White corundum grinding powder manufacturing process impurities determine the service life
White corundum raw material for grinding wheel factory furnace core material or bulk material A1203 crystal, the content is greater than 98.5, its particle size is 36#,46#,100#, the content of Si02 in the raw materials used should be as little as possible, in order to prepare white corundum grinding powder, its manufacturing process is as follows: 1. The equipment used includes ball mill (150x 300,260x 300,350x 500), glass cylinder (300x 500), high temperature electric furnace, oven, washing tank and ventilation box, etc. 2. The manufacturing process is briefly described as follows: A. Crush and put the quenched steel ball copper raw materials with different diameters into the drum.
