Mill structure refers to the mill liner, cylinder plate, diaphragm and into the discharging device. The mill liner is mainly used to protect the cylinder, avoid direct impact grinding body and material on the cylinder and friction, then can use different types of lining board to adjust the state of motion the inner grinding body. The material in the grinding process, because the first warehouse material size is large, the grinding body to impact requirements, should drop the grinding body; and fine grinding chamber material is small, so that products meet the requirements of grinding fineness, grinding grinding is the main body to the requirements, the grinding body should a pouring state. The grinding body falling or pouring state depends on the state of grinding different speed, but only a fixed speed mill, the grinding body and the motion state requirements of the conflict, in order to solve this contradiction, lining board can use different surface shapes (such as flat lining, batten plate, rib corrugated liner, spiral ladder liner, liner, ditch worse, the liner) movement form and grinding body with different friction coefficients to change the grinding body, in order to adapt to the material grinding process requirements, to improve the grinding efficiency.
A lining board 1, the inner wall of the cylinder cover and protect the ball by grinding body wear 2, adjust the grinding body motion, the grinding body in mill operation in the process of rational use of energy. As in a warehouse loaded ladder liner or layer lining board can make the Dayan mill body lifting height increase the grinding body to crush materials with large kinetic energy, in fine grinding chamber with corrugated liner or flat lining, can make the abrasive grinding body is enhanced. 3, enhance the stiffness of the cylinder to a certain extent. 4, grading lining plate can make the ball inside the warehouse according to the ball size along the axial direction of the mill as to classification, so that the diameter of steel ball and give full play in the grinding process. the most common liner wear phenomenon is the formation of groove shape. To avoid this, the surface shape of ball mill liner for various improvements, the grinding body falling from one of the various slot distribution. Two effect of mill diaphragms is:
1, the grinding body separated. During the grinding process, reduce the particle radial grinding tail direction of motion of the grinding body is required by the start of the impact and gradually changing the grinding effect, the use of diaphragms can impact the grinding body (such as large the ball) and the grinding of the grinding body (such as steel and steel balls). At the same time also can be classified to impact grinding body mainly according to the impact of the size of the rough classification (such as in a mill, two positions).
2, to prevent the large particles flow to the discharge end, diaphragm plate of material sieving effect, allowing only less than sieve through the material, to prevent large particles into the impact of weak area; the control of grinding material in the flow rate, number of diaphragms on the mesh size, the arrangement can be affected by the ability of materials; which can control and improve ventilation mill, thereby determining the filling degree of grinding material, grinding time control material subjected in grinding, can play the yield and quality of unity, stability of mill normal production.
