high energe saving ball milling machine application
The ball mill is a commonly used crushing equipment, which is mainly used for crushing, mixing and dispersing various materials stored in the warehouse. The following is the working principle of the ball mill:
high energe saving ball milling machine Components
The ball mill mainly consists of the following parts:
Cylinder: a horizontally placed cylinder with grinding bodies (such as steel balls) inside.
Hollow shaft for feeding and discharging materials: used for feeding and discharging materials.
Grinding head: auxiliary equipment to help materials enter and discharge.
Grinding body: usually steel balls, but can also be other materials such as ceramics, stone, etc., selected according to the particle size of the grinding material

Material entry: the material enters the first bin of the mill evenly through the hollow shaft spiral at the feed end.
Preliminary crushing: in the first bin, due to the rotation of the cylinder, the grinding body will be attached to the inner wall of the cylinder due to inertia and centrifugal force, and will be brought to a certain height. When its gravity exceeds the centrifugal force, the grinding body will fall, impact and grind the material to achieve the effect of coarse grinding.
Further grinding: the material after preliminary crushing enters the second bin through a single-layer partition plate, which is equipped with a flat lining plate and a steel ball of smaller diameter to further grind the material.
Finished product discharge: The powder that finally reaches the required particle size is discharged through the discharge grate plate, completing the grinding operation

Grinding mechanism
Impact effect: When the cylinder rotates, the grinding body is brought to a certain height and then falls down, crushing the material in the cylinder like a projectile.
Friction effect: During the rotation of the cylinder, the friction between the grinding body and the inner wall of the cylinder and between the grinding bodies will also produce a grinding effect on the material.
Sliding effect: During the rotation of the cylinder, the grinding body will slide down, and the sliding process will also give the material a grinding effect
how to enlarge life of high energe saving ball milling machine
1. Wide application range: suitable for grinding various ores and other materials, widely used in mineral processing, building materials and chemical industries.
2. Various grinding methods: can be divided into dry and wet grinding methods, which can meet the needs of different materials and production processes.
high energe saving ball milling machine features
Ball mill accessories include: ball mill liner, ball mill steel ball, ball mill gear, ball mill coupling, ball mill partition plate, ball mill manganese steel liner, ball mill wear-resistant liner, ultra-fine mining ball mill liner, ball mill screen plate, etc. Among them, those that are easy to damage are called energy-saving ball mill wearing parts.
Generally, the ball mill needs to have a greater impact force to deal with hard and coarse ore. At this time, larger steel balls need to be loaded, that is, the harder the material, the larger the diameter of the steel ball.
Generally, according to the fineness of the ball mill material feed and the mill diameter, as well as the slurry concentration, liner and many other conditions, generally, the first stage mill is based on 3 to 4 types of steel balls such as 100 80 60, and the second stage can be 60 50 40 30. The actual proportion needs to be subdivided according to your material conditions.
Steel balls can be divided into cast steel balls and forged steel balls according to their production process. Generally speaking, cast steel balls are suitable for dry grinding, while forged steel balls are suitable for wet grinding. Under normal circumstances, the diameter of steel balls in ball mills is between 20-125mm, and they are divided into large balls, medium balls and small balls. However, the diameter of steel balls used in super large ball mills can reach 130-150mm.
