Fault and Solution of Sand Sprial Classifier
In this text, we will talk about the fault and solution of sand spiral classifier.
※ Motor current is unstable or too high
Reason: 1. Sand return is increased. 2. Feeding concentration is too high. 3. The steel ball discharged by ore pulp from ball mill is increased. 4. V belt is too tight.
Solution: 1. Reduce sand return or feeding concentration. 2. Clear the steel ball in time. 3. Adjust V belt. It is advisable to be pressed down 10-15mm.
※ Processing capacity is decreased
Reason: 1. Big tilt angle of trough body causes grading area decreased. 2. Pulp density is too low.
Solution: 1. Reduce tilt angle. 2. Adjust the pulp density.
※ Grading precision becomes low
Reason：1. The overflow weir is not high enough. 2. Slurry concentration is too high or too low.
Solution: 1. Adjust the plate height. 2. Adjust to proper slurry concentration.
※ Cannot form sand return or sand return amount is reduced
Reason: 1. Spiral blade is worn. 2. Spiral rotation speed is too low.
Solution: 1. Replace a new spiral blade. 2. Adjust the rotation speed.
※ Vibration of classifier, gear drive with a crash or sudden strong vibration
Reason: 1. Gear engagement is bad or worn too much. 2. Drive bearing wear out too much. 3. Insufficient lubrication.
Solution: 1. Adjust gear clearance or replace a new one. 2. Replace bearing. 3. Add sufficient lubrication oil.
