Learn MoreBall mill is mainly used for grinding in mining (metallic minerals and non-metallic minerals), cement, refractories, chemical, power plant, aluminum ,building material, glass, ceramic, steel slag and fly ash, ect. It follows more crushing and less grinding principle to save energy. The feed size to ball mill shall be smaller than 25mm, the output size can be adjusted by revising steel balls ratio.
Learn Moresignificant variation of balls filling degree. As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill…
Learn MoreThe large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition. The degree of milling in a ball mill is influenced by; a. Residence time of the material in the mill chamber. b.
Learn MoreThese ball mills are often called planetary ball mills. The rotating drums are not usually detachable -- the material is poured into the top and the cap is replaced, like a kitchen blender. Like all ball mills, the speed and ball size have an effect on how the vertical ball mill works.
