The high-efficiency and energy-saving ball mill of XKJ Group is a new type of ball mill designed according to a new concept, using special rolling bearings as the support structure of the cylinder. Its system solves the problems of lifespan and centering of heavy-duty rolling bearings used to replace sliding bearings, sealing problems under harsh environmental conditions, and cylinder displacement caused by long-term operation. Its working principle:

The energy-saving ball mill of XKJ Group consists of the feeding department, discharging department, rotary department, transmission department and other main parts. It is a horizontal cylindrical rotating device with external gear transmission, two compartments, and a grid type energy-saving grinding equipment.

The material enters the first chamber of the mill uniformly through the feeding device and the feeding hollow shaft. There is a stepped lining plate or a corrugated lining plate inside the chamber, which is filled with steel balls of different specifications. The centrifugal force and friction force generated by the rotation of the cylinder bring the grinding medium (steel balls) to a certain height and then fall, producing a heavy impact and grinding effect on the material; After rough grinding in the first chamber of the mill, the material enters the second chamber through a single-layer partition plate and undergoes fine grinding operations on the rough ground material; The ground material is discharged from the discharge grate to complete the grinding operation.

Energy saving advantages of efficient and energy-saving ball mills in XKJ Group
As the main large-scale equipment on the mineral processing production line, the energy consumption of high-efficiency and energy-saving ball mills accounts for a relatively large proportion. However, after improvement and innovation, XKJ Group's high-efficiency and energy-saving ball mills have shown significant advantages in energy conservation, as follows:

1. The starting current has been reduced to 60% of the original value, resulting in a shorter and more flexible starting time for the equipment. The working current has been reduced by 30%, achieving the effect of saving electricity.

2. Compared to ordinary ball mills, the motor power of the energy-saving ball mill of XKJ Group is reduced, the installed capacity is increased, the working efficiency is higher, and the loss of reactive power is reduced, resulting in a reduction in energy consumption throughout the production process.

3. The energy-saving ball mill of XKJ Group adopts a rolling bearing support device, which not only increases the bearing capacity, but also extends the service life of the bearings by more than 5 years, saving users production costs.

4. The use of glycerol lubrication series devices can reduce the oil consumption of oil station facilities and motors, saving up to 90% of oil; It can also slow down the heating rate of the bearings and avoid the problem of main bearing burning and shutdown due to high temperature.

5. Make full use of the surplus capacity of the motor, improve the structure of the lining plate, increase production by about 10%, and reduce average energy consumption.
