Ball mill energy saving tips

As is known to all, ball mill is the key equipment in dressing plant, its energy consumption is the largest of the mill plant, accounts for about 50% of the entire plant energy consumption. In todays demanding society, energy saving and emission reduction to reduce energy consumption of ball mill is imperative. Yantai xinhai mining machinery co., the technical personnel after years of ball mill research summarizes several ways to reduce energy consumption of ball mill:

Energy-saving ball mill

1, the lattice type ball mill instead of the overflow type ball mill

Grid type ball mill than the overflow type ball mill not only has low row ore mouth pulp surface, pulp by fast speed, can reduce the ore crushing, holds the ball more, can be mounted ball, you can also use the balls at the same time, due to the row of ore terminal is equipped with grid, ball will not be pulp out of the barrel, and can form good working conditions. And grate type ball mill is higher than the same specification of the overflow type ball mill production by 20% ~ 30%, and can save power by about 25%.

2, rolling bearing instead of sliding bearing

Overcome rolling rolling bearing low friction coefficient, ball mill rolling bearing frictional resistance required power consumption is lower than sliding bearing. Rolling bearing in normal working conditions at the same time, the main bearing of 10 years without replacement, save overhaul, maintenance costs, improve the operation rate of ball mill.

3, adopt pneumatic clutch to replace the ordinary clutch

Pneumatic clutch can successfully implement segmentation starting synchronous machine, ball mill, and can make motor no-load starting, to achieve stable operation speed, and to integrate the clutch starting ball mill. This can make the motor itself starting time, starting easily, reduce the starting current of the impact of the Internet, also reduce the ball mill equipment installed power.

4, with rubber lining

Rubber lining board is a kind of high wear-resisting performance non-metallic materials, practice shows that wet grinding machine with rubber lining, mill unit may generally lower energy consumption, reduce about 10%, production capacity increases by about 5%. In addition to the service life of rubber lining generally about 2 ~ 3 times of alloy plate, it is worth mentioning that Yantai Xinhai wear-resisting rubber industry co. Use wet formula design, combined with the performance of the dispersion of nano composite technology is excellent wear-resisting rubber, excellent wear resistance, its service life is 3 ~ 4 times of ordinary rubber.

In addition, there is a kind of the method can reduce the energy consumption is to use a new type of ball mill, xinhai ore independent research and development of ultrafine laminated since mill, than ordinary ball mill energy consumption can reduce by 60%, its basic reason lies in the mill row ore mouth in the lower row of ore block, so that the ore pulp of buoyancy, ore crushing each other, is worthy of the name and energy-saving grinding equipment.
