In this paper, based on the noise signal, BBD ball mill material detection method and mill pulverizing system optimization control are presented. The noise of ball mill is decomposed using wavelet packet. The eigenvectors reflecting coal level of mill can be obtained from wavelet packet parameters. Through neural network training, the statistical model of coal level and ball mill eigenvectors ...

The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.

This tendency of the noise level is justified by the buffer effect of an increasing load on the interaction of particles. At low material filling level, balltoball impacts predominate. Since these interactions have high restitution coefficients, then high force pulses will be translated into high torque pulses on the mill geometry.

The toe angle was inversely proportional to ball filling, but the impact point angle was appeared to invariant to ball filling and inversely proportional to mill speed. By means of motion analysis of the charge, a good grinding efficiency can be obtained when the ball filling ranging from 20% to 40% and the mill speed ranging from 70% to 80%.

Sound level detector; Sound level detectors are used to control the mill filling. The mill makes a deader and quieter noise as the quantity of material in the compartments increase. If the sound pressure emitted decreases from the normal operation value, the supply of fresh feed must be throttled. Bucket Elevator KW (HP)

Grinding in Ball Mill Common Issue: First chamber loading and consequently jamming if not attended soon. It happens due to number of reasons and the most common reasons are periodic size change from feeding hopper, feed moisture change or lack of hot air at normal feed rates. Symptoms: Mill sound level decreasing or loading increasing.
