Scrap Iron Shredder Equipment Structure Diagram
Haoxing Machinery's Scrap Iron Shredder is a dual-shaft shredding machine used for primary size reduction of ferrous scrap materials. It is suitable for processing light scrap iron, iron sheets, metal drums, paint buckets, color steel tiles, appliance shells, motorcycle frames, prepared car body parts and other recyclable ferrous scrap.
The machine uses two counter-rotating cutter shafts with intermeshing alloy cutter discs. During operation, the cutter discs grab, squeeze, shear and tear scrap iron materials into smaller loose pieces. The shredded material is easier for conveying, magnetic separation, sorting, storage, transportation or further crushing.
The scrap iron shredder consists of a feed hopper, cutter shafts, alloy cutter discs, frame, electric motors, gear reducers, discharge conveyor and electric control system. It can be used as a standalone machine or integrated with magnetic separators, scrap metal crushers, conveyors, eddy current separators, dust collectors and other supporting equipment.
The process is as follows:
Feeding:
Ferrous scrap is loaded into the feed hopper by conveyor, loader or manual feeding according to the site condition.
Dual-Shaft Shredding:
Inside the shredding chamber, two cutter shafts rotate in opposite directions at low speed and high torque. The alloy cutter discs grab and tear the material into smaller loose pieces.
Discharge:
The shredded ferrous material falls from the bottom of the shredding chamber and is conveyed to the next process by a discharge conveyor.
Magnetic Separation:
The shredded material can be conveyed to a magnetic separator. The magnetic separator separates ferrous materials from mixed material streams, while non-magnetic materials continue to the next sorting stage.
Downstream Processing:
According to the material condition and recycling requirement, the shredded material can be sent to a scrap metal crusher, sorting platform, baling system or complete recycling line for further processing.
The scrap iron shredder operates through low-speed, high-torque shearing and tearing. After scrap iron enters the feeding hopper, two counter-rotating cutter shafts pull the material into the shredding chamber.
During operation, the alloy cutter discs on the two shafts grab, squeeze, shear and tear the scrap iron into smaller, loose pieces. This process is suitable for reducing the volume of light ferrous scrap, iron sheets, metal drums, paint buckets, color steel tiles, appliance shells, motorcycle frames and other bulky or irregular iron materials.
The shredded material is discharged from the lower part of the machine and can be conveyed to a magnetic separator, scrap metal crusher, sorting platform or other downstream recycling equipment according to the production requirements.
The output size is affected by the cutter thickness, tooth shape, blade gap, shaft speed, feeding amount and material thickness. For materials requiring a smaller or more uniform output size, the shredded material can be sent to a downstream crusher for secondary processing.
When hard material enters the shredding chamber or an overload occurs, the control system can reverse the cutter shafts to release the material. This helps reduce blockages and protect the cutter shafts, cutter discs, reducers and drive system during continuous operation.
The feed hopper and housing are welded from Q235 steel plates and machined after welding. They are designed for feeding and processing scrap iron, metal sheets, drums and other recyclable ferrous materials.
The shredder uses two heavy-duty cutter shafts equipped with alloy cutter discs. The cutter discs are arranged alternately to grab, shear and tear scrap iron during operation.
The main shafts are made of high-strength steel and processed for heavy-duty shredding applications. They provide stable support for the cutter discs during low-speed and high-torque operation.
The bearing system adopts a sealed installation for convenient maintenance and replacement. The sealing structure helps reduce the entry of dust and metal debris into the bearing area.
The machine frame and housing are made of thick steel plates. The reinforced structure is suitable for the continuous shredding of scrap iron, metal drums, sheet metal and other ferrous scrap materials.
A complete scrap iron shredder production line can include:
List of materials that can be processed by a scrap metal shredder：
Low-speed and high-torque shredding: The scrap iron shredder uses two counter-rotating cutter shafts to shear and tear scrap iron materials at low speed and high torque. It is suitable for primary size reduction of bulky, loose and irregular ferrous scrap.
Large feed opening for bulky scrap iron: The machine can process light scrap iron, iron sheets, metal drums, paint buckets, color steel tiles, appliance shells, motorcycle frames and other ferrous scrap materials. Feeding size should be matched with the selected model and material condition.
Dual-shaft shearing structure: The dual-shaft design provides stable material grabbing and tearing force. The cutter discs pull materials into the shredding chamber and reduce them into smaller loose pieces for further conveying, sorting or crushing.
Heavy-duty frame and cutter system: The frame is welded with thick steel plates. Cutter shafts, cutter discs, bearing seats and reducers are designed for continuous scrap iron shredding work. Wear parts can be repaired or replaced according to actual use.
Automatic reverse protection: When hard or overloaded material appears, the control system can reverse the cutter shafts to release the material. This helps reduce blockage and protect key parts such as cutter discs, shafts, reducers and motors.
Suitable for magnetic separation: After shredding, the material can be conveyed to a magnetic separator or downstream sorting equipment. This helps separate ferrous materials from mixed material streams and prepares the shredded scrap for further recycling.
Flexible line configuration: The scrap iron shredder can be used as a standalone machine or connected with feeding conveyors, discharge conveyors, magnetic separators, scrap metal crushers, eddy current separators, dust collectors and other supporting equipment.
Customizable configuration: Feed hopper size, cutter thickness, motor power, reducer type, discharge height, conveyor layout and control system can be customized according to material type, capacity requirement and site layout.
