The cone ball mill is a commonly used device in the grinding operation. At present, the cone ball mill has been widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal seasonings, glass ceramics and other production industries, suitable for all ores. Drying or wet milling is carried out with other coarable material. Steel ball is an important grinding device in a cone ball mill cylinder. The applicability of the steel ball directly affects the work efficiency of the cone coil mill. In addition, the speed of the steel ball also affects the work efficiency of the tapered ball mill, then the speed of the ball in the grinding operation is mainly related to those factors? When the steel ball of the conic ball mill is moved with the cylinder, between the liners and the laminate, the friction between the slab and the ball and the other layers of the ball will cause rotation to rotate the steel ball. However, the centrifugal force of each layer is different, and the friction is different, so the speed of each of the tapers is different, so when the steel ball is moved, the ball is also opposite the slide ball. In order to extend the life of the lining, the relative slide of the outer ball should be reduced. The rotational speed of the steel ball of the tapered ball is related to the radii of the rotation, and the rotation speed of the outer steel ball is greater than the rotational speed of the inner grinding ball. When the steel ball is close to the same layer or the radius of the ball, the speed of the ball mill is also related to the position of the steel ball. The higher the position of the steel ball, the smaller the speed.
