Discrete Element Simulation of Rock Crushing Considering

Numerical simulation was conducted to study the particle breakage of rock in rolling compaction (RC) test based on discrete element method (DEM). Different shapes of particles were formed to represent the real particle shape. A quantitative analysis method of particle breakage was proposed according to the grading curve before and after compaction.

Types of Crushers

Crushers may be divided into three general classes, with respect to the manner in which they do their work: Pressure Crushers: This category embraces the several types of gyratory crushers and jaw crushers, as well as the double crushing rolls, with either smooth or corrugated shells. Impact Crushers: This division is represented chiefly by the various styles of hammermill; also by the cage

[PDF] Discrete element modelling of a rock cone crusher

The feasibility of the discrete element method to model the performance of a cone crusher comminution machine has been explored using the particle replacement method (PRM) to represent the size reduction of rocks experienced within a crusher chamber. In the application of the PRM method, the achievement of a critical octahedral shear stress induced in a particle was used to define the breakage

Impact crushers are traditionally classified into two main types, horizontal shaft impact (HSI) crushers and vertical shaft impact (VSI) crushers. These different types of impact crushers share the crushing principle, impact, to reduce the material to smaller sizes, but features, capacities and optimal applications are far from each other.
