Semi-autogenous grinding mill (SAG) is a highly efficient ore crushing equipment, which plays an important role in the field of metallurgy and mining processing.
What is the working principle of SAG Mill?
SAG is based on AG mill, with a certain amount of steel balls added as auxiliary grinding media. It puts ore and a small amount of steel balls into the mill cylinder together, and through the rotation of the cylinder, the ore and steel balls collide and rub against each other, so as to achieve the purpose of crushing the ore.
Features and advantages of SAG mill
1. High grinding efficiency: Due to the addition of steel balls as auxiliary grinding media, the grinding efficiency of SAG mill has been significantly improved compared with AG mill, and less stubborn stones are produced.
2. Large processing capacity: SAG mill can process a large amount of ore at one time, which is suitable for the production needs of large-scale ore dressing plants.
3. Low energy consumption: Compared with traditional ball mills, SAG mills reduce the use of steel balls during the crushing process, thereby reducing energy consumption and wear.
4. Low maintenance cost: The SAG mill has a simple structure, is easy to operate, and is relatively easy to maintain. Due to its low wear, the maintenance cost of the equipment is relatively low.
5. Wide range of applications: SAG mills are widely used in the beneficiation process of metal and non-metallic ores, especially for processing ores with higher hardness, such as copper, gold and other non-ferrous metal ores.
The typical size range of SAG mills is 7-14 meters in diameter, 4-7 meters in length, and the installed power is generally 4000-15000 kilowatts. These parameters may be adjusted according to the specific application scenario and ore characteristics.
As an efficient ore crushing equipment, SAG mill plays an important role in modern beneficiation technology. Its advantages such as high efficiency and energy saving, strong processing capacity and low maintenance cost make it one of the core equipment in the field of mining processing.
