In the ore beneficiation process of lead-zinc, wet grinding circuit is primarily utilized. The grinding circuit consists of the following basic components: rod mill, ball mill, and a set of hydrocyclones and sumps [4, 39].Prior to passing into the grinding circuit, crushing of the ore is initially performed using primary crusher followed by secondary crusher.
Normally, we are mostly worried about battery getting over charged, and forget about a situation where the battery can get over discharged by the load.Although, overcharging a battery may be detrimental to a battery health and appropriate measures must be incorporated, an over discharge or a deep discharge can be also equally …
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 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.

As we saw in the previous tutorial, in a RC Discharging Circuit the time constant ( τ ) is still equal to the value of 63%.Then for a RC discharging circuit that is initially fully charged, the voltage across the capacitor after one time constant, 1T, has dropped by 63% of its initial value which is 1 – 0.63 = 0.37 or 37% of its final value. Thus the time constant of …
