Jaw crusher is an important equipment on many mine production lines, There are 4 bearings on the eccentric shaft for jaw crushser: 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 lubried with an oil bath system. Bearings that support the main shaft. Normally ...
In a typical jaw crusher, two outer bearings loed 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 reciproing motion of the shaft moves the Pitman against a second, stationary jaw. As material reaches the bottom of the ...
When the small jaw crusher working, belt and belt pulley are driven by a motor. The movable jaw moves up and down via eccentric shaft. The angle between fixed jaw and movable jaw becomes smaller when the moving jaw runs down, then the materials are crushed into pieces. It becomes bigger when the movable jaw runs up.
· Generally speaking, jaw crusher spare parts are jaw plate, toggle plate, bearing and eccentric shaft. Eccentric shaft function. Jaw crusher eccentric shaft plays an quite important role in jaw crusher operating. The pitman is put in motion by the oscillation of an eccentric lobe on a shaft that goes through the pitman's entire length.
Eccentric shaft This is made of hardened steel (high carbon steel). It put the moveable jaw stock in motion as a result of the eccentric lobe on the shaft as shown in Figure 2 It is this motion that produces the needed force to crush materials. Figure 2: Eccentric shaft. Moveable jaw (manganese die) Figure 3: Moveable jaw.
· 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, the eccentric shaft of jaw crusher is easy to be broken.
Jaw crushers single toggle crusher double toggle crushers process medium to hard quarry rock or other materials by pressing it between the fixed jaw and the swing jaw the swing jaw being the moving part is attached to a rotating eccentric shaft the fixed jaw is an integral part of the crusher frame both jaws are fitted with manganese jaw liners that can be replaced or reversed.
When the small jaw crusher working, belt and belt pulley are driven by a motor. The movable jaw moves up and down via eccentric shaft. The angle between fixed jaw and movable jaw becomes smaller when the moving jaw runs down, then the materials are crushed into pieces. It becomes bigger when the movable jaw runs up. The movable jaw plate leaves the fixed jaw plate under the action of tension ...
Jaw Crusher >> EMail:joyal >> Http:// Work principle The motor drives the mobile jaw up and down through eccentric shaft. The angle between toggle plate and mobile jaw increases when mobile jaw plate moves up. So the mobile jaw plate closes up the fixed jaw plate. The stuff will be crushed in this process. The angle between toggle plate and moving jaw ...
· The present overhead eccentric jaw crusher (Fig, 1) contains a frame 1 to which a stationary jaw 2 is fixed, and a swing jaw 3. The latter is mounted on bearings 4 of its hinge 5 on a multieccentric shaft 6 that is installed in bearing supports 7 (Fig. 4) of the frame 1 and provided with a mechanical drive 8.
Jaw crusher is posed of frame rotating jaw eccentric shaft jaw plate and plate knee etc The motor drives the eccentric shaft through Vbelt making the movable jaw do periodic movement according to the well timed track The material is crushed in this process The frame adopts whole cast steel structure or welding steel plate . JoyalJaw CrusherJaw Crusher For SaleJaw Crusher. The strip and strip ...
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 moving jaw has a pure reciproing motion toward the fixed jaw. The crushing force is doubled compared to single toggle crushers and it can crush very hard ores. The jaw crusher is reliable and robust and therefore quite popular in primary crushing plants ...

The coarse particles are transferred into the crushing chamber.
Jaw crushers are widely used in mining smelting, building materials, roads, railways, water conservancy, and chemical industries. There will be a strong vibration in the work, because of the large hardness of crusher materials. Therefore, the work of the installation of a jaw crusher is very important.
