. For heavy materials such as wheel hubs or thick scrap, a suitable heavy-duty configuration should be selected.
A scrap aluminum crusher or thermal break aluminum recycling line is usually suitable. The final configuration should be customized according to site size, budget, material size, and expected output.
If a suitable reference site is available near your area, we can help arrange a visit. Please provide your location, material type, and capacity requirement.
The price depends on motor power, cutter thickness, reducer configuration, frame strength, and material type. Please provide the material and required output size for an accurate quotation.
Yes, but the model should be selected according to daily processing volume, feeding size, aluminum alloy thickness, and discharge requirements. Please provide the approximate amount of material you need to process per day.
Yes. Standard models are available for most applications, and customized twin-shaft shredders can also be designed for special materials, special feeding sizes, or specific output requirements.
Stop the machine immediately and use reverse rotation to release the stuck material. Do not insert hands into the chamber. After clearing the jam, check for oversized material, hard foreign objects, and cutter clearance.
Twin-shaft shredder blades are commonly made of alloy tool steel such as Cr12MoV, H13, or other wear-resistant materials. Replacement frequency depends on material hardness, working hours, blade material, and wear condition.
The price of an 800-type twin-shaft shredder depends on cutter thickness, motor power, reducer brand, frame design, and the material to be processed. Please confirm the material and capacity requirement before quotation.
