Laboratory-scale validation of a DEM model of a toothed …

A discrete element method (DEM) model of the crushing process of a toothed double-roll crusher (TDRC) is established using the bonded particle model. DEM results and experimental data are compared quantitatively and a relatively good agreement is observed. The effects of rotation speed and structure of crushing rolls on the performance of TDRC are …

Cone Crusher Operating Variables

The material was fed to the crusher at a rate which would either utilize the total horsepower available or fill the crusher cavity. Normally, the horsepower was the limiting factor with the ¼ (6.35mm) and 3/8 inch (9.53mm) settings while the cavity capacity was the limiting factor at closed side settings above the 3/8 inch (9.53mm) value.
