This chapter provides an overview of the existing mathematical models for the simulation of grinding and classification in mill–classifier circuits not only for ball mills …
A schematic diagram of the mill–classifier circuit used for the investigations is shown in Fig. 2. With the mill–classifier circuit much steeper distributions were achieved. ... The results show that the coarsest particle size distribution at the mill discharge is produced in an open-circuit mode, following the batch process. The finest and ...
Figure 8.2 shows a flow sheet where the rod mill is in open circuit and the ball mill is in closed circuit with a classifier. This is a normal set-up as the primary function of a rod mill is to provide a uniform sized feed to the ball mill. Figure 8.3 shows that the rod mill product is classified and a more uniform feed size is, therefore, discharged to the ball mill whose …
The selection of mill length is dependent upon the size of feed, size of product and type of grinding circuit selected. Considerations given a short mill are the reduced floor space, shorter retention time producing less fines in the discharge product, and the possibility of producing a slight amount of tramp oversize particles.
a. To transport solids in the circuit n Ball mills use ~35% water for milling and in the discharge water is further added for separation in solids Most flotation operations are performed in between 25 F40% solids by weight. Some gravity concentration devices operate most efficiently on slurry containing 55
Ball Mill Components. Ball mills consist of the following components: Inlet – crushed ore is fed to the ball mill through the inlet. A scoop ensures the feed to the mill is constant. Discharge – reduced feed exits the mill through the discharge. Ball Mill Components. Drum – the drum is the cylindrical casing of the ball mill.

The overflow type ball mill is suitable for fine grinding and operates in a closed circuit with a classifier. Grate Discharge Ball Mills: In this type of mill, the ground materials are discharged through the grate plate, which prevents the grinding media from exiting the mill. Grate discharge mills are used for coarse grinding.
