What to do if a single-shaft shredder jams during operation

Emergency Stop and Safety Precautions

Immediately press the emergency stop button to cut off power and prevent secondary damage.
Wait until the cutter shaft has completely stopped rotating and the equipment is stationary before proceeding with further operations.
Operators must wear protective gloves, goggles, and other safety equipment.
It is strictly forbidden to reach in with hands or tools while the equipment is not completely stopped.
Prevents accidental pinching and serious injuries.
Simultaneously, set up warning signs around the equipment.
Prohibit unauthorized personnel from approaching the operating area during maintenance.

Carefully observe the feed inlet and shredding chamber to determine the type of jam.
If the material is too large or has excessive hardness, confirm whether it exceeds the equipment's processing range.
If foreign objects are mixed in, check for hard impurities such as metal or stones jamming the cutters.
If the material is being fed too quickly, verify whether the feeding rhythm matches the equipment's processing capacity.
Check for dulling or deformation of the cutters that may contribute to jamming.
Verify whether the cutter shaft rotates smoothly, ruling out jams caused by equipment malfunctions.
Identify the root cause of jamming before attempting to clear the material.

Select appropriate tools, such as long-handled hooks or pry bars, to assist in clearing.
Avoid direct contact with the blade edge to prevent injuries.
For large pieces of material, cut them into smaller sections before removal.
For foreign objects, carefully separate the blade from the entanglement or obstruction.
Avoid forced prying that could damage the blade or cutter shaft.
Remove the jammed material gradually during the clearing process.
Ensure no residue remains in the shredding chamber after clearing.
Check the condition of all components to confirm there is no looseness or damage.

After clearing, adjust the feeding rhythm to avoid excessive or rapid feeding.
Perform strict pre-treatment of the material before shredding.
Sort out hard foreign objects and crush large pieces of material to a suitable size.
Check the condition of the blades regularly, and grind or replace them if necessary.
Ensure cutting capability is maintained for optimal performance.
Strengthen inspections during subsequent operation.
Closely monitor changes in equipment load during operation.
Promptly adjust or stop the machine for inspection if signs of jamming appear.
Watch for symptoms such as a decrease in speed or abnormal noise.
Reduce the occurrence of jamming at its source through proactive measures.
