The operating principle of the ball mill consists of following steps In a continuously operating ball mill feed material fed through the central hole one of the caps into the drum and moves therealong being exposed by grinding media The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls Then discharge of ground material performed...
Grate liners and ball mill liner The type of ball mill liner known as a grate liner is designed for discharge efficiency It allows the discharge of ground materials via slots With the Magotteaux range of alloys and their experience a longer lifetime and optimal grinding can be achieved...
Designed for discharge efficiency The role of the grate is to allow the discharge of the material ground in the mill via the slots With our range of alloys and design experience we can offer the longest possible lifetime with the optimal grinding efficiency The design of the grates will depend on Drilling pattern Mill speed rpm Maximum grinding media diameter mm Grinding media filling...
of grate/pulp lifter design in AG/SAG mill discharge The current understanding from literature lacks knowledge of mill content size distribution and its effect on discharge through the grate at various aperture sizes and radial positions It also indicates that in...
mill performance could become worse or better by putting in a new shell liner Data from pilot plant test work illustrates the influence of the shell lifting effect on the grind for a primary grinding duty Figure 5 shows the evolution of the mill discharge product size in relation to the lifting effect of the liners...
Jul 01 2003 0183 32 More recent work on the effect of grate design was carried out by Morrell and Stephenson 1996 in a 030 015 m laboratory mill with a vertical transparent grate Based on the results obtained they observed that the hold-up was a strong function of percent open area and the position of holes in the grate...
3 Perforated metal screens or bar grates covering the discharge opening of the mill retains coarse materials for further grinding while allowing the properly sized materials to pass as finished product Varying the screen size shaft speed or hammer configuration can dramatically alter the finished size of the product being ground...
Here I try to explain how ground slurry is discharged from a grate ball mill or SAG How it works is the slurry flows across the grate as it would a screen panel On the other side of the grate/screens are veins like a pump impeller As the mill turns/rotates the slurry is pumped out and discharged Discharge Grates The natural flexibility of rubber has allowed rubber manufacturers to...
