µm. Note that—in order for no correction factor for ball mill product fineness to apply—the ball mill circuit P80 should be no less than approximately 70 µm (Bond, 1962). This Bond Efficiency determination should not be applied to cir-cuits with a P80 finer than approximately 70 µm without making qualifications. 3.

The mill grinding process is almost carried out in two consecutive stages: one is dry grinding (coarse grinding) and the other is wet grinding (fine grinding). The key grinding equipment are ball mills and rod mills, and the latter is now mostly used for wet grinding to finally produce fine and uniform ore products.

Control Feed Size. The particle size of the material entering the ball mill is controlled between 25-15 mm (the diameter of the ball mill is different for different feed sizes). Excessive rules will cause the ball mill to have too much fine material during the grinding process and cannot achieve the friction between the material and the material.

Influence of ball mill structure on grinding efficiency. The grinding efficiency of a ball mill is affected by many factors, but one thing you may not know is that the structure of the ball mill also affects the grinding efficiency.This paper will discusses this problem from four aspects: barrel length, diameter, ball mill speed and lining plate.

01 1.Increasing the grindability of raw ore. Commonly, the grindability is determined by the hardness, degree of dissociation, size and structure of raw ore. The small grindability means that the raw ore is easy to grind, which has relatively small wear on the liner and grinding media of the ball mill and low energy consumption.

In the first survey the ball mill was underperforming due to the low density in the mill, which was rectified in the second survey. The ball mill was grinding to a P 80 of 50 to 70 µm, therefore the traditional marker size (75 µm) was not applicable, and this can be seen by the increase in SSE for coarser sizes as the marker size approached P ...
