SIMINE Gearless mill drives
operation, the SIMINE Gearless mill drive stops the mill with balanced charge, and with no time-wasting oscillations.In creep-ing mode at 0.3 rpm, the operator can directly control the mill while observing the mill and the material. Whether inching or creeping, you can dramatically shorten the mill's maintenance time, and thereby
Stirred mills
Vertimill® has 50% less footprint than a ball mill. Lower operating cost Vertimill® is an energy efficient grinding machine. They tend to grind more efficiently than, for example, ball mills with feeds as coarse as 6 mm to products finer than 10 microns. This provides up to a 40% higher energy efficiency.

Power to the pits
— The rod mill and ball mill combination uses motors that ranges from 2400 hp to 5000 hp. The semi-autogenous grinding mills use motors up to 15,000 hp followed by ball mills driven by 4000 hp to 5000 hp motors. The new style sag mill process being proposed for new mines may use up to 28,000 hp using wrap around motors to drive the mills.

Ball mill principle: An explanation of operation and …
Principle of Ball Mill Operation. The ball mill operates by rotating a cylinder horizontally and partially filled with balls. The cylinder's rotation causes the balls to cascade and fall back into the mill, generating impact and friction against the material to be ground. The following are the key components of a ball mill: 1.
Ball Mill
— 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 cylinder shape of the ball mill, it can be divided into cylindrical ball mill and cone ball mill.
