A primary crusher is designed to receive run-on-mine (ROM) rocks directly from the mines. Gyratory crushers typically crush to reduce the size of aggregate to a maximum of about one-tenth of its original size. Gyratory crushers are always installed vertically orientated. A gyratory crusher's size is classified by:

There are two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...

Electric motors will only draw as much power as the crusher needs. However, the theoretical difference in a 500,000-ton quarry or mine is about 90,000 kW/hours. That reflects only the primary crusher, not the added power it takes downstream to also recirculate 30% more rock through the secondary circuit.

For primary crushing, high-chrome blow bars are crucial. For secondary crushing, low-chrome martensitic steel is the most appropriate material. If you're using a lower-chrome alloy, you should consider white-iron bars. These are more fragile than low-chrome martensitic-steel-steel alloys. Hence, when you need to replace a blow bar, the ...
