Ball mill grinding machine for rock ore powder making
The ball mill is the key equipment for grinding the material to powder after it is crushed. It is suitable for grinding various ores and other materials, is widely used in mineral processing, building materials, chemical industry and other industries. It uses the steel balls as the grinding medium, and achieves fine grinding of the materials through mutual impact and grinding between the steel ball and materials. According to different grinding methods, it can be divided into two types: dry and wet. And according to different discharge methods, it can be divided into two types: grate type and over fall type.
Working princple
The ball mill grind machine is composed of feeding part, discharging part, rotating part, transmission part (reducer, small transmission gear, motor, electric control) and other main parts. The motor drive the speed reducer, the speed reducer drive the small gear, the small gear drive the big gear, the big gear drive the rotary body moving. The material enters from the feeding mouth, and ground into powder by the impact of steel balls and ore and self-grinding. There is a grate at the discharging mouth (at the big gear) for filtering. Due to continuous feeding materials, the pressure pushes the material to the discharging mouth, the small particles go out from the grate to the discharging mouth, and the big particles continue to grind. The ore pulp surface in the cylinder is low, which reduces the over-grinding of ore and prevents the steel balls from falling out. Under the same production conditions, the production capacity of the grid mill is greater than that of the overflow mill. Rolling bearings are used at both ends of the cylinder instead of sliding bearings, which is more energy-efficient.
Advantages
Ball mill has many significant advantages. It has strong material adaptability, can process various ores and materials, can be continuously mass-produced, and can meet the needs of modern industry. It has a large crushing ratio, and is easy to adjust the product fineness and uniform particle size. It can adapt to dry and wet production, and can also combine drying and grinding. It has a simple structure, reliable operation, can run continuously for a long time, and is easy to maintain and manage. In addition, it has a good sealing device to prevent dust from flying, and is environmentally friendly.
