SAG Mill

Semi autogenous grinding mill or SAG mills as they are often called, can
perform grinding operations equivalent to two or three stages of crushing and
screening. SAG mills are characterized by their large diameter and short length
as compared to ball mills. The inside of the mill is lined with lifting plates
to lift the material inside the mill, where it then falls off the plates onto
the rest of the ore charge. SAG mills are often used in grinding operations of
modern concentrators, which can directly produce particle size of finished
products or prepare feed materials for the downstream grinding sections.

Introduction of SAG Mill
Like ball mill and rod mill, sag mining 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 SAG Mill
Reduce Lifetime Costs

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.

Wide Application

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.

According to professional data sources, by far the largest SAG mill is 42'
(12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. While CIC is
currently capable of manufacturing SAG mills with a maximum diameter of 21'
(6.5m)
