Customers who know about ball mills know that ball mill linings bring many benefits to ball mills, which not only reduce the consumption of ball mill equipment, but also reduce production costs. After this lining is installed in the ball mill chamber, a square truncated cone with four rounded corners will be formed in the ball mill chamber, so it is also called a rounded square lining. What effect will the installation of this liner in the ball mill chamber have on the ball mill? What's different? The rotation and falling speeds of balls and materials are different, which causes strong friction between the ball and material curtain surfaces of adjacent ball mill linings.
The radius of gyration of each layer of steel balls changes instantaneously, causing the falling height, landing point and impact kinetic energy of the same layer of balls to change accordingly, thereby enhancing the mixing and penetration of the grinding media and materials.
, has a good positive classification effect on steel balls. The phenomenon of over-grinding is significantly reduced (the degree of reduction is more significant for open-circuit mills). The ball mill operates more smoothly and the service life of the transmission device is longer.
After installing this kind of ball mill lining plate, the effective volume of the warehouse is reduced than when installing ordinary lining plate. Generally, the effect is good on large (above millimeter) mills. The installation and removal of this kind of lining plate is difficult. When using this kind of ball mill lining, the amount of balls should be appropriately reduced, the average ball diameter of a warehouse should be increased, and the moisture content of the grinding materials should be strictly controlled.
The propulsion force of the internal rotation surface causes the balls in the same ball diameter area to generate local axial vortices, which enhances the grinding ability.
The rotation direction of the ball mill liner is opposite to the rotation of the mill barrel. In this way, from the perspective of the total length of the ball mill barrel, the grinding cavity in the entire ball mill barrel forms a continuous four-head spiral. The spiral surface in the rounded corner of the liner has a strong grip on the small balls, pushing the small balls to the discharge end. At the same time, the thrust of the spiral angle pushes the big balls to the feed end. Therefore, this kind of ball mill lining can be better It can effectively realize the forward grading of steel balls, and its grading effect is better than that of the conical grading liner.
