Jaw crushers use mechanical pressure to break the material by forcing it between two vertical jaws, one stationary and one that is driven back and forth. The gap between the two jaws narrows as the material moves through the crusher, further reducing the size. Jaw crushers are heavy duty machines and can be used in mining or quarry …

Introduction. Gyratory cone crushers have been in use for over a century, with the first models dating back to the late 1800s. They were initially designed to handle larger feed sizes and higher capacities than jaw crushers, which were the most common crushers used at the time. Over the years, gyratory cone crushers have evolved into …

The stone crusher plant consists of a crushing setup of excavators, feeders, primary and secondary crushers and screeners. They all work together to crush stone as efficiently as possible. Conveyors connect everything, moving the crushed material from one station to the next. Stone crusher plant equipment is divided into two categories:

Crushers of this type are more suitable for the reduction of hard to medium hard material fed in smaller lumps. Jaw crushers are sensitive to moist and plastic feed material and tend to choke if there is a substantial proportion of fine particles in the feed. The attainable reduction ratio is between about 6:1 and 8:1.

Jaw crushers use a pair of opposing jaw plates set in a V, at the base of which is an opening for crushed material to fall through. Because of the spacing of the jaw plates, the large pieces are crushed at the top of the plate, and become progressively smaller as they fall downward. This causes the finely crushed pieces to exit the system …
