Introduction of Semi Autogenous Grinding Mill
Like ball mill and rod mill, SAG mill also belongs to horizontal placed cylinder grinding equipment, the working principle is basically the same, which by means of processed material itself (or add a small amount of medium) in the simple body of continuous impact, rolling grinding and make the material crushing. The filling rate of steel ball in the shell of the semi-autogenous mill is a main item to distinguish SAG mill and autogenous mill. In order to eliminate the impact of the accumulation of rock, the autogenous mill allows to add about 3% of the ball (Φ80 ~ Φ120), SAG mill steel ball filling is generally 8% ~ 12%, even up to 15%.
Advantages of Semi Autogenous Grinding Mill
The full range of specifications and wide range of applications enable SAG mills to perform grinding operations with fewer configurations than conventional mills. This helps to reduce the investment and maintenance costs of the SAG mill circuit.
The scope of application is wide due to complete specifications of SAG mill. The semi-autogenous mill can be equivalent to two or three stage crushing and screening, rod mill, and part or all of the ball mill grinding operation effect.
SAG mill is also the best solution for wet grinding. In this regard, the crushing and screening process is difficult to complete.
