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 ...
2017-4-12 · The rock particles are modelled using the Bonded Particle Model (BPM) and particle shapes are based on 3D scanned rocks. The machine geometry is based on CAD modelling and 3D scanning. The interactions between rock particles and between rock particles and the machine boundaries are modelled using contact models that determine the reaction forces.
The cone crusher concept was developed in the early 20th century and the basic layout of the machine has not changed dramatically since then. Efforts aimed at developing the
2021-8-15 · The minimum distance between the mantle and concave is defined as the closed side setting (CSS) of the cone crusher. The CSS is easily changed online in a large variety of commercial crushers; different principles of CSS adjustment are described in (Quist, 2017).The maximum distance between the mantle and concave, on the other hand, is defined as the open side setting (OSS).
