The ball mill is the keyequipment for crushing after the material is crushed. It is a kind of equipmentin which a certain number of steel balls are loaded as grinding media.
The ball mill is widely usedin production industries such as cement, silicate products, new buildingmaterials, refractory materials, fertilizers, ferrous and non-ferrous metalbeneficiation, and glass ceramics, for dry or wet grinding of various ores andother grindable materials. The ball mill is suitable for grinding various oresand other materials. It is widely used in mineral processing, buildingmaterials and chemical industries. It can be divided into dry and wet grindingmethods. According to the different discharge methods, it can be divided intogrid type and overflow type.
The ball mill adopts ahorizontal cylindrical rotating device, and the outer edge of the gear drive.The material enters the first silo of the mill evenly from the feeding devicethrough the feeding hollow shaft. The bin has a stepped lining or corrugatedlining. It contains steel balls of different specifications. The rotation ofthe cylinder produces centrifugal force to bring the steel ball to a certainheight. After falling down, it will hit and grind the material. After thematerial reaches rough grinding in the first silo, it enters the second silothrough a single-layer partition board. The silo is set with a flat liningplate and has steel balls inside to grind the material further. The powder isdischarged through the discharge grate plate to complete the grindingoperation.
The main function of thesteel ball in the ball mill is to crush and crush the materials, and also playa certain grinding role. Therefore, the purpose of grading steel balls is tomeet the requirements of these two aspects. The quality of the crushing effectdirectly affects the grinding efficiency, and ultimately affects the output ofthe ball mill; the parameters that determine the fineness of the ball mill,such as the size of the ball mill, mainly include the size of the steel ball,the number of ball diameter series, and the proportion of variousspecifications of the ball.
The ball mills are mainlyclassified according to mechanical methods, including cement ball mills, tubeball mills, ultra-fine laminating mills, cone ball mills, ceramic ball mills,intermittent ball mills, overflow ball mills, lattice ball mills, winddischarge ball mills, double warehouse ball mills, etc. .
