Common faults and treatment methods of spiral classifier

Common faults of spiral classifiers include:

1. The spiral blade is worn. Over time, the spiral blade of the spiral classifier can become worn and lose its shape, leading to reduced efficiency and accuracy.
2. The shaft is bent. If the shaft of the spiral classifier is bent, the spiral blade will not be able to rotate properly, reducing the efficiency of the classifier.
3. The bearing is damaged. Damage to the bearing can cause the spiral shaft to become jammed, making proper operation of the classifier impossible.
4. The motor is malfunctioning. A malfunctioning motor can cause the spiral classifier to fail to operate properly.

Here are some possible treatment methods for these faults:

1. Replace the spiral blade. If the spiral blade is worn, it should be replaced to restore the efficiency and accuracy of the classifier.
2. Repair or replace the shaft. A bent or damaged shaft should be repaired or replaced to ensure proper rotation of the spiral blade.
3. Replace the bearing. If the bearing is damaged, it should be replaced to avoid jamming and restore proper operation of the classifier.
4. Repair or replace the motor. If the motor is malfunctioning, it should be repaired or replaced to ensure proper operation of the classifier.

Here is a list of common faults and their treatment methods for spiral classifiers:

Common Faults:

The overflow of the classifier is low.

The tailings flow is unstable.

The discharge opening of the classifier is blocked.

The spiral blade is worn or damaged.

The bearing is overheating.

The motor doesn't start.

There are abnormal noises during the operation.

The water supply is insufficient.

Treatment methods:

Adjust the water supply or the position of the weir, or increase the spiral speed to increase the overflow.

Adjust the water supply or the position of the weir to stabilize the tailings flow.

Clean the discharge opening or adjust the position of the device to eliminate blockage.

Repair or replace the worn or damaged spiral blade.

Check and adjust the bearing clearance, lubricate the bearing or replace the bearing.

Check the power supply and circuit or replace the starting capacitor.

Check the wear of the spiral blade or the bearing, or tighten the connecting bolts.

Increase the water supply or clean the water pipe and valve to ensure sufficient water supply.

Here is a table summarizing the common faults and their treatments:

Common Faults Treatment Methods

Low overflow of classifier Adjust water supply or increase spiral speed

Unstable tailings flow Adjust water supply or position of the weir

Discharge opening blockage Clean or adjust discharge opening

Worn or damaged spiral Repair or replace the spiral blade

Overheating bearings Check and adjust bearing clearance, lubricate

Motor doesn't start Check power supply and circuit or replace cap

Abnormal noises Check wear or tightness of blade or bearings

Insufficient water supply Increase water supply or clean water pipe
