The analysis will concentrate on jaw crushers as typical and widely used comminution process equipment. A jaw crusher (see Fig. 2) is a comminution device 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.

2.2. Samples analysis after comminution2.2.1. Particle size distribution. The gold ore sample of 200 kg was first fed to the primary crusher (PEX-150 × 250 mm) and secondary crusher (XPC-60 × 100 mm) to ensure all the sample could pass through a sieve of 20 mm.The comminuted ore was then thoroughly mixed and divided, fed to the …

The design of the swing jaw plate is proposed using point-load deformation failure relationships along with interactive failure of rock particles as a model for such a reduction in deflection value. Traditionally, stiffness of swing plates has not been varied with changes in rock strength. Rock strength has only been of interest because of the need to know …
Details
The output fragments of the jaw crushers are then fed to conical crushers and impact crushers depending on the desired products. Two different crushers are used for primary crushing. One of the crushers is coded as K07 with the sizes of 1100×850 and the other is K11 with the size of 1300×1100.
