What is a Jaw Crusher? Telsmith

A jaw crusher is a compression type crusher, comprised of a fixed jaw and moving jaw positioned in a (V). The movable jaw compresses material against the fixed jaw, crushing the material to the desired size. The material exits the jaw through the bottom of the crusher otherwise, known as the discharge opening. Changing the discharge opening controls the product size made by the crusher.

how a jaw crusher works and what it is used for

A Jaw Crusher reduces large size rocks or ore by placing the rock into compression. A fixed jaw, mounted in a "V" alignment is the stationary breaking surface, while the movable jaw exerts force on the rock by forcing it against the stationary plate. The space at the bottom of the "V" aligned jaw plates is the crusher product size gap, or the size of the crushed product from the jaw crusher

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. The lifecycle of double-toggle jaw crushers is longer since they do

Jaw Crusher an overview ScienceDirect Topics

Jaw crusher: The material is crushed between a fixed jaw and a mobile jaw. The feed is subjected to repeated pressure as it passes downwards and is progressively reduced in size until it is small enough to pass out of the crushing chamber. This crusher produces less fines but the aggregates have a more elongated form. • Percussion crusher: The aggregates are produced by impact and hence

What Is a Jaw Crusher? Here's How It Works Cutting

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. These two form a V-shaped chamber, where the

A jaw crusher is a compression machine. It consists of 2 corrugated jaw plates (dies), one fixed (stationary) and one that is movable. The opening is wider at the top than the bottom. Shot rock type material up to 90% of the jaw opening size is typically acceptable. With material like gravel, 80% size is encouraged. As material moves from the top of the chute to the bottom, it is crushed

Jaw Crusher Components & Parts

Although the jaws do the work, the real heart of the jaw crusher and its components are the toggle plates, the pitman, and the ply wheel. These are the parts and components that generate the crushing action and provide the energy needed to break the ore. Let’s follow the chain of events within a crushing cycle to see how they all go together. The first component of the crusher is the drive

Jaw crushers are installed underground in mines as well as on the surface. When used underground, jaw crushers are commonly used in open circuit. This is followed by further size reduction in crushers located on the surface. When the run of mine product is conveyed directly from the mine to the crusher, the feed to the primary crusher passes under a magnet to remove tramp steel collected
