Name: Ball Mill， vibrating ball mill， ball mill mining， ball mill crusher,Ball mill grinder
Loading capacity: 1.5-338T
Feed particle size: ≤25mm
Production capacity: 0.17～170t/h
Uses: Widely used in cement industry, new construction industry, ferrous and non-ferrous metal beneficiation, glass ceramics and other production industries.
Structure: The ball mill consists of the feeding part, the discharging part, the rotating part, the transmission part (reducer, small transmission gear, motor, electric control) and other main parts.
For the material to be crushed and then crushed, the ball mill grinder is the key equipment. Cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation, glass ceramics and other production industries use it for dry or wet grinding of various ores and other grindable materials. Various ores and other materials can be ground in ball mills. They are used widely in the mineral processing, building materials, and chemical industries. Dry grinding and wet grinding are the two major types. They can be divided into two categories based on how they discharge: lattice type and overflow type.
- Reliable operation and smooth operation. Ball mill maintenance downtime is reduced and efficiency is enhanced.
- Steel is cast into the hollow shaft, the inner lining is removable and replaceable, the large rotary gear is honed by casting, and a wear-resistant lining plate is incorporated into the cylinder.
- Dry ball mills and wet grid ball mills can be selected based on the material and discharge method.
- Traditionally, ball mills use rolling bearings instead of bearing bush sliding bearings, which can reduce energy consumption by 10%-20% and reduce costs for users.
- Drum feeders and combined feeders are available to suit the needs of different working conditions. This grinding equipment is low-cost and high-performance.
On both sides of the cylinder body are end caps with hollow journals, and the journals of the end caps are supported on bearings. The appearance of the ball mill grinder is a lying long cylinder. The cylinder is filled with grinding media, such as steel balls, ceramic balls, etc. There should be a reasonable distribution of large and small balls in the cylinder, and the amount of balls loaded should be 40-50% of the effective volume.
A hollow shaft at the feed end of the ball mill grinder loads material into the barrel when working. As the ball mill barrel rotates, the grinding body is attached to the barrel liner and taken away by the barrel as a result of inertia, centrifugal force, and friction. As it is brought up to a certain height, it is thrown down by its own gravity, and the falling grinding body crushes the material in the cylinder just like a projectile. Through the feeding hollow shaft, the material enters the first chamber of the ball mill uniformly and spirally.
The chamber is lined with a stepped or corrugated lining plate, and steel balls of different specifications are installed inside. A rotation of the cylinder generates centrifugal force, which lifts the steel balls. The steel balls fall, pound, and grind the material. As soon as the material reaches the rough grinding in the first warehouse, it enters the second warehouse through a single-layer partition board. The warehouse is lined with a flat plate and has steel balls to grind the material further. In order to complete the grinding process, the powder is discharged through the discharge grate.
- High wear resistance and impact resistance (lining plate)
During the advanced double-medium quenching process, the lining plate can withstand huge impact forces in production, and can maintain its surface shape for a long time during operation, thereby reducing its deformation and wear.
- The lining plate has strong adaptability
When compared with high manganese steel liners on the market, the medium alloy double medium quenched medium alloy steel ball mill liners show higher cost performance and can be adapted to wet, dry, or mixed grinding of various ores and rocks.
- High bending strength of gears (gears)
Using displacement gears in ball mill accessories can eliminate the phenomenon of undercutting, strengthen gears with weak bending strength, and increase the bending strength of the gear teeth by more than one time.
- Heat insulation and cooling, long life (bearing)
By enlarging the diameter of the hollow shaft of the ball mill’s rolling bearing, the radial distance between the bearing and the feeding and discharging screw cylinder is increased, which contributes to heat insulation and cooling, thus prolonging the bearing’s service life.
- Heat insulation and cooling, long life (bearing)
Increasing the diameter of the hollow shaft of the rolling bearing part of the ball mill allows the radial distance between the bearing and the screw cylinder to be longer, which plays a role in heat insulation and cooling, and prolongs the bearing’s service life.
- Energy-saving and consumption reduction, less wear and tear
In lieu of grease lubrication, thin oil lubrication prevents poor lubrication due to lack of oil, reduces friction coefficients of bearings and other components, and greatly reduces wear rates of components.
