Ball mill is a horizontal grinding mill and key equipment for grinding materials, widely used in ore flotation processing plant and powder-making production line. According to different materials and discharging methods, there are dry ball mills and wet ball mills for choice. Dry ball mill is mainly for producing mineral powder used in cement, silicate product, new building material, refractory, fertilizer, black and non-ferrous metals and glass ceramic industry; Wet ball mill is a kind of continuous ball mill used in ore beneficiation plant. ...Learn More

In grinding selecting calculate 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 andRead More
Theory the ball mill is used for fine grinding of soft materials here the size reduction is done by the impact of ball which are generally 1" to 5" in diameter the mill operates in batch as well as continuous manner when the mill is rotated the balls are carried to the top in the mill and they fall down giving an impact on the materialRead More
Ball hardness is in the 6067 hrc range they wear better than 440c stainless steel and throughhardened carbon steel they are also recommended for applications where a throughhardened steel ball is needed in larger sizes and larger they are sometimes packaged with a very light oil finish to reduce rust due to humidity sae 52100Read More
