Liberation characteristics of coal middlings comminuted by jaw crusher …
Full densimetric analyses indicate that mineral liberation of the product crushed by the jaw crusher is better than that by the ball mill at each fraction. For sizes of −0.125 mm + 0.074 mm and −0.074 mm, yields of the product with ash content 11% comminuted by jaw crusher are nearly 20% higher than that by the ball mill.
Crushing Chamber
For a jaw crusher the thickness of the largest particle should not normally exceed 80–85% of the gape. Assuming in this case the largest particle to be crushed is 85% of the gape, then the gape of the crusher should be = 45.7/0.85 = 53.6 cm and for a shape factor of 1.7, the width should be = 45.7 × 1.7 = 78 cm.

The effect of rock crusher and rock type on the aggregate shape
The jaw crusher is usually used as a primary crusher [22]. For reducing the rock blocks into 4–5 cm particles and having the same crushing for all samples before the last crushing, the samples were crushed by JC. Then, rock samples were crushed by two rock crusher according to the typical crusher in Iran, i.e., JC and HSI.

Fractal evaluation of particle size distributions of chromites …
The jaw crusher is primarily a compression crusher and similar to jaw crushers, the mechanism of size reduction in cone crusher is primarily by the compressive action of two pieces of steel against the rock (Gupta et al., 2006). The force is applied slowly (in comparison to impact machines) resulting in abrasion and cleavage fracture. ...
