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.

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)

Zhang (2001) studied the fill level by measuring the energy consumption of the mill motor, but the wear of steel balls and the variation of ball load can seriously affect the power value of the mill. Kolacz (1997) proposed a method to measure the fill level by using a strain transducer.
