· Double Jaw Crushers. Double toggle jaw crushers are usually used for crushing hard, abrasive rocks, glass and ferrous metals. Unlike single ones, double toggle jaw crushers are much heavier and have a lot of moving parts. Plus they don't include rotary motion. Instead they crush materials between two massive jaw plates. The crushing process happens, when the feed material .

 · Things Jaws Do: drop open, clench ... HINT: When describing any part of the body, try to use cues that show the reader more than just a physical description. Make your descriptions do double duty. Example: Hank leaned back in his chair, hands laced lightly over his torso, considering me. I couldn't look at his eyes, too scared to see his decision there, so I stared at his chin—dimpled and ...

The gyratory crusher shown in Figure employs a crushing head, in the form of a truned cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the bottom, the characteristics of the machine are ...

 · Jaw crushers are also compression crushers that allow stone into an opening at the top of the crusher, between two jaws. One jaw is stationary while the other is moveable. The gap between the jaws becomes narrower farther down into the crusher. As the moveable jaw pushes against the stone in the chamber, the stone is fractured and reduced, moving down the chamber to the opening at the .

 · A jaw crusher can handle soft to very hard materials and slightly wet material but not sticky. These machines use compression to break material. They are used in heavy mining, quarried materials and recycling. A gyratory crusher can handle soft to very hard materials and slightly wet but not sticky. These machines have a concave surface and a cone head, like the jaw crushers. These .

A jaw or toggle crusher consists of a set of vertical jaws, one jaw is kept stationary and is called a fixed jaw while the other jaw called a swing jaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a class II lever or a nutcracker. The volume or cavity between the two jaws is called the crushing chamber. The movement of the swing jaw can be quite small, since ...

 · Universal or Three Jaw Chuck. A threejaw chuck is shown in the figure. This is the most commonly used types of chuck in the lathe machine. The three jaws are generally made of highquality steel and are arrogated at an angle of 120° to each other. During the operation, the jaw teeth are made to mesh with scrawl spiral teeth (Bevel teeth). The meshing causes a moment of all three jaws either ...

Jaw crushers are used as primary crushers, or the first step in the process of reducing rock. They crush primarily by using compression. The rock is dropped between two rigid pieces of metal, one of which then moves inwards towards the rock, and the rock is crushed because it has a lower breaking point than the opposing metal piece. crusher is famous product of heavy industry. An ...
