What's the Difference Between SAG Mill and Ball . Nov 26, 2019 The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm.

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

In ball milling, the desired particle size is achieved by controlling the time, applied energy, and the size and density of the grinding media. The optimal milling occurs at a critical speed. Ball mills can operate in either a wet or dry state. While milling without any added liquid is commonplace, adding water or other liquids can produce the ...

Dipak K. Sarkar, in Thermal Power Plant, 2015 4.6.1 Low-speed mill. Mills operating below 75 rpm are known as low-speed mills.Low-speed units include ball or tube or drum mills, which normally rotate at about 15–25 rpm.Other types of mills, e.g., ball-and-race and roll-and-race mills, that generally fall into the medium-speed category may also be …
