Dust Removal Measures for Energy-saving Ball Mills

Compared with the traditional ball mill, the energy-saving ball mill adopts a sliding bearing bush, which has large frictional resistance and high power consumption. According to statistics, the loss of friction power accounts for about 17% to 23% of the motor power. New energy-saving ball mills generally use rolling bearings instead of bearing bushes, and the frictional power consumption of the main bearings is reduced by more than 90%, achieving energy saving expectations.

The energy-saving ball mill is suitable for grinding various ores and other materials. It is widely used in mineral processing, building materials and chemical industries. It can be divided into dry and wet grinding methods. According to different mining methods, it can be divided into two types: grid type and overflow type. The energy-saving ball mill is an efficient grinding machine in the ball mill equipment. The energy-saving ball mill is the most used grinding and mixing machine for customers today.

First, measures to remove dust from energy-saving ball mills

1.Insulation measures. Whether high-voltage electrostatic precipitators can be used successfully in winter, insulation measures are the most important, especially the insulation in the electric field is more critical. Therefore, the energy-saving ball mill dust collector of our factory adopts double-layer shell, filled with expanded perlite, with a thickness of l00mm, and the heat preservation effect is better.

2. The concentration of dusty gas. The energy-saving ball mill high-voltage electrostatic precipitator treats the concentration of dust-containing gas, and the upper limit is generally 40g/m3. When the dust-containing gas concentration exceeds this value, the dust collection efficiency will be greatly reduced. Therefore, in the design, if the concentration of the dust-containing gas is high, the secondary dust collection process should be considered. The first stage uses cyclone dust to remove the dust, and the second stage uses high-voltage electrostatic dust to remove dust.

3. Normal use of the cleaning device. The ashing should not be frequent, and the number and time of slamming can be determined according to the dust adsorption situation and the voltage and current drop. Under normal circumstances, try to reduce the number of rapping to reduce the secondary dust.

4. Energy-saving ball mill high-voltage silicon rectifier transformer placement, should be equipped with high-voltage shielding room (at least should be set up a safety fence), both safe and in line with technical requirements. At the same time, try to make the transformer close to the cylinder of the high-voltage electrostatic precipitator to reduce the loss of secondary voltage and current.

5. When the high-efficiency electrostatic precipitator is deactivated in the energy-saving ball mill, the high-voltage electrical control box should be stopped for 10 minutes later than the mill. The hot and humid gas in the electric field area is discharged to the dust remover, so that the corona pole and the shell metal material are reduced in corrosion, and the cement ball mill can simultaneously discharge the dust gas to the standard.
