The types of jaw crusher
The principle of simple pendulum jaw crusher
Moving jaw hanging heart shaft, swinging. Eccentric shaft rotates, link to do reciprocating movement up and down, also do reciprocating motion drives the two pieces of thrust plate, pushing around moving jaw do reciprocating motion, crushing and discharging. This crusher adopts crank connecting rod mechanism, although have very big by the moving jaw broken reaction, while the eccentric shaft and connecting rod bearing is not big, so much on industrial made mainframes and medium-sized machine, used for crushing hard materials. In addition, this kind of crusher work, the trajectories of each point on the moving jaw is spindle as the center of circular arc, arc radius is equal to that point to the axis of the distance, the upper arc small, bottom arc, crushing efficiency is low, its broken than general for 3-6. Because of its simple movement, therefore calls simple swing jaw crusher.
Jane simple pendulum jaw crusher compact structure, small eccentric shaft, a bearing; Because of the moving jaw vertical displacement is small, processing material less excessive broken phenomenon, when moving jaw jaw plate wear small.
The principle of compound pendulum jaw crusher
Upper jaw hanging on the eccentric shaft directly, as a connecting rod connecting rod, the direct drive of eccentric shaft, the lower end of the moving jaw hinge connecting thrust plate support after the frame of the wall. When the eccentric shaft rotation, the trajectories of each point on the moving jaw is a circular line of suspension point (radius) is equal to the eccentricity, gradually become oval down, more to the bottom, the partial the oval, until the bottom and the thrust plate connection point trajectory for arc line. Due to this kind of mechanical motion trajectory of each point on the moving jaw is more complex, so called complex oscillating jaw crusher.
Compound pendulum jaw crusher compared with simple pendulum, its advantage is: quality is lighter, less component, the structure is more compact, crushing cavity is good, the outside material block by uniform broken, to move the lower jaw introduced mandatory finished discharging, so the productivity is higher, than with the specifications of the simple pendulum jaw crusher; 20-30% higher productivity Material block at the bottom of the moving jaw have larger rolling up and down movement, easy in cube shape discharge.
