How to maintain the flotation machine?

Flotation machine maintenance
1. Parts that need to be checked frequently during the operation of the flotation machine

(1) Overheating of the rolling bearings in the motor and impeller body. Generally, the bearing temperature shall not exceed 35℃, and the upper limit temperature shall not exceed 65℃.

(2) Check the tension of the transmission belt. The tightness should be appropriate. If serious wear is found, a belt with the same length and model should be selected for replacement.

(3) Check the sealing of the oil seal rubber ring. In particular, pay attention to the grease in the bearing body not leaking into the slurry to avoid affecting the normal flotation work.

(4) Check whether there is enough grease at each lubrication point. If the oil is insufficient, add it in time.

(5) Check whether there are other debris in the tank.

2. Several aspects that should be paid attention to when repairing the flotation machine

(1) When replacing the worn impeller and stator, the gap between the impeller and the stator should be adjusted with a gasket to keep the gap within the range of 6-10 mm.

(2) Before installing the impeller, check whether the hose protecting the main shaft is worn. If worn, replace it with a new hose.

(3) If the axial clearance of the bearing is too large due to wear, just adjust the tightness of the inner and outer races.

(4) If the oil seal under the bearing body is found to be leaking, replace it with a new one in time, and be careful not to press it too tight.

3. Precautions for test run and use of flotation machine after overhaul

After the flotation machine is overhauled, before the test run, the flotation tank should be carefully checked and cleaned, and then an empty car test run should be carried out, and clean water should be gradually added to run (pay attention to adjust the size of the circulation hole) until the ore is fed. At the same time, pay attention to check whether the impeller body has deflection and impact.

When starting the motor, check the rotation direction of the motor shaft, and make sure that the impeller shaft rotates clockwise (looking down).

When using, attention should be paid to the adjustment of the slurry level, that is, the degree of gate opening. Only by adjusting the height of the slurry level in time can the foam be effectively scraped out and the slurry be prevented from overflowing into the foam tank.
