The key of the ceramic filter is the ceramic filter plate, but if too much small particle concentrate powder is used, the filter plate will be blocked and the filtering function will be lost.
Vacuum ceramic filter filter utilization measures:
1. The ceramic filter plate is effectively regenerated. The key of the ceramic filter is the ceramic filter plate, but if too much small particle concentrate powder is used, the filter plate will be blocked and the filtering function will be lost.
Its regeneration can be achieved through: A. Prolong the cleaning time, increase the cleaning frequency, ensure the regeneration rate, shorten from 8h/time to 6h/time, extend the time from 40min to 60minb, increase the current, increase the ultrasonic intensity, improve the cleaning efficiency, and generally control the current at 8A
2. Increase the pulp concentration and temperature. After ball milling, the concentration of the iron concentrate pulp increases from 65% to over 75%, the temperature of the pulp increases, and the utilization coefficient of the filter material increases, which can be considered from this aspect.
3. Reduce the damage rate of the ceramic plate. The ceramic plate is damaged, the ore pulp is mixed into the filtrate, the cleaning liquid is polluted, and the utilization rate is reduced. The main causes of damage are the fixation of the mixer, scraper, ceramic plate, and the collision of garbage entering the slurry tank. a. The correct installation of the mixer, scraper and ceramic plate requires B. Timely replacement and cleaning to prevent blockage and aggravate wear; C. Improve the strength of the ceramic plate.
4. Reduce the seal damage of the filtrate pump. The seal of the filtrate pump leaks water, and the suction of the filtrate is insufficient to enter the vacuum pump, which burns the motor and the pump body and causes the filtrate to stop. A. It is necessary to modify the filter pump, replace packing seal with mechanical seal B, adopt reasonable filter pump parameters C, and increase automatic detection.
