Peripheral discharge ball mill, and the products are discharged through the discharge port around the cylinder. According to the ratio of cylinder length (L) to diameter (D), the ball mill can be divided into short cylinder ball mill, L/D ≤ 1; long barrel ball mill, L/D ≥ 1–1.5 or even 2–3; and tube mill, L/D ≥ 3–5. According to the ...

It is an approximation or a best guess based on limited data. This equation is: y = 225 – 1.94 x (1) Where x = the load in the mill expressed as measured % by volume and y = kg/h of feed. This information is based on observed throughput reductions caused by loading the 3-ft. SAG mill to over 26% by volume.

Ball mills are used primarily for single-stage fine grinding, regrinding, and as the second stage in two-stage grinding circuits. According to the need ball mill can be either for wet or dry designs. Ball mills have been designed in standard sizes of the final products between 0.074 mm and 0.4 mm in diameter.

In this case, impurities are removed by sieving, aspiration, and gravity separation. 3.
