The large pieces of dolomite are transported by special vehicles to the feeder, and then sent to the jaw crusher by the conveyor for coarse crushing and crushed into smaller-sized particles. The jaw crusher has large feeding particle size, large crushing force and crushing ratio, wide application range and many materials.

Cone Crushers deliver a 4:1 to 6:1 reduction ratio. A Cone Crusher with coarse-style liners would typically have a 6:1 reduction ratio, though reduction ratios of 8:1 may be possible in certain coarse crushing applications. Fine liner configurations typically have reduction ratios of 4:1 to 6:1.

The jaw crusher has large crushing ratio, which means that jaw crusher can crush large materials over 1000mm into particles smaller than 100mm. In crushing and sand production plant, jaw crusher is the preferred equipment for coarse crushing of materials with compressive strength not exceeding 320 MPa. So, if you want to process …

Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1.

Impact crusher: can crush materials with a side length of 100-500mm, and its compressive strength can reach up to 350MPa, large crushing ratio and the crushed products are cubical with uniform particle size. Impact crusher is widely used in rock crushing in highway engineering. Hammer crusher: suitable for crushing various brittle minerals.
