Color Steel Tile Shredder Working Process
Material Inspection and Preparation
Color steel tile scrap should be inspected before feeding. Thick structural steel, sealed containers, batteries, pressure vessels and hazardous materials must be removed or handled separately.
Sandwich panels containing foam, rock wool, adhesive layers or other filling materials should be evaluated separately according to their construction and the required downstream process.
Controlled Feeding
Loose or prepared roofing sheets are loaded into the feed hopper by a conveyor, grapple, loader or another suitable material-handling device. The feeding method should match the sheet length, folded condition, bundle size and required capacity.
Long sheets should be fed in a controlled direction to reduce bridging and sudden accumulation above the shredding chamber.
Low-Speed Twin Shaft Shredding
Two gear reducers drive the cutter shafts to rotate toward each other at low speed and high torque. The cutter teeth grip and pull the steel sheets into the shredding chamber.
The material is repeatedly folded, squeezed, sheared and torn into shorter, looser pieces without relying on high-speed hammer impact.
Coarse Material Discharge
The processed sheets are discharged as coarse and irregular pieces. The output condition depends on cutter width, tooth design, cutter spacing, shaft speed, sheet thickness, material folding and the number of cutting passes.
A twin shaft shredder does not normally produce the same precise, screen-controlled output as a hammer crusher.
Optional Secondary Crushing
When smaller and more consistent output is required, the shredded sheet metal can be transferred to a scrap steel crusher for secondary hammer crushing and screen-controlled size reduction.
Optional Magnetic Separation
Magnetic separation may be used when the processed material contains iron or steel mixed with suitable non-magnetic residues. Clean color steel tile scrap may be collected directly without this stage.
Optional Light-Material Separation
When the incoming sheets contain protective film, foam, insulation or other lightweight attachments, airflow sorting or manual inspection may be added after suitable size reduction.
The required separation method depends on the type, amount and attachment condition of the non-metallic material.
Automatic Reverse Protection
When excessive resistance or a material jam is detected, the control system can stop and reverse the cutter shafts to help release the obstruction.
This function helps reduce prolonged overload on the cutters, shafts, reducers and motors, but it does not replace material inspection before feeding.
Material Collection
The shredded material can be collected directly, transferred to magnetic separation, sent to a baler or conveyed to a downstream crusher according to the required final result.
