Abstract. It is well known and taken for granted that the efficiency of energy use by comminution (i.e. breaking, crushing, grinding) equipment is very low, typically less than 10%. Most of the process input power is dissipated as heat and noise and ineffective deformation of the material to be processed and the device itself.

A higher value for the fines fraction ϕ in our case reflects the well-known fact that impact crushers produce more fines than cone or jaw crushers. The specific size β for the classification function (Eqs. (5), (6)) is identified as β=10 mm. The reference feed rate and impact energy per unit mass are taken to be Q 0 =1 t/h and E 0 =1 J/kg ...

Jaw plates serve a dual purpose. First, they facilitate the crushing process by compressing and breaking down the raw materials, reducing their size. Secondly, they act as guardians, shielding vital components of the jaw crusher from wear and damage. Operating Principle of Jaw Plates from M&C. 5.
