Ball mill

Ball mill

Ball mill is a kind of equipment for grinding ore and other materials to obtain satisfactory product granularity.

The ball mill is mainly composed of the feeding department, the feeding department, the main bearing department, the simplified tube department, the driving department, the discharging department and the main motor. Motor through the gear drive and slow down, drive mill simplified simplified placed at the appropriate speed rotation of the grinding medium under the action of centrifugal force, friction force and gravity, was promoted to a certain height, a throw up or falling state, in the simplified material impact by the medium and the break, at the same time, due to the rolling or sliding medium, make the material be crushed by grinding strip effect. The ground material is discharged through the outlet. According to the need, the mill can be equipped with air clutch, slow drive device, jacking device, jet lubrication device. The main bearing of the ball mill can be used as plain sliding bearing, static bearing, static bearing and rolling bearing.

According to the needs of the ball mill can use magnetic village board, magnetic village board than metal lining board thin, light weight, long life, can reduce energy consumption, improve output, magnetic village board is generally applicable to the second stage mill. Our company can design and manufacture many kinds of mill according to customer's requirement.

Structure:

Wet grid ball mill

[product introduction] :

The utility model relates to a traditional ball mill which relies on the grid to discharge ore.

[barrel diameter] :

900 mm to 4500 mm

[application scope] :

The wet grid ball mill is often used to grind coarse ore.

[product improvement] :

The cylinder of wet grid ball mill can be used with high wear-resisting rubber liner, which has good wear resistance, long service life and easy maintenance.

[advantages and features]

Jacking device for easy maintenance;

Static and dynamic pressure bearing, stable and reliable operation;

Slow transmission, easy to repair and start;

Oil mist lubrication device to ensure reliable lubrication of large and small gears;

The air clutch starts flexibly.

【 working principle of wet grid ball mill 】

It is mainly through the transmission device to make it slowly rotate, materials from the barrel feed end into, in the barrel due to the steel ball and ore itself dropped impact and self-grinding, materials can be crushed. As the material is fed continuously, its pressure causes the material in the cylinder to move from the feeding end to the discharging end. The material reaching the finished product size is discharged from the barrel discharge end. When wet grinding, the material is carried out by water flow; When dry grinding, the material is carried out by airflow. The mill has a discharging grid at the discharging end. The mill relies on the grid plate to force the discharging of ore. The pulp surface in the cylinder is low, which can reduce ore over-grinding and prevent steel balls from discharging.

Wet overflow ball mill

[product introduction] :

The utility model relates to a ball mill with simple structure and relying on slurry to discharge ore.

[production capacity] :

0.17 ~ 170 t/h

[application scope] :

This wet overflow ball mill is often used to grind fine ore.

[product improvement] :

Wet-overflow ball mill cylinder can be used with high wear-resistant rubber liner, with good wear resistance, long service life and easy maintenance.

[advantages and features]

Jacking device for easy maintenance;

Static and dynamic pressure bearing, stable and reliable operation;

Slow transmission, easy to repair and start;

Oil mist lubrication device to ensure reliable lubrication of large and small gears;

The air clutch starts flexibly.

[working principle of wet overflow ball mill]

The main component is a cylinder with a small diameter and a large length, which is supported by rolling bearing. It is slowly rotated by transmission machinery. Materials are fed from the feeding end of the cylinder. As the material is fed continuously, the pressure causes the material in the cylinder to move from the feeding end to the discharging end, and the slurry overflows from the lower edge of the hollow shaft at the discharging end. Hollow shaft with anti-spiral blade can return the overflow steel ball and coarse ore block to the mill.
