— Cytec Handbook. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70).
Reason: This is a common problem mining ball mills face, resulting in low productivity and low ore processing efficiency. One reason may be the improper design of the grinding chamber, which affects the flow of materials and reduces grinding efficiency. Additionally, worn or damaged liners can hinder the grinding process by reducing the effective impact …
