Get Priceball mill is suitable to grind various mineral and other materials, which is widely used in various industries such as benefication, construction materials, chemical industry, etc, it has two ore grinding ways: dry way and wet way. according to discharge type of finished powder, it can be divided into two kinds: grid type and overflow type.ball mill is a type of grinder machine which uses steel ball as grinding medium, can crush and grind the materials to mesh or finer, adopted in open or close circuit. the feed materials can be dry or wet, they are broken by the force of impact and attrition that created by the different sized balls.ball mill is mainly used for grinding in mining 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 the output size can be adjusted by revising steel balls ratio.the type of mill also can affect the selection of grinding media. ball mills use very large media while attritors employ media ranging in size from to horizontal mills require much smaller media, as small as 0.05 mm to mm.

Get Pricejun 01, 2018 this analysis technique showed that the required product fineness is a function of grinding media and feed material size distributions. It was also observed from the experimental results that in order to increase the milling efficiency of a ball mill, towards optimum production of material in the desired size class, there is a need to correlate ball mills are the most effective laboratory mills for rapid batchwise comminution of medium-hard, soft, brittle, fibrous, and moist samples down to the finest particle size. the comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding grinding materials to nano-size? In the second case the kinetic energy is firstly transferred to the mill body and then to the grinding medium. these ball mills are the most widely used in the you probably know that grinding in ball mills is a crucial technological process applied to reduce the size of particles. the particle may have different nature and diversity of physical and chemical characteristics. machine is used to reduce the particle size of materials. the ball mill is a
