The basic strategy works by maximizing the SAG mill power, using a microphone or vibration sensor on the shell to indicate when the impact energy is low, and when the speed can be increased. Alternatively, if high energy impacts are detected, the SAG mill speed is reduced to protect the liners. Although this works well in most scenarios ...

Table Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl liner.Gyratory crushers are very similar to cone crushers, but have a steeper cone slope and a concave bowl surface. As the gap …

The operation of the cement raw mill is a critical step in cement production. By grinding the raw materials into a fine powder, these powders can be more easily mixed with other cement ingredients and burn more evenly during the cement clinker process. Therefore, the efficient operation of the cement raw mill directly impacts the production …

Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is "pumped" out and discharged.

• Critical size is a term used to describe coarse ore that builds up in a SAG mill. It is hard. But the reason it builds up is that the mill does not have enough power to grind it. • Autogenous Work Index or AWi is a term used to relate SAG mill Feed and Product sizes to consumed energy, using Bond equations.

AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit.
