ball drum mill. design, structure diagram, operating principle, calculation basis. It is clear that an industrial mill is one of necessary components of a grinding and screening complex. using the mills, different ore and non-ore mineral resources, average hardness construction materials, slags and production waste materials are ground.
the charge volume of a ball or rod mill is expressed as the percentage of the volume within the liners filled with balls or rods. when the mill is stationary, the charge volume can be quickly obtained by measuring the diameter inside the liners and the distance from the top of the mill inside the liners to the top of the charge.
We can calculate the steel charge volume of a ball or rod mill and express it as the of the volume within the liners that is filled with grinding media. while the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.
apr 08, 2021 In grinding, selecting the correct or optimum ball size that allows for the best and optimumideal 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 andor mill liner wear and tear.
