eccentric shaft jaw crusher line Jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even. It is widely applied to crush high hardness, mid hardness and soft rocks and ores such as slag, construction materials, marble, etc. The pressure resistance strength is under 200Mpa, that is, suitable for primary crush.
The jaw crusher crushes materials through the periodic movement of the movable jaw. The crushing method is driven and squeezed. The belt and pulley are driven by the motor, and the movable jaw does a fixed up and down reciprocating movement through the action of the eccentric shaft. When the movable jaw rises, the angle between the toggle plate ...
17-12-2020· Jaw crushers can be divided into two basic types, single and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation, along with the toggle plate, causes a compressive action. A double toggle crusher has two shafts and two toggle plates.

01-06-2019· On installation: installation of components of jaw crusher. Next, we will learn about the installation of jaw crusher from the parts of the frame, eccentric shaft and bearings, rod bolts, brackets, movable jaw plate, and dental plates. 1.The installation of the frame. The jaw crusher is installed on the concrete foundation.
The first shaft is a pivoting shaft on the top of the crusher, while the other is an eccentric shaft that drives both toggle plates. The chewing movement, which causes compression at both material intake and discharge, gives the single toggle jaw better capacity, compared to a double toggle jaw of similar size.
11-03-2021· Eccentric shaft (pitman bearing): It is behind the moveable jaw plate, and together with flywheel with toggle plate to create a motion. So, the most important thing you must do is keeping a regular lubrication to eccentric shaft, or you will spend more than four hours in changing a new one when it is broken.
Jaw Crusher Eccentric Shaft is installed on the top of the jaw crusher. It runs through the movable jaw, pulley and flywheel. All of them are connect with each other by the eccentric shaft. The rotation of eccentric shaft causes a compressive action of the moving jaw.
20-08-2012· A multi-eccentric shaft carries the pitman. The eccentrics are spaced equally apart from each other on the shaft circumference. The device crushes the material continuously since the separate jaw sections work in turn, the more sections the more uniformly the crusher works. The different jaw sections squeeze and release the material simultaneously.

As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including, Maintenance and lubrication of eccentric shaft for pe series jaw crusher, quarry, aggregate, and different kinds of minerals.
Eccentric shaft, the main drive part plays an important role in the operation process. However, during daily production process, due to the overload operation of jaw crusher, the hardness of crushed material and the quality of toggle plate is not up to the standard, …
14-06-2021· 7. Jaw Crusher Bearings. There are typically four bearings on the eccentric shaft: two on each side of the jaw frame supporting the shaft and two at each end of the pitman. These bearings are typically roller in style and usually have labyrinth seals and some are lubricated with an oil bath system.
Figure 8.1 shows two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is installed on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action of the moving jaw. A double toggle crusher has, basically, two shafts and two toggle plates.
Eccentric Shaft Jaw Crusher Replacement. 3 mobile jaw crusher drive parts eccentric shaft is the main shaft of the crusher subjected to huge bending torque made of high carbon steel eccentric part must be finished heat treatment bearing lining tile with babbitt alloy pouring the eccentric shaft is equipped with a belt wheel at one end and a flywheel at the other 4.
06-05-2021· A sectional view of the single-toggle type of jaw crusher is shown below. In one respect, the working principle and application of this machine are similar to all types of rock crushers, the movable jaw has its maximum movement at the top of the crushing chamber, and minimum movement at the discharge point.The motion is, however, a more complex one than the Dodge motion, being the …
Eccentric movement of the jaw stock against the material crushes it slightly so that it can move down the crushing chamber. When the material reaches almost the one third of the total height of the machine, it will experience maximum crushing force and get crushed into fragments.
The working principle of jaw crushers: When working, the motor drives the belt and pulley to move the movable jaw up and down through the eccentric shaft. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, thereby pushing the movable jaw plate closer to the fixed jaw plate, and the material passes ...
20-08-2012· The twin-jaw crusher (Fig. 2) has the second swing jaw instead of the stationary one and is mirror aligned to and synchronized with the first jaw. In the pitman-type crusher (Fig. 3), the movable jaw 3 is swung on an axle 16, whereas the eccentric shaft 6 carries pitman arms 17 …
20-07-2021· In the single toggle jaw crushers, the swing jaw is suspended on the eccentric shaft which leads to a much more compact design. The swing jaw, suspended on the eccentric, undergoes two types of motionswing m otion towards the fixed jaw due to the action of toggle plate and vertical movement due the rotation of the eccentric.
