Double toggle movement jaw crushers like the Blake style (named for the inventor of the first successful mechanical jaw crusher, Eli Whitney Blake), have long been the standard used for crushing hard and abrasive rocks, as well as sticky feeds. These jaw crushers have high energy efficiency. The overhead pivot design further reduces wear and ...
Whereas in Blake crusher [figure (b)] movable jaw is pivoted at the top of the V-shape. Therefore, the greatest amount of motion is at the bottom of V, which means that there is a little tendency for a crusher of this kind to choke, though this may permit some uncrushed rock to pass through. Capacity of Blake crusher is more than Dodge crusher.

March 28, 2019 / in News. A jaw crusher is a large piece of equipment that's used in mine and ore processing plants to crush rocks. The equipment was first introduced back in 1858 by inventor Eli Whitey Black who primarily developed machinery used for crushing stone. From there, jaw crushers have seen plenty of action in the pit and quarry ...
The Working Principles Of A Jaw Crusher. All jaw crushers operate on the same straightforward principle; two hard-faced heavy plates or jaws crush large particles between them. One powered jaw reciprocates in an elliptical motion opposite a stationary jaw mounted in the frame. During an operating cycle, the gap between the two jaws opens; a ...

SIZE REDUCTION 1. A material is crushed in a Blake jaw crusher such that the average size of particle is reduced from 50 mm to 10 mm with the consumption of energy of 13.0 kW/ (kg/s). What would be the consumption of energy needed to crush the same material of average size 75 mm to an average size of 25 mm : a) assuming Rittinger's law applies?
Blake's design, which utilized a toggle linkage construction, was known as the Blake Jaw Crusher. Blake's crusher was announced in 1857 and patented in 1858. Perhaps surprisingly, the same basic design is still in use today for rock crushers. In the years following the design of the Blake Jaw Crusher, another type of crusher was designed.
Blake Jaw Crusher. The steam shovel began to change the entire picture of open-pit working. With the steam shovel came the really ''huge" No. 8 crusher, with its 18″ receiving opening. Up to this time the jaw crusher had kept pace with the gyratory, both from the standpoint of receiving opening and capacity, but now the gyratory stepped ...

A comparison of jaw crushers with the same capacity reveals that double-toggle jaw crushers are more expensive than ordinary jaw crushers. For this reason, mostly single-toggle jaw crushers are used in the aggregate sector, while double-toggle jaw crushers are used mostly for crushing very hard and highly abrasive materials.
a jaw crusher. THEORY: Crushers are slow speed machines for coarse reduction of large quantities of solids.
