Environment clearance ball mill quartz

Dec 19, 2017 Tests 2 and 4 indicate cathodic protection to be very effective in reducing materials loss by 40 to 50 % when grinding quartz and pyrite. This result suggests that cathodic protection can be used directly in an industrial ball mill to reduce liner wear appreciably. Cathodic protection was used effectively to reduce materials loss in tumbling

    Under the same conditions of mill rotary rate and charge ratio, the mixture of iron powder and quartz sand (Fe/SiO (2)) was found best in promoting the mirex destruction. Mirex was completed destroyed after 2 h grinding at a charge ratio of 36:1 (reagent/mirex, m/m) and a mill rotation speed of 550 rpm. No organic compound was detected by GC

    Jan 15, 2021 After the mining ball mill has been running for a while, the felt on the gear end-face loses its elasticity after being squeezed for a long time, causing gaps in the felt. Once the mining ball mill is in a dusty operating environment, dust and impurities will enter the gap, affecting the mining industry
