Get PriceThere is no standard solution for mineral industry andwear rateof grinding media varies from mine to mine, ore to ore and even for the same ore time to time. Different alloys are recommended depending on ore type andmillparticulars in order to arrive at the most cost economic solution.
Get PriceThe grinding wear conduct of these materials are evaluated for the wear loss under the wet milling conditions. The grinding processes were carried out for 60 minutes of time at the speed of 86 rpm and a pulp density of 60 % under sealed mill conditions .The slurry pH value is varied from 7 to 10.5 to evaluate the impact of pH on grinding wear performance of ball material.
Get PriceTherefore, for largeballs, the hardness difference between inside and outside is lbig, after entering theball mill, after 12-13mmwear, the hardness decreases rapidly, the overallwearincreases, which will lead to the loss of roundness and affect the output of the ore platform.
