18.104.22.168 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter . The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.
5. High Chrome. The grinding sound of the mill is too clear and harsh. The grinding sound value of the electric ear is 158 dB, which is obviously higher than the normal 120 dB standard. It is fully explained that the mill load is too small, the feed quantity is too small, and the steel ball impacts the liner for a long time, resulting in fracture.
We believe that with our ball charge gradation design will improve the mill production and reach higher efficiency. Superior grinding performance ： High Chrome media combining a martensitic structure with hard chrome carbides provides the optimum wear resistance against abrasion and corrosion.
High Chrome Alloy Grinding Media Balls. High chromium white cast iron grinding balls are also called high chromium alloy casting balls.Most of the wear resistant materials enterprise use medium frequency electric furnace through the melting of high quality scrap steel and chromium alloy materials after reasonable matching.What is more,they also use grinding ball metal mold and sand box mould ...
We have a 4x16 ceramic lined ball mill and we are milling precipitated calcium carbonate. We are trying to to get to a gradation of D50: 3 micron and D90: 8 micron, however we are having trouble getting the gradation down. Currently we are at a D50 of 5.5 micron and D90 of 15 micron. We are using grinding aid and running the mill at 28 rpm.
