Jaw Crusher is a kind of stone crusher, and jaw crusher is also called rock crusher. Jaw crusher is widely used in many departments including Mining, Smelt metal, Building materials, Public road , Railway, Water conservation, Chemical industry and so on . Using the traditional design methods, it is difficult to design economical jaw crusher to meet the requirements of strength. In the current environment of economic crisis, it is significant for crusher enterprises to structural analysis and optimization of weight loss based on finite element theory to meet the strength and stiffness in order to survival and development, and to shorten the gap and catch up with the world advanced level.
In this paper, combining with the structural characteristics of PE -600×900 jaw crusher, the distributing situation of strength and stiffness about framework, mobile jaw body, flywheel and pulley of jaw crusher are discussed when jaw crusher works on the maximum breaking force state. Parts of affluence and lack about strength and stiffness are found, and optimization of weight loss is carried on to ensure the performance of the original machine did not fall by finite element theory and parametric modeling method.
In order to cope with the crushing market demand, the company launched special coarse jaw broken medium-grained materials processed further processing to meet the production requirements of the particle size fineness, crushers, screening equipments and stone production line equipment configuration is the main basis to determine customers on the use of stone specifications, as well as production and stone, gravel production line equipment more product details. hammer crusher:http://www.hx-china.com/2.html
The main structure of the Jaw Crusher are composed of stander, eccentric shaft, belt pulley, flywheel, movable jaw plate, wrist plate ,adjustable gap screw, offsetting spring, fixed jaw plate. The wrist plate also has the effect of guarding.
This Jaw Crusher’s crushing style is the type of driving extrusion. The motor drives the belt and belt pulley to make the moveable jaw move through the eccentric shaft. When movable jaw is rising, the included angle between the wrist plate and movable jaw become bigger to drive the movable plate to be close to the movable plate. At the same time the material is squeezed and rubbed, rolled to achieve multiple crushing;
When movable jaw is descending, the included angle between the wrist plate and movable jaw becomes smaller. Now the crushed material is discharged from the crushing cavity, with the continuous rotation of the motor, the movable jaw crushing and discharging the material periodically to realize batch production.
Finally, According to the results of strength and stiffness about the various components of jaw crusher, optimal parameters are set. Then, optimal results of them are found to ensure the performance of the original machine did not fall by optimization module of ANSYS. So it can provide reference for enterprises to reduce costs and enhance competitiveness.
