The eccentric throw is one of the most important parameters in defining the job that your cone crusher does. The mantle in a cone crusher spins in conical pendulum motion. That means it doesnrsquo;t stay in the center of the chamber ndash; it sweeps around moving closer and further away from the concave. This is what creates the crushing action. At a given point on the concave material is ...
In a typical jaw crusher two outer bearings located on either side of the main frame support an eccentric shaft while two inner bearings support a movable jaw. These are commonly known as “Pitman” bearings. The reciprocating motion of the shaft moves the Pitman against a second stationary jaw. As material reaches the bottom of the ...
Mar 28 2019 Double-toggle jaw crushers. 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.

Be composed of mobile jaw eccentric shaft and belt pulley etc. to drive the machine. We all know that jaw plate is the most easily worn parts among various of parts installed in jaw crusher. Therefore in order to use the machine efficiently the jaw plate should be checked and replaced regularly.
/ JAW CRUSHER TYPES. There are two main groups of jaw crushers categorized according to their jaw movement mechanism. - Single-toggle jaw crushers - Double-toggle jaw crushers. In single-toggle jaw crushers the movable jaw is supported by the bearing on an eccentric shaft driven by the pitman to which it is attached.
the moving jaw and based on this defines the formula to define the optimal number of revolutions the eccentric shaft. Under the optimum number of revolution the eccentric shaft the number of revolutions is assumed to ensure that the crusher achieves the maximum crushing capacity. Keywords: jaw crusher capacity optimum speed shaft
Motor power is applied to the crusher drive shaft which in turn transfers rotation to the eccentric shaft. Rotation of the shaft causes two types of motion in the moving jaw. The first is a cyclic pivoting open-and-close motion caused by the top of the moving jaw leveraging against a toggle plate at the bottom of the moving jaw.
RockSledger jaw crushers feature massive stress relieved single plate walls with deep and substantial external side stiffeners and a high quality forged steel eccentric shaft. The shaft is fully machined and has a ground finish on all bearing contact surfaces to increase resistance to shock loadings resulting in longer machine life.
Such known crushers (e. g. manufactured by Kennedy Van Saun Telsmith Iowa Manufacturing Co. and others) consist of a stationary jaw and a swing jaw mounted directly on the eccentric shaft so that it receives downward and forward motions. The lower end of the swing jaw is held in position against the toggle by a tension rod.
ABOUT Single Toggle JAW CRUSHER Heavy duty with robust design single toggle Jaw Crusher is having Mild steel fabricated body. Body is strengthened to withstand heavy load. Main (Eccentric) shaft is running on antifriction bearings. Jaw plates and chick plates are made from highly wear resistance manganese steel.
Jaw crusher structure.
