Jaw Crusher will Be on a Par with Tertiary Grinding Machine

The functions of tertiary grinding machine and jaw crusher are roughly the same. The only difference lies in the grinding effect of the two. Generally, the material getting into the jaw crusher will be crushed mainly by extrusion and impact; however, grinding machine relies on centrifugal force and friction to exert attack, extrusion, cutting and grinding to material.

Within the conventional crushing range, the energy consumption varies little with the particle size decrease. Nevertheless, as to grinding mill, its energy consumption sharply increases with the change in particle size. This may be due to the non-selectivity of crushing force in the process of grinding. The crushing ratio is beyond the power consumption of the mill and the medium in the body. Although the material flows to the discharge port generally, single particle may not be crushed fully while finished product can sometimes not be discharged timely, which increases the power consumption.

The material lingering may play a protective role to coarse particles, which hinders the normal operation of the working process. More crushing and less grinding can narrow the particle range. Since there is not much difference in the granularity and the diameter is small, over-grinding is prevented to some extent. Consequently, the grinding efficiency is greatly increased and power consumption reduced.
