Comparison of Comminution by Impact of Particle …

Experiments were carried out in a Pulsar, a cross beater mill and a ball mill for comparison purposes. The results show that, for the material quartz sand, grinding in the Pulsar at a medium pressure of compressed air ( p car,i = 7.5 bars) and a medium magnetic valve opening time ( t o = 70 ms) is as efficient as in the ball mill.

Based on an nth order model of the grinding process, the theory is also applied to the calculation of suitable ball media composition for an industrial continuous mill. The change in ball media composition as calculated using the model, results in a 20% increase in production from an industrial mill.
