Jaw crusher are mainly used to proceed the medium particles crushing of various ores and large size materials with the crushing pressure of less than 320Mpa.
jaw crusher for sale.And Jaw crusher can be divided into two kinds : coarse and fine crushing.And this series of jaw crusher have full specifications of the products and the feeding size is 125mm750mm ,which have become the primary crushing equipment. And Jaw Crusher is widely used in mining, metallurgy, construction, highway, railroad, conservancy and chemistry industries,etc. This series of Jaw Crusher feature large reduction ratio, even granularity, simple structure, reliable operation, convenient maintenance, and low cost,etc.
The main structure of jaw crusher are including frame,eccentric shaft,large pulley,fly wheel ,moveable jawstock,side guard ,toggle plate,backseat of the toggle plate ,fixed or movaable jaw plate and so on.And the toggle plate have taken the secure effects.This working manner of jaw crusher is hyperbolic extrusion. And its working principle is as follows.Through the motor's wheels, the eccentric shaft is driven by the belt and the belt wheel to make the jawstock move by a regulated track. The angle between the toggie plate and jawstock will become large as the up of the jawstock. This will push the moveable jaw plate towards the fixed jaw plate,which can realize the multi-crushing of the materials.The angle between the toggie plate and jawstock will become small as the down of the jawstock. The moveable jaw plate will leave the jaw plate at the presure of the tension rod and spring ,meanwhile ,the final products will be discharged from the dischargeing opening.Along with the continous rotating ,the crusher will comlete the periodic crusing and discharging movement ,which can realize the batch process.
A jaw or toggle crusher consists of a set of vertical jaws, one jaw being fixed and the other being moved back and forth relative to it by a cam or pitman mechanism. The jaws are farther apart at the top than at the bottom, forming a tapered chute so that the material is crushed progressively smaller and smaller as it travels downward until it is small enough to escape from the bottom opening.
stone crusher for sale. The movement of the jaw can be quite small, since complete crushing is not performed in one stroke. The inertia required to crush the material is provided by a weighted flywheel that moves a shaft creating an eccentric motion that causes the closing of the gap.
Single and double toggle jaw crushers are constructed of heavy duty fabricated plate frames with reinforcing ribs throughout. The crushers components are of high strength design to accept high power draw. Manganese steel is used for both fixed and movable jaw faces. Heavy flywheels allow crushing peaks on tough materials. Double Toggle jaw crushers may feature hydraulic toggle adjusting mechanisms.
Jaw crusher working principle
Upper jaw hanging in the eccentric shaft directly, as the crank connecting rod, eccentric directly by the eccentric drive shaft, the bottom hinge of the jaw thrust plate support attached to the rear wall of the rack. When the eccentric shaft rotates, the moving jaw at various points along the trajectory is a line from the suspension point of the circle (radius equal to the eccentricity), and gradually down into an oval, the more down to the Ministry, the more oval-shaped side, until the lower thrust plate with connection point for the arc line trajectory. Because of this machinery moving jaw at various points along the trajectory is more complex, it is called complex swing jaw crusher. Reciprocate jaw crusher compared with the simple pendulum, and its advantages are: quality of light, fewer components, more compact, better degree of crushing cavity filled, the material blocks are evenly broken equipment, to move the lower jaw mandatory introduction of product discharge, and therefore higher productivity, compared with the specifications of the simple pendulum jaw crusher productivity 20-30%; material block in the lower jaw moving up and down rolling movement with large,
Crushing Palnt For Sale. easy to cubic shape unloading, reducing the swing as simple as a sheet product ingredients, product quality is better.
