The method of reducing the noise of Ball Mill

1, properly install gear

The gear collision of the transmission system will make noise, so in the installation process of the ball mill, special attention should be paid to the installation of the gear, and the coincidence degree, gap and modulus of the gear should be controlled within a reasonable error range. Excess error will not only cause great noise, but also may affect the operation of ball mill.

2, ball mill barrel plus sound insulation cover or damped sound insulation layer

The collision of liner plate with material and grinding medium in the cylinder will make noise, the solution is to install sound insulation cover on the cylinder body, but the sound insulation cover also has some disadvantages, it will affect ventilation and heat dissipation, and will also bring trouble to the later maintenance and maintenance. And the damping sound insulation layer avoids this kind of trouble, the concrete operation method is to make floating on the shell of the cylinder body to make the clamped damping sound insulation sleeve, with the damping sound insulation layer to carry on the bandaging to the cylinder body, can reduce the 12~15dB (A). Of the noise.

3, selection of liner

In the selection of lining plate, replacing manganese steel liner with rubber liner can reduce the impact noise of cylinder, this method is very practical, but the life of rubber liner has been discussed all the time.

4, with elastic cushion between the inner wall of the cylinder and the lining

An elastic cushion is installed between the inner wall of the cylinder and the liner to smooth the waveform of the impact force of the steel ball on the liner, reduce the amplitude of vibration of the simple wall and reduce the acoustic radiation. The noise 10dB (A) can be reduced by this method.

5. Periodic inspection of lubrication system

Check the lubrication system regularly and add lubricating oil regularly. If the lubrication work is not done seriously, the friction force of the gear will be increased and the noise will be brought about.
