A shredder is a machine used for rough crushing, usually used to process unprocessed raw materials or scraps to make their size smaller. Its principle is that the motor works and rotates, the reducer reduces the speed, increases the torque, and ultimately achieves the squeezing, shearing, and grinding of materials through the interaction between the knife rollers (dual axis shredder) or fixed blade moving knives (single axis shredder) to process them into smaller sizes.

As a large-scale mechanical equipment, shredders may encounter various problems during operation, such as equipment failure to start, machine jamming and automatic shutdown, abnormal vibration, severe tool wear, overheating of bearings, shredding of materials with debris, frequent shutdown of feeding devices, and so on. Below, we will list the most common problems with shredders in order and provide answers.

1、 The device cannot start
After the device is powered on, it starts up but still cannot start up properly.
Shredder blade roller
Reason 1: Material blockage
It may be due to excessive material filling in the shredding box, causing overload of the knife roller during operation, and it is necessary to clear the shredding box.
Reason 2: The motor safety switch is closed
Check the motor relay to confirm if the motor safety switch is in the closed state
Reason 3: Star angle startup error
Correct motor wiringThe dual axis plastic shredder is widely used, not only for crushing waste plastics, but also for crushing waste rubber, waste wood, waste fabrics, etc. It has broad application prospects in fields such as plastic recycling and resource reuse.

2、 Machine jamming or automatic shutdown
Reason 1: Screen stuck
Clean the sieve and replace it with a larger one if necessary
Shredder screen
Reason 2: Belt slipping
Remove the cover and check if the belt between the active and driven pulleys has slipped, and make appropriate adjustments
Reason 3: Tool issue
Check the sharpness and wear of the cutting tools, sharpen the blades or replace them
Shredder blade
Reason 3: Blocked discharge port
Check the operation of the discharge device and clean the blocked discharge port
Reason 4: Problems with the current itself
Check the limit switch, check the circuit connection, and if necessary, tighten the limit switch
Reason 5: Knife roller rotation direction
Check whether the rotation direction of the knife roller is forward or reverse. If it is reverse, reconnect to the zero fire position of the power plug and observe the rotation direction of the knife roller

3、 Overheating of bearings
bearing
Reason 1: Excessive lubricating oil in bearings
Open the bearing cover and inspect the bearing surface. If any excess lubricating oil is found, clean it thoroughly
Reason 2: Belt is too tight
Relax the belt appropriately
Reason 3: Sealing ring friction
Check or replace the sealing ring
Reason 4: Bearing damage
Check the bearings and replace them promptly if any damage is found
