Jaw Crusher Components: There are several main parts of the jaw crusher: frame, jaw plate, side guard plate, and transmission part. The frame is a four-walled rigid frame, and it is used to hold the eccentric shaft and stand the reactive force of crushed material. So, the frame needs sufficient strength and rigidity. It is usually made of cast ...
applications, is a challenge where both jaw crushers and gyratory crushers have proven themselves for decades. But the downside is that their large installation height means they require extensive and costly structures and caverns. With its new eccentric roll crusher (ERC ®) thyssenkrupp Industrial Solutions has
In a double-toggle jaw crusher, the moving crusher jaw is driven by the eccentric shaft that moves the front and rear toggles up and down. Each shaft revolution causes the moving crusher jaw to close at the downstroke and open up during the upstroke. The toggle is kept in place by spring-loaded tension rod.
Wearing parts in the gyratory crusher may be either chilled cast iron or manganese steel, depending on the character of the material to be crushed and the particular class of service for which the machine is intended. Standard crushers, in the small and medium sizes, are customarily fitted with chilled-iron head and concaves for …

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.
The swing jaw is connected to the eccentric shaft by a pitman that moves back and forth by an eccentric mechanism. The toggle plates are located between the swing jaw and the fixed jaw and they are …
What is an overhead eccentric jaw crusher, and what are its advantages? An overhead eccentric jaw crusher has an eccentric shaft located above the jaw plates. This design provides a more even wear …
Jaw crusher movement is guided by pivoting one end of the swinging jaw. and an eccentric motion located at the opposite end. [4] The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws .For instance, a 22 x 30 jaw crusher has an opening of 22" by 30", a 46 x 46 jaw crusher has a opening of 46" square.
