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 devised for rock and ore breaking.

How do jaw crushers work? Jaw crushers use compressive force to break down large materials into smaller, more manageable pieces. It has two crushing jaws (one is stationary while the other one is moving) that produces mechanical pressure for crushing the materials. The two vertical crushing jaws create a V-shaped opening called the crushing ...

Jaw Crushers; Cone Crushers; Typically, the initial crushing stage is completed using either gyratory crushers or jaw crushers. It is often the case that there will be only one crusher installed, and this will be referred to as the primary crusher. Cone crushers are more often used for 2nd, 3rd & 4th stage crushing steps (although not always).

The models for determining the power required for operating jaw crushers have mostly been derived using Bond's work index. While these gave satisfactory estimations of power, it must be remembered that Bond's expression was derived using a tumbling mill where the forces of comminution are not quite the same as that in jaw crushers.
