Reduction ratio is usually 6:1. The jaw crusher is consisting of two vertical jaws installed to a V form, where the top of the jaws are further away from each other than the bottom. One jaw is kept stationary and is called a fixed jaw while the other jaw, called a swing jaw, moves back and forth relative to it, by a cam or pitman mechanism.

The capacity of the jaw crusher available in the laboratory is 725 t/h. Jaw crushers range in size. up to 1680 mm gape by 2130 mm width. This size machine will handle ore with a maximum size. of 1.22 m at a crushing rate of approximately 725th -~ with a 203mm set. However, at crushing.

Primary Crusher Selection & Design., degradability and it being prone to dusting or not. The crusher capacities given by manufacturers are typically in tons of 2,000 lbs. and are based on crushing limestone weighing loose about 2,700 lbs. per yard3 and having a specific gravity of 2.6.
