Introduction The cavity of the jaw crusherconsist of moveable jaw and fixed jaw, which imitate the movement of the animal’s two jaws to complete the materials’ crushing . And now jaw crusher has found its extensive application for the mid crushing of the various ores and large-size materials block in the field of mining, smelting, building material, highway, railway, water conservancy and chemical industry, etc. PDF Download ! Jaw Crusher Working Principle This working manner of jaw crusheris 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. Compared with the single toggle jaw crusher,the oscilation jaw crusher features light weight ,simple components ,compact structure ,and finely plump crushing quality production,.And also the materials can suffered evenly crushing and the final products can be forcedly discharged out by the lower end of the moveable jaw ,which have improved the high production efficiency by 20-30% . Jaw Crusher Working Feature The jaw crusher can be used as the coarse and mid cruhsing in the field of mining, building materials and construction, etc. According to the width of the feeding hopper ,the jaw crusher can be divided into three kinds :large ,mid and small .And the large size is the machine with the feeding width of over 600mm and the mid size is at the range of 300-600mm,and the small size is less than 300mm. The working parts of the jaw crusher are two pieces of jaw plate and one is the fixed plate (fixed jaw), which is vertically fixed on the front side wall. While the other is the flexible plate( moveable jaw),which is positioned slopely and form a crushing cavity (working cavity) with the fixed jawplate. And the moveable jawplate will periodicly close or leave the fixed jaw plate .When they leave each other,the materials will enter the crushing cavity and the final products will be discharged from the bottom of the machine. And when they close with each other,the materials between the two jaw plate will be crushed by the extrusion ,bending and crack. Jaw Crusher Advantages 1.Deep crushing cavity and no dead time control have improved the feeding capability and the production output . 2.Large crushing ratio and even particle size. 3.Gasket discharge opening adjustment equipment makes the function more reliable and convenient , adjustment more large ,and the equipment more flexible . 4.The lubrication system more secure and reliable ,the spare parts can be more changed ,and low maintenance working. 5.Simple structure and relable function,low operation cost. 6.Energy-saving : the single machine can make the energy-saving about 15%~30% and the system energy-saving over one time. 7.Large range of the discharge opening range can satisfy the various requirements of the customers . 8.Low noise and dust pollution.
