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 ...
Best suited for secondary crushing applications, cone crushers are designed to crush pre-sized materials, usually 100mm, 150mm or 200mm, depending on the size of the crusher. Cone crushers can …
The present study falls within this topic with the aim of developing a dynamic calibration method for crusher gauges. Testing was conducted through the use of the split Hopkinson pressure bars (SHPB) to investigate the mechanical behavior of the crusher gauges at different high strain rates. First of all, the stress/strain behavior was ...
