Designs of different types of jaw crushers such as Blake, Dodge with single and double toggles used for initial comminution of minerals, as received from mines, are …
In the history of crushers, both chronologically, and by virtue of its standing in the field of heavy-duty crushing, the Blake jaw crusher stands first in the list. All of the large, heavy-duty primary crushers of the jaw type are built around the Blake principle which, for simplicity and brute strength, is unsurpassed by any mechanism thus far …
There are mainly two types of jaw crushers: the single toggle and the double toggle (or Blake crusher). The single-toggle jaw crusher features a moving jaw suspended on the eccentric shaft. It's known for its efficiency in crushing but tends to be more susceptible to wear because of the high motion of the jaw.
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 ...
Double toggle jaw crushers are the classic style of jaw crushers. They're also popularly known as the "Blake type" because of their similar mechanism to the original jaw crusher by Eli Whitney Blake.
The Dodge Jaw Crusher is a type of crusher that is widely used in the mining industry. It was invented by Eli Whitney Blake in 1858, making it one of the oldest types of crushers still in use today. ... The crushing process begins with the rocks being fed into the crusher through a feeder mechanism. The rocks are then crushed between …

Crusher definition: Crushers are slow-speed machines employed for the coarse reduction of large quantities of solids. Jaw crushers, Gyratory crushers, and Smooth-roll crushers are the main types of crushers. They operate or are used by compression and can break large lumps of hard materials. They find applications in the rockery and mining industries.
