Furthermore, the height of the crushed particle distribution area is H b, as shown in Fig. 7 (d), H b ≈ 0.4H f, which means that the effective crushing area of the crushing chamber is small at this condition. Here, the crushed particle distribution area refers to the area where the crushed secondary particles appear.

Calculating and Plotting Size Distributions

If the size distribution of particles from a crushing or grinding operation does not approximate a straight line, it suggests that there may have been a problem with the data collection, or there is something unusual happening in the comminution process. The size modulus is a measure of how coarse the size distribution is, and the distribution

DEM simulation of an impact crusher using the fast-cutting …

Based on the ability of FBM combined with the breakage families to predict the size distribution of the progeny particles quantitatively, a DEM simulation of a lab-scale cone crusher was conducted [23], in which all the particles are polyhedrons and the Laguerre-Voronoi tessellation method [24] was adopted to separate the particles when they ...

Crushing Principles of Mechanical Crushing

Crusher Operation • Relation between Feed size and Shape – The greater reduction ratio the worse particle shape. – Inter particle breakage improves shape. When crushing a bed of material weaker particles will break first. Flaky or elongated particles are weaker then round. – Breaking round particles gives flaky material. F l a k i n e s ...
