Jaw crusher is composed 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 247 online.
Jaw crusher is one of the important crushing equipment in mining industry. It has the incomparable advantage of stable and reliable operation, easy maintenance, long service life, less dust and noise. Eccentric shaft, the main drive part plays an important role in the operation process.
· · 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. This force is also put on the shaft itself so they are constructed with large dimensions and of hardened steel.
As we know, jaw crusher is a kind of mining equipment. The equipment stands wear and tear, however it's not all. Eccentric shaft is one of the main vulnerable parts of jaw crusher. If jaw crusher fails to work caused by abrasive eccentric shaft, users would have no idea because they learn little about the maintenance and repairment of jaw crusher.
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 .
An Eccentric Turning Fixture for the 3Jaw. I loved this idea presented by Wareagle on the HMEM board. It involves making a fixture to fit the 3jaw chuck that holds the workpiece offcenter. The piccys are pretty selfexplanatory: Such a fixture would be very easy to make with a mill and lathe.
· 5. Eccentric Shaft. The pitman is put in motion by the oscillation of an eccentricity on a shaft that goes through the pitman's entire length. This force is also put on the shaft itself so they are constructed with large dimensions and with hardened steel. The main shaft that rotates has a large flywheel mounted on each end.
Eccentric Shaft an overview ScienceDirect Topics. 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 Shaft rotation causes along with the toggle plate a compressive action of the moving jaw
· Eccentricandrod mechanism, arrangement of mechanical parts used to obtain a reciproing straightline motion from a rotating shaft; it serves the same purpose as a slidercrank mechanism and is particularly useful when the required stroke of the reciproing motion is small in comparison with the dimensions of the driving shaft. In the figure, the eccentric disk .
Moveable jaw is then moved by an eccentric shaft towards the fixed jaw. The rock particles are then nipped between the jaws and crushed at a tight angle by impact of the blow and eventually discharged. d. How could the reduction ratio of the jaw crusher be .
Both the movable jaw plate and stationary jaw plate can be mounted upside down when their lower ends are severely worn. The eccentric shaft is driven by a fly wheel via belts. As the motor drives the eccentric shaft via the Vbelt, the movable jaw moves along a predetermined route to compress the material.
eccentric shaft life is dependent on load acting on the eccentric shaft, its geometry, metallurgical properties and wear. Today in design and development of eccentric shaft by using the good quality of raw material that is alloy steel with composition of Fe (%), Al (%), C (%), and Mo (%) by
Jaw crusher eccentric shaft material Products. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any sizereduction requirements including, Jaw crusher eccentric shaft material, quarry, aggregate, and different kinds of minerals.
270° eccentric shaft peg rotation Rotating the eccentric shaft through a third quadrant (180–270°) moves the planetary gears and the eccentric shaft peg to the 270°position, causing the planetary peg to orbit even more to the right hand side (Fig. (d)). Consequently further opposite direction steer will be provided.
· – Moveable parts: jaw plate, eccentric shaft, bear, belt pulley and other components. The working principle of the jaw crushers is very simple. Powered by a diesel or gas motor, the jaw crusher brakes materials in a crushing chamber.
