Hydrocyclones: 11 Troubles and Troubleshooting

Trouble 1: low Underflow Density

Troubleshooting

If the hydrocyclone is not fed correctly, replace the discharge nozzle/overflow pipe;

The size of the discharge nozzle is incorrect, use the correct size discharge nozzle.

Trouble 2: Hydrocyclone Vibration Violently

Troubleshooting

If empty suction occurs, use the suction pipe.

A large amount of material, change the feed/hydrocyclone parameters;

Linear layout, control entrance;

The overflow pipe is deformed and the overflow pipe is replaced;

Local blockage in the hydrocyclone, stop and check.

Trouble 3: Hydrocyclone Blockage

Troubleshooting

The mismatched material enters the hydrocyclone and checks the sieve hole.

Trouble 4: Abnormal Over-Granularity

Troubleshooting:

Underflow nozzle is worn seriously, so replace the suitable underflow nozzle.

If the feeding density is too high, check the blockage;

Feed reverse flow, replace easy-to-grind parts.

Trouble 5: Cannot Reach Cut Point

Troubleshooting

The feed size is incorrect, replace the feed/hydrocyclone parameters.

Trouble 6: Unstable Performance

Troubleshooting

Uneven distribution of materials, the use of the correct distributor;

Blockage, check for blockage.

Trouble 7: Unstable Operating Pressure

Troubleshooting

The pump and the hydrocyclone are unbalanced, isolate the hydrocyclone to achieve a stable operating pressure or reset the pump speed.

Trouble 8: High Wear Rate

Troubleshooting

The flow rate is too large-the pressure drops too much, change the feeding condition or hydrocyclone parameters;

2-stage operation / need large size hydrocyclone, change hydrocyclone parameters;

The wearability of the incoming material is high, and the manufacturing material should be replaced.

Trouble 9: Overflow Occurs

Troubleshooting

The pipeline of the follow-up system is limited or blocked, and the restriction is cancelled.

Check the angle of the line and the size of the line in the discharge area.

Trouble 10: No Fan Flow is Formed

Troubleshooting

large coal amount and foaming coal proportion, reduce the carrying coal;

Unreasonable pressure setting, adjust pump frequency;

Feed pump opening small, open the valve;

Trouble 11: Underflow With Too Many Materials

Troubleshooting

Cut off the solid feed and replace it with a large discharge nozzle;

Check whether the discharge nozzle and feed pipe are blocked.
