What are the common problems with a Plastic Granule Lift Machine and how to solve them?

Oct 28, 2025

Hey there! As a supplier of Plastic Granule Lift Machines, I've seen my fair share of issues that customers run into. In this blog, I'll talk about some common problems with these machines and how you can solve them.

1. Blockages in the Conveyor System

One of the most common issues with Plastic Granule Lift Machines is blockages in the conveyor system. This can happen for a few reasons. First off, if the plastic granules are too large or have an irregular shape, they might get stuck in the conveyor tubes or channels. Also, if there's dust or debris mixed in with the granules, it can build up over time and cause a blockage.

How to Solve It:

  • Regular Cleaning: Make sure to clean the conveyor system regularly. You can use compressed air to blow out any dust or small particles that might be accumulating. If you're looking for a good air compressor for this job, check out our Oil Free Air Compressor. It's reliable and can help keep your conveyor system clean.
  • Size Screening: Before loading the plastic granules into the lift machine, use a screening device to separate out any oversized or irregularly shaped granules. This will prevent them from causing blockages in the first place.

2. Motor Overheating

The motor is the heart of the Plastic Granule Lift Machine, and overheating can be a real problem. It can be caused by several factors. For example, if the machine is overloaded with too many plastic granules, the motor has to work harder, which generates more heat. Also, poor ventilation around the motor can prevent heat from dissipating properly.

How to Solve It:

  • Load Management: Don't overload the lift machine. Make sure to follow the manufacturer's recommended load capacity. If you need to move a large amount of plastic granules, do it in multiple smaller batches.
  • Improve Ventilation: Ensure that the area around the motor has good airflow. You can use an Air Chiller Cooling Machine to cool the air around the motor and prevent overheating. It's a great solution for keeping the motor at a safe operating temperature.

3. Belt Slippage

Many Plastic Granule Lift Machines use belts to move the granules up and down. Belt slippage can occur when the belt is loose or when there's too much dust or debris on the belt surface. This can lead to inefficient operation and even damage to the belt over time.

How to Solve It:

  • Belt Tension Adjustment: Check the belt tension regularly. If it's too loose, adjust it according to the machine's manual. Most machines have a simple mechanism for tightening the belt.
  • Belt Cleaning: Clean the belt regularly to remove any dust or debris. You can use a soft brush or a cloth to wipe the belt surface. This will improve the grip between the belt and the pulleys and prevent slippage.

4. Noise and Vibration

Excessive noise and vibration can be a sign of a problem with the Plastic Granule Lift Machine. It could be due to loose parts, misaligned components, or worn-out bearings.

How to Solve It:

  • Tighten Loose Parts: Inspect the machine regularly and tighten any loose bolts or nuts. This can often reduce noise and vibration significantly.
  • Alignment Check: Make sure that all the components of the machine are properly aligned. If you're not sure how to do this, refer to the machine's manual or contact our technical support team.
  • Bearing Replacement: If the noise and vibration are caused by worn-out bearings, replace them as soon as possible. Worn bearings can cause further damage to the machine if left untreated.

5. Leakage of Granules

Sometimes, plastic granules can leak out of the lift machine, which can be a mess and a waste of materials. This can happen if there are gaps or holes in the conveyor system or if the seals are damaged.

How to Solve It:

  • Seal Inspection and Replacement: Check the seals around the conveyor tubes and other components regularly. If you find any damaged seals, replace them immediately. This will prevent granules from leaking out.
  • Repair Gaps and Holes: Inspect the conveyor system for any gaps or holes and repair them. You can use appropriate sealing materials to fill in the gaps and prevent leakage.

6. Control System Malfunctions

The control system of the Plastic Granule Lift Machine is responsible for regulating the operation of the machine. Malfunctions in the control system can cause the machine to stop working or operate erratically.

How to Solve It:

  • Check Electrical Connections: Make sure that all the electrical connections in the control system are secure. Loose connections can cause malfunctions.
  • Software Updates: If your machine has a programmable control system, check if there are any software updates available. Updating the software can often fix bugs and improve the performance of the control system.
  • Professional Repair: If you're unable to diagnose or fix the control system problem yourself, contact our technical support team. We have experienced technicians who can troubleshoot and repair the control system.
