Cyclone common problems and solutions
Faults | Reasons | Solutions |
Low recovery rate gangue high calorific value | 1. The underflow nozzle is smaller in diameter or unreasonable installation angle 2. The specific gravity setting is unreasonable | 1. The diameter of the underflow nozzle should be large,adjust angle or exchange 2. Reset and compare with test results,calibrating gravimeter |
Unsteady pressure or pressure is no enough | 1. The liquid level of combined barrel and mixing barrel is low 2. There is coal block at the inlet of the horizontal flow pipe of the mixing barrel | 1. Adjust barrel position 2. Cleaning; Check if the air duct valve is closed |
Cyclone leakage | 1. Cyclone body connection gasket is damaged 2. The cyclone body has a leakage | 1. Stop and replace the mat 2. Check the leak parts and replace the parts |
The underflow contains much light material | 1. Low feed pressure 2. Larger wear of outflow port | 1. Raise and stabilize feeding pressure 2. Check the size of the outflow port and replace the materials |
Abnormal noise in cyclone during normal operation | 1. Raw coal is mixed with iron or wear-resistant bricks | 1. Stop and turn on the cyclone to check and remove foreign matter |
Feeding inlet, outflow port or overfolw port was blocked | 1. Foreign matter was mixed in the material 2. Material size is too large | 1. Open the feeding inlet, outfilw port, overflow port and clean up the blockage 2. Check the material size and adjust |
