— 1. Introduction1.1. Background. With the continual depletion of high grade simple ore bodies, more complex, finely disseminated ore bodies are being processed, which has led to an increase in the prevalence of fine grinding (Sinnott et al., 2006).This has been evident in the platinum group element (PGE) industry in South Africa, where the …
Step 2: Charging the media mill. As the raw feed in the liquid slurry circulates through the mill, ... In this step, the liquid slurry with dispersed solids is circulated in the media mill along with the grinding media until the final particle size, or grind gauge, and surface characteristics are achieved. This can require multiple passes and ...
The design of mill liners can have a significant impact on grinding performance. The following are some of the effects of mill liner design on grinding performance: Mill Capacity. The design of mill liners can affect the capacity of the mill, as it determines the amount of material that can be processed at any given time. The liner design must ...
