Products. Maximise the productivity of your operation with durable high-efficiency Semi Autogenous Mill (SAG mill) and Autogenous Mill (AG Mill).
Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon. SAG mill: When the weight of the SAG mill is more than 75%, the output is high and the energy consumption …
A SAG mill, or semi-autogenous grinding mill, is a type of machine used in mining and mineral processing operations. It uses the crushing and grinding action of rocks to reduce materials such as copper ore into smaller pieces for further processing. Unlike traditional mills that rely on steel balls or other media to break down materials, SAG ...
A ball mill consists of various components that work together to facilitate grinding operations. The key parts include the following: Mill Shell: The cylindrical shell provides a protective and structural enclosure for the mill. It is often made of steel and lined with wear-resistant materials to prolong its lifespan.
Current operational results show that the SAG mill is operating at 5% ball charge level by volume and is delivering a K80 800 micron product as predicted. Power drawn at the pinion is 448 kW, 13.617 kWh/tonne (SAG mill) and 570 kW, 17.325 kWh/tonne (ball mill) when processing 32.9 mtph, for a total of 30.942 kWh/tonne or …
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%.
Within comminution circuits, High Pressure Grinding Rolls (HPGR) are increasingly replacing conventional SAG, rod and ball mills for hard rock reduction – owing to their substantially lower energy consumption and potential for significant total cost of ownership reduction. Not only do they require as much as 40% less energy than traditional …

The main difference between a ball mill and a SAG mill lies in the size of the mill chamber. In a SAG mill, balls of up to 150mm in diameter occupy 5%-18% of the mill chamber volume. In contrast, a ball mill contains grinding media up to 50mm in diameter, occupying between 25% - 40% of the mill chamber volume.

Semi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These
