Figure 5.1 Schematic diagram of a crusher showingg the open- and closed-side settings. 5.1 Jaw and Gyratory Crushers. Jaw and gyratory crushers are used mostly for primary crushing. They are characterized by wide gape and narrow discharge and are designed to handle large quantities of material. The capacity of the crusher is determined by its size.
From Allis-Chalmers' Superior Primary and Secondary Crushers. ° Actual required depends on stone hardness, reduction ratio, and so on. If a 60-in. gyratory crusher is to process material from a quarry where a shovel loads the raw material, the shovel would probably have to have a dipper capacity of at least 5 cu yd to be compatible.

They're also popularly known as the "Blake type" because of their similar mechanism to the original jaw crusher by Eli Whitney Blake. For a long time, this has been the standard for breaking abrasive and hard materials, having been used for over a century. This variation has a higher energy-efficiency as well as a longer useful life.

A jaw crusher is a robust, essential and rugged crusher used primarily in mining and construction for the initial crushing of large rocks and ore. Positioned at the start of the crushing process, it uses …
A jaw or toggle crusher consists of a set of vertical jaws, one jaw being fixed and the other being moved back and forth relative to it by a cam or pitman mechanism. The jaws are farther apart at the top than at the bottom, forming a tapered chute so that the material is crushed progressively smaller and smaller as it travels downward until it ...

Crushers. Barry A. Wills, James A. Finch FRSC, FCIM, P.Eng., in Wills' Mineral Processing Technology (Eighth Edition), 2016 Jaw-crusher Construction. Jaw crushers are heavy-duty machines and hence must be robustly constructed. The main frame is often made from cast iron or steel, connected with tie-bolts. It is commonly made in sections so that it can …
For example, a 32 x 54 sized jaw crusher will measure 32 inches from the movable to stationary jaw (when measured at the top i.e. the opening), and each jaw will have a 54-inch width. If a jaw crusher is rated by jaw plate size, a suitable rating maybe 600 x 400, which indicates a 600 mm by 400 mm jaw plate dimension.
The jaw crusher's working principle is based on the reciprocatory movement of the fixed and movable jaw plates. These plates move in opposite …
