The common problems and solutions of GM-5M laboratory mini vibrating screen are as follows:

1. Screen blockage

Reason: The material has a high moisture content, too many flaky particles, and an unreasonable mesh design. ‌

Handling method:

Reduce the moisture content of the material (drying treatment is required when the moisture content is>5%).

Adjust the tension of the screen mesh and maintain slight secondary vibration.

Optimize the sieve design to avoid stuck holes.

2. Excessive noise

Reason: Loose screen mesh, worn bearings, faulty transmission components, or foreign objects getting stuck. ‌

Handling method:

Re fix the sieve and leave a reasonable gap.

Replace worn bearings or lubricating oil.

Tighten transmission components or clean foreign objects.

3. Abnormal device startup

Reason: Heavy load start-up, damage to the damping system, or installation issues. ‌

Handling method:

• Avoid heavy load start-up and clean up the accumulated material inside the sieve box.

Check and replace failed springs to ensure consistent spring stiffness.

During maintenance, ensure that the motor model is the same, the direction is opposite, and the vertical plane is consistent. ‌

4. Bearing overheating

Reason: Insufficient lubrication, cooling system malfunction, or bearing damage. ‌

Handling method:

Regularly check the bearing lubrication and replace the lubricating oil.

Check if the cooling system is working properly.

Timely replace damaged bearings. ‌

5. Vibration reduction system malfunction

Reason: Spring failure, excessive accumulation of material under the screen, or improper installation. ‌

Handling method:

Regularly inspect springs, replace faulty springs, and ensure consistent stiffness.

Clean the screened material and maintain coordination of the vibration reduction system. ‌
