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.
jan 03, 2014 then there are the environmental impacts. according to the united nations environment program, small-scale gold mining is responsible for percent of global mercury emissions and is the largest ball mills an overview sciencedirect topics. 3611 ball milling ball mill is a type of grinder used to grind and blend bulk material into qds nanosize using different sized balls the working principle is simple; impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell
