Maintenance and Troubleshooting of Air Classifier

Air Classifier is a device that uses aerodynamic principles to classify powder materials. It is widely used in many fields, such as: chemical, pharmaceutical, and metallurgical industries. Air classifier can efficiently separate powder materials according to particle size, to meet the precise requirements of different industries. In order to ensure its long-term stable operation and efficient performance, regular maintenance of air classifier is essential.

A detailed guide to air classifier maintenance

1. Cleaning and dust removal

Regularly clean the dust inside and outside the equipment to prevent dust accumulation from affecting classification effect.

Check that the dust removal system, such as the filter, is functioning properly.

2. Check the rotor and blades

Check the blades for wear, deformation or damage, and repair or replace them if necessary.

Ensure the rotor is dynamically balanced to avoid excessive vibration.

3. Check bearings and lubrication

Check the bearing wear and replace damaged bearings in time.

Lubricate the bearings regularly with suitable lubricants.

4. Check the seals

Check whether the seals are aged or damaged to prevent dust leakage.

Replace worn or damaged seals.

5. Check the airflow system

Check that the fan, pipes and valves are functioning properly to ensure stable airflow.

Clear any dust or obstructions in the air flow ducting.

6. Check the electrical system

Check that the motor, cables and control system are functioning properly.

Make sure electrical connections are secure and avoid short circuits or overloads.

7. Calibration and debugging

Calibrate the control system and sensors of air classifier to ensure classification accuracy.

Debug equipment parameters and optimize grading effects.

Common faults and maintenance methods

The classification accuracy decreases

Cause: Worn rotor blades, unstable airflow or sensor failure.

Maintenance: Replace blades, check airflow system and sensors

.

The equipment vibrates too much

Cause: Rotor is unbalanced, bearings are worn or not installed securely.

Maintenance: Rebalance rotor, replace bearings, and tighten mounting bolts.

Dust leakage

Cause: The seal is aged or damaged.

Maintenance: Replace seals and check whether the connections are tight.

Unstable airflow

Cause: Fan failure, pipe blockage or valve damage.

Maintenance: Clean pipes, check fans and valves.

Motor overheating

Cause: Motor overload or cooling system failure.

Maintenance: Check motor load and clean cooling system.

Safety precautions during maintenance

Before maintenance, ensure that the equipment is completely stopped and powered off.

Use personal protective equipment (e.g., gloves, goggles, masks).

Avoid performing maintenance operations while the equipment is running.

Regularly train maintenance personnel to improve safety awareness and skills.
