There are significant differences between ball mills, autogenous mills, and semi-autogenous mills in many aspects.
About of ball mill
Ball mill: uses the collision and friction between balls to grind non-ferrous metals such as ores and sand. The material enters the drum through the feeding device, and the grinding medium also enters at the same time. After the drum starts to rotate, the material and grinding media continue to collide and rub in the drum, so that the material is gradually ground into fine powder.
Ball mill: widely used in foundry, building materials, metallurgy, chemical, and other industries, suitable for dry or wet grinding of various grindable materials.
Ball mill: high grinding efficiency and reasonable internal design of the drum, which can fully mix the materials and grinding media. It can be used for dry and wet grinding to adapt to different process requirements.
About of Autogenous grinding mill
[Introduction]: A wet autogenous grinding mill that materials as grinding media
[Capacity]: 200-350mm
[Improvement]: High-efficiency autogenous mill can realize the second and third stage crushing and screening, and part or all of the crushing and grinding functions of the rod mill and ball mill
Autogenous grinding mill: The purpose of crushing is achieved by the mutual impact and grinding of materials in the grinding mill. The mined raw ore or coarsely crushed materials (the block size is generally 300-400mm) are directly fed into the mill, which can be ground to the required product particle size below 0.1mm at one time.
Autogenous grinding mill: Especially suitable for processing materials with high hardness and large particle size, especially for grinding ores, metal scraps, etc.
Autogenous grinding mill: It can save equipment such as crushing, grinding, and transportation. It has a simple process flow, small floor space, and low investment. The material is self-grinding, with a strong selective crushing effect and good product quality.
About of Semi-autogenous grinding mill
Semi-autogenous grinding mill: Add a small amount of grinding media (such as steel balls) into the grinding machine. It combines the characteristics of self-grinding and ball milling and uses friction, extrusion, and collision between grinding stones and abrasives to grind materials such as ores.
Semi-autogenous grinding mill: suitable for wet or dry grinding, grinding, and grinding of bricks, copper ore, iron ore, metallic minerals, and other materials.
Semi-autogenous grinding mill: It combines the characteristics of autogenous grinding and ball grinding. Its processing capacity is improved compared to the autogenous grinding machine, but the wear of the liner is relatively increased, and the product fineness may also become coarser.
In general, these three types of mills each have their unique working principles, scope of application, and characteristics. Which mill to choose needs to be decided based on specific production needs and technical requirements.
