Jaw crusher is used as primary crusher, it's reduction ratio is usually 6:1. It uses compressive force to break the material, this mechanical pressure is achieved by the two jaws of the crusher. It is called a jaw crusher because it works the same was a human jaw does-food goes into your mouth and your bottom jaw pushes the food up against ...

The reduction ratio is a critical parameter for the performance of a jaw crusher. It affects the capacity, quality, and energy consumption of the machine. A high reduction ratio means a smaller product size and more fines. It also implies higher crushing force and energy consumption. On the other hand, a low reduction ratio means a larger ...

Crusher Blockage. Clearing blocked jaw crushers can be very hazardous and many plant operators have been killed carrying out this task. Blockage incidents can be greatly reduced by supplying rock that is properly sized to match the primary jaw opening. Prevention of oversize in feed material starts at the face with good fragmentation.

Best suited for secondary crushing applications, cone crushers are designed to crush pre-sized materials, usually 100mm, 150mm or 200mm, depending on the size of the crusher. Cone crushers can form finished products down to 12mm or less. Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are ...

Jaw crushers typically use the principles of compression and friction to break materials down. They're extremely powerful equipment that should be used with the utmost care. Jaw crushers are so powerful that they've earned the moniker "rock breakers" because of their brute force. All jaw crushers will have one fixed jaw and a moving one.

Crushing Equipment / March 11, 2023 / 5 minutes of reading. An impact crusher is a machine used to crush materials by impact energy. It works by feeding the material into a rotating rotor, which is equipped with a series of hammers. As the rotor spins, the hammers strike the material, causing it to break into smaller pieces.

A fixed jaw, mounted in a V-shaped alignment, is the stationary breaking surface, while a movable, "swing" jaw exerts force on the feed material by pushing it against the stationary plate. The space at the bottom of the "V"-aligned jaw plates is the output gap that dictates the size of the crushed product from the jaw crusher.
