Jaw crusher Advantages. Optimize the crushing cavity type to make the stroke at the bottom of the crushing cavity larger, the material handling capacity is stronger, and the crushing efficiency is greatly improved. Modular design is adopted to save time and installation cost, and minimize on-site construction work.

The jaw crusher is primarily a compression crusher, while the others operate primarily by the application of impact. 4.2. Design of Jaw Crushers. Jaw crushers are designed to impart an impact on a rock particle placed between a fixed and a moving plate (jaw). The faces of the plates are made of hardened steel. Both plates could be flat or the

In this paper, a model of a jaw crusher with two movable working bodies—jaws, which oscillations are excited by two self-synchronizing unbalance vibro-exciters, rigidly fixed on them, is considered. Both jaws are modeled by solids of the same mass, which are attached to a frame by elastic elements with the same linear characteristics. The frame is modeled by a solid with the mass greater

In this article we investigate the dynamics of an inclined vibratory jaw crusher, in which oscillations of the jaws are excited only by one inertial vibration exciter, located on the upper jaw. The laws of forced oscillations of the jaws are obtained. The conditions for existence of the symmetrical form of forced oscillations (an ideal operating mode of the crusher) are introduced.

All jaw crushers feature two jaws: one of which is fixed while the other moves. The working principle of jaw crushers is based on the reciprocating movement of the movable jaw that compresses and crushes the rock or ore between itself and the fixed jaw, as the material enters the zone between the jaws.

Jaw crusher: The material is crushed between a fixed jaw and a mobile jaw. The feed is subjected to repeated pressure as it passes downwards and is progressively reduced in size until it is small enough to pass out of the crushing chamber. This crusher produces less fines but the aggregates have a more elongated form.
