Ball & Rod Mill Density How Water Impacts Grinding
Aug 06, 2015· Ball & Rod Mill Density How Water Impacts Grinding. Density, if you recall is the ratio of ore to water and is measured as a percent of solids in the water. It will control the grind in two ways. It affects retention time and helps distribute the ore through-the mill so each piece of rock will come in contact with the surface of the rods.

What affect the density of grinding ball in ball mill
For the dense internal organization, forging and hot rolling balls have a high density. While compared with forging balls, casting ones have air pores in the inner structure, thereby the density of casting balls is relatively low. Shandong Iraeta is equipped with hot rolling automatic production lines with annual output of 200000 tons.

Calculate and Select Ball Mill Ball Size for Optimum Grinding
Aug 02, 2013· In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
