1、 Mechanical blockage

Fault phenomenonThe crusher cannot work normally, producing abnormal noise or vibration, and the material cannot be discharged smoothly.
Root cause analysis：

• PVC pipes with excessive size or irregular shape can cause materials to get stuck in the crushing chamber.
• The feeding speed of the crusher is too fast, resulting in excessive material accumulation.
  solution：
• Shutdown cleaningImmediately turn off the power, wait for all components to stop rotating, and use tools or manually clean the blocked material in the crushing chamber.
• Adjust the feedControl the feeding speed to ensure that the material enters the crushing chamber evenly and continuously, avoiding excessive material input at once.
• Pre processed materialsPre cut or crush PVC pipes that are oversized or irregularly shaped to meet the feeding requirements of the crusher.

2、 Transmission system malfunction

Fault phenomenonThe crusher is not running smoothly, with abnormal vibration or noise, and the temperature of the transmission components is too high.
Root cause analysis：

• Loose, worn, or broken components such as gears, belts, and chains in the transmission system.
• Insufficient tension of the belt or chain can cause slippage.
  solution：
• Check and tightenRegularly check the connection of transmission components to ensure that screws, bolts, and other fasteners are not loose.
• Replace worn partsReplace severely worn components such as gears, belts, chains, etc. to ensure the normal operation of the transmission system.
• Adjust the tensionAdjust the tension of the belt or chain according to the equipment requirements to avoid being too loose or too tight.

3、 Tool wear or breakage

Fault phenomenonThe crushing effect deteriorates, the material is crushed unevenly, and abnormal noise or vibration occurs.
Root cause analysis：

• The tool wears out severely after prolonged use, resulting in a decrease in its crushing ability.
• Mixing hard impurities (such as metal, stones, etc.) into the material can cause tool breakage.
  solution：
• Regularly inspect cutting toolsRegularly check the wear level of cutting tools based on production conditions and replace severely worn tools in a timely manner.
• Optimize material pre-processingClean and sort PVC pipes before crushing to remove hard impurities and reduce the risk of tool damage.
• Choose wear-resistant cutting toolsChoose tool materials with high hardness and wear resistance to extend the service life of the tools.

4、 Bearing malfunction

Fault phenomenonAbnormal noise or vibration occurs during the operation of the crusher, and the temperature of the bearing parts is too high.
Root cause analysis：

• Poor lubrication of bearings leads to increased friction.
• Impurities or moisture mixed into the bearing can cause corrosion or wear.
• Improper installation of bearings can result in excessive or insufficient clearance.
  solution：
• Regular lubricationAccording to the equipment requirements, regularly lubricate the bearings to ensure sufficient and clean lubricating oil.
• Clean the bearingsRegularly clean the impurities and moisture inside the bearings to keep them clean.
• Adjust the bearing clearanceAdjust the bearing clearance according to equipment requirements to ensure smooth operation.
• replace the bearingReplace severely damaged bearings with bearings of the same model number as the original.

5、 Electrical malfunction

Fault phenomenonThe crusher cannot start or suddenly stops during operation, and the control panel displays an abnormality.
Root cause analysis：

• The power plug or power cord is not securely connected, resulting in poor contact.
• Circuit fuse blown or circuit breaker tripped.
• Electrical components (such as buttons, relays, etc.) are damaged.
  solution：
• Check the power connectionEnsure that the power plug and power cord are securely connected without looseness or damage.
• Replace the fuse or reset the circuit breakerReplace the blown fuse or reset the tripped circuit breaker.
• Check and replace electrical componentsReplace damaged electrical components to ensure the proper functioning of the electrical system.

6、 Overheating fault

Fault phenomenonDuring the operation of the crusher, the temperature is too high, and there may even be smoke or odor.
Root cause analysis：

• Long term continuous operation leads to equipment overheating.
• Cooling system malfunction, such as cooling fan not running or water circuit blockage.
  solution：
• Shutdown coolingImmediately stop the operation of the crusher and wait for the equipment to cool down before restarting.
• Check the cooling systemEnsure that the cooling fan operates normally and the water circuit is unobstructed.
• Control running timeAvoid prolonged continuous operation, arrange production plans reasonably, and ensure that the equipment has sufficient rest time.
