In industrial production, the double-shaft shredder is a commonly used equipment for the treatment of various solid wastes, such as plastic, rubber, wood, metal and so on. Although these machines are well designed, they are still subject to various failures. Understanding these common problems and their solutions is essential to ensure the proper operation of your equipment and extend its service life. ### 1 motor overheating ** Cause of failure: ** overload, poor heat dissipation or motor itself. ** Solution: ** Check whether the load is too large, clean the cooling system, and replace the motor if necessary. ### 2 bearing damage ** Cause of failure: ** insufficient lubrication, poor bearing quality or long running. ** Solution: ** Add lubricating oil regularly, select high quality bearings, and check them regularly. 3. Blade wear ** Failure cause: ** Long time use, material hardness is too high or blade material is not good. ** Solution: ** Replace the blade regularly and choose the blade material suitable for the hardness of the material. ### 4. Transmission system failure ** Cause of failure: ** gear wear, chain slack or coupling damage. ** Solution: ** Check and replace worn parts, adjust chain tension. 5. Material blockage ** Cause of failure: ** uneven feed, high material humidity or unreasonable equipment design. ** Solutions: ** Ensure uniform feed, control material moisture, and optimize equipment design. ### 6 Noise is too large ** Cause of failure: ** bearing damage, loose blade or improper installation. ** Solution: ** Replace bearing and tighten blade to ensure correct installation. ### 7. Electrical system failure ** Cause of failure: ** line aging, poor contact or electrical component damage. ** Solution: ** Check and replace aging wiring to ensure good contact and replace damaged electrical components. ### 8 hydraulic system leakage ** Cause of failure: ** seal aging or damage. ** Solution: ** Replace the seals and check the pressure and flow of the hydraulic system. ### # 9. Poor shredding effect ** Failure causes: ** The blade gap is too large, the blade is not sharp or the feed speed is not matched. ** Solution: ** Adjust the blade clearance, sharpen or replace the blade, optimize the feed speed. ### 10. Equipment inefficiency ** Cause of failure: ** Equipment aging, improper maintenance or improper operation. ** Solution: ** Maintain the equipment regularly and operate correctly according to the operation manual. To minimize failures and downtime, regular equipment maintenance and inspections are recommended. In addition, operators should receive appropriate training to ensure they understand how to properly operate and maintain the two-shaft shredder. Through these measures, the performance and production efficiency of the equipment can be ensured.
