1. What is a double-shaft shredder?
A double-shaft shredder (also known as a shearing shredder) is a shredding device that shears, squeezes, and tears materials by rotating two main shafts (moving shafts) with blades relative to each other. It is characterized by low speed and high torque, and is suitable for processing materials with high hardness and strong toughness, such as scrap metal, plastic, rubber, wood, electronic waste, etc.
2. In which industries are double-shaft shredders mainly used?
Solid waste treatment: volume reduction treatment of domestic waste and industrial waste.
Resource recycling: crushing and recycling of scrap metal, plastic, rubber, and tires.
Biomass treatment: crushing of wood, straw, and garden waste.
Special industries: harmless treatment of electronic waste (PCB boards), medical waste, and hazardous waste.
3. What preparations are needed before starting the machine?
Check the components: whether the blade gap is normal, whether the screws are loose, and whether the bearing lubrication is sufficient.
Test the direction of rotation: ensure that the two main shafts rotate in opposite directions (clockwise + counterclockwise) to avoid damage to the equipment due to running in the same direction.
No-load test run: start the machine and run it at idle for 5-10 minutes to observe whether there is any abnormal vibration or noise.
