Jaw Crusher Slideshare
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, basically, two shafts and two toggle plates. The i rst shaft is a pivoting shaft on the top of the crusher, while the other is an eccentric shaft that drives both toggle plates.Application fields. The jaw crusher is a kind of early crushing device. With simple and firm structure, reliable operation, easy maintenance and service and relatively low costs in production and construction, jaw crusher is still widely used in coarse, medium and fine crushing for various ores and rocks with compressive strengths ranging from 147 to 245 MPa in metallurgy, chemistry, building.
