在球磨机的粗磨室中,Vcesi-Alpine 设计一种有槽的衬板。在磨机的内表面衬板上,并列重叠排着一圈一圈环状的槽,槽的截面呈园弧状。当磨机运转时,最大的钢球移向最外,并贴着衬板表面,按最大密度紧凑排列。钢球坐落在衬板表面上的槽内。从磨机运转方向看去,排列在槽中的钢球,在左右二边各有60°的重叠。钢球与槽有120度弧长的接触。这要比
Vcesi-Alpine designed a slotted liner in the mill’s roughing chamber. On the inner surface of the mill liner, juxtaposed in parallel circle lined circle of grooves, groove cross section was circular arc. When the mill is running, the largest ball moves to the outermost, and close to the lining surface, compactly arranged by maximum density. The ball is located in the groove on the surface of the liner. When viewed from the running direction of the mill, the balls arranged in the grooves have a 60 ° overlap on each of the left and right sides. Steel ball and groove arc of 120 degrees long contact. This is more than
