Product Details
Autogenous mills and semi-autogenous mills are two important pieces of equipment in the mineral processing industry. Here is a brief introduction to both:
Autogenous Mill
An autogenous mill, also known as a mill without grinding media, is a new type of grinding equipment that combines both crushing and grinding functions. It uses the material being ground itself as the grinding media, achieving crushing through mutual impact and grinding. According to different ore grinding methods, autogenous mills can be divided into dry and wet types. Currently, wet autogenous mills are widely used in China. Autogenous mills can grind materials to 0.074 mm in a single pass, with the content accounting for more than 20%~50% of the total product, and the crushing ratio can reach 4000~5000, which is more than ten times higher than that of ball mills and rod mills.
Semi-Autogenous Mill
A semi-autogenous mill is a mill that requires grinding media (such as steel balls or steel rods) to crush the material. Its working principle is to put ore and a small amount of steel balls into the mill cylinder, and through the rotation of the cylinder, the ore and steel balls collide and rub against each other to achieve the purpose of crushing the ore. Semi-autogenous mills have advantages such as high crushing ratio, good reliability, strong adaptability, and large processing capacity, and are widely used in mineral processing, metallurgy, construction, and chemical industries.
In general, autogenous mills and semi-autogenous mills are both important equipment in mineral processing. They each have unique characteristics and advantages, and the choice should be based on specific needs in practical applications.
The company can produce autogenous mills and semi-autogenous mills of various specifications and models with diameters below 10m. They are widely used in the grinding operations of black and non-ferrous metal ores and non-metallic ores, and are particularly suitable for processing useful minerals with medium-hardness or below and rocks with coarse and uniform grain embedding.
