SAG Mill

The SAG mill also known as medium-free grinding mill. The ore from the stope or the coarsely crushed ore can be directly fed into the mill. The biggest speciality of the SAG mill is that the crushing ratio is large, the input size of the grinding material is 300~400mm, sometimes even larger, and the output size can reach 0.1mm minimum, the crushing ratio can reach 3000~4000, and the inout size of ball mill is between 20-30mm, the output size is 0-3mm.

Working principle

The SAG mill is a new type of grinding equipment that combines both crushing and grinding functions. It uses the material itself as the medium to crush by mutual impact and grinding.

The SAG mill has two kinds of dragging modes: variable speed and different power fixed speed. Some SAG mills are also equipped with micro-motion devices. In order to facilitate the maintenance, there is a cylinder jacking device; for the large mill, in order to eliminate the static resistance torque at the start, a modern advanced technology such as a hydrostatic bearing is adopted to ensure the mill can operate safely.

The wet self-grinding system consists of a SAG mill, a particle size control operation, a secondary grinding equipment, and a hard-to-grain-level processing facility. Usually the mineral is fed into the mill bar at a certain ratio. The self-grinding machine can grind the material to 0.074mm at a time, and its content accounts for 20% to 50% of the total amount of the product. The crushing ratio can reach 4000~5000, which is ten times higher than the ball mill and rod mill.

Structural Features

The end cap and the cylinder are not vertically connected, and the end cap liner is tapered;

The drainage grid plate is added on the side of the discharge end, and the grinded material pass through the grid plate , then the cone cylinder sieve, material which cannot pass the seive is returned to the mill by the spiral self-return device, so closed grinding system is formed, which can further control the size of the product and reduce the amount of returning ore;
Use a mobile feeder truck for the side mine;
The girth gear is fixed on the hollow journal of the discharge end. The other part of the mill is constructed in much the same way as a dry SAG mill.
