Enterprises produce jaw crushers in various sizes: [3,4]. Classification of jaw crushers is carried out on character of movement of the moving jaw which is the basic working body of a crusher. …
Jaw Crusher is a basic sample preparation unit and is essential to address all primary size reduction requirements. Desired crushing takes place when fed particles experience stress and the compressive pressure exerted by the jaw blade toggling action exceeds its fracture stress. By this action the feed particles are crushed to smaller sizes.
This ratio can be used as a criterion for the comparison of different jaw crusher mechanism designs, with a view to selecting the most suitable design for use in a given application. 2. Literature Review. Over time, several authors have addressed the static force analysis of the double toggle jaw crusher mechanism.
The modular jaws of the developed dual pivoted jaw crusher allows flexible selection of jaw geometry, which is independent of the selectable compressive and sliding movements of the jaws.

Jaw crusher is a kind of size reduction machine which is widely used in the mining and aggregates industry. The interaction between jaw plates and material particles brings the inevitable and serious wear to the jaw plates during the jaw crusher operation, which not only decreases the efficiency, but also increases the cost and the energy consumption of the jaw …
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.
The plate dimensions of the un-optimised jaw crusher were modelled using ANSYS Design Modeller 2021, as shown in Fig. 3.The load and boundary conditions for the …
