Abstract. Double roll crushers (DRC) have the highest throughputs among primary crushers. In the oil sands, the hourly capacity may exceed 14,000 t/h. They are preferably used to comminute medium-hard rock or sticky materials. An unusual tough particle or unbreakable object may effect substantial dynamic forces in a DRC.

Roll diameters vary from 0.5 m to 2.8 m, and roll widths vary from 0.2 m to 1.8 m. The recom-mended maximum L/D ratio for hard ores is 0.7:1. The L/D ratio has a very important effect on the properties of the mechanical components, layout of the drive system, performance of the rolls and wear life of the liners. Capacities vary from 20 to ...

Selecting the proper Roll Crusher for an application depends on many factors. When selecting the proper Roll Crusher for an application, you must fully consider all the components of the crushing process. There are numerous factors to be considered, such as: Material to be crushed. Feed size. Product size.
Working concept. Magaldi Single-Roll Crusher features a toothed roll assembly, which crushes the incoming feed material against anvil plates. When the material enters through the inlet chute, the teeth of the rotating cam shear and split the chunks against the anvil plates. The crushed material is cleared and dropped down, through the crusher ...
