How to improve the production capacity of jaw crusher
According to the user, sometimes some jaw crusher production capacity can not meet the design requirements, in order to meet the demand of users, a analysis of the reasons for this phenomenon, some analysis and discussion in theory, to diagnose jaw crusher, so as to optimize the structure of the jaw crusher design, improve the jaw crusher production capacity.
Working principle of the jaw crusher:
Jaw crusher work, motor rotation, through the v belt and pulley drive eccentric shaft, the fixed jaw according to adjust good path of motion, activity fixed jaw jaw slabs and periodic reciprocating swing, when the jaw near the material will be squeezed between the two jaw, splitting and bent and broken, when the jaw left, crushing cavity bottom have been broken to less than the material discharging mouth, by automatic fall, gravity is located in the upper part of the crushing cavity material, has not broken to less than the discharging mouth size, just as the discharge in a certain distance, until the moving jaw forced by fixed jaw plate again, crushing cavity materials has fallen again continue to squeeze and broken; So go on, until all into the crushing chamber material from the discharging mouth eduction.
The analysis of production capacity:
Jaw crusher production capacity refers to the crusher in working normally, how much per hour broken material, size and the size of the crushing capacity of production capacity and the size of the discharge capacity, discharge capacity and insufficient or broken broken enough and discharge capacity is insufficient, or insufficient both will affect the production capacity of crusher. By field observation test, crusher extrusion capacity has reached the design requirements, namely is said crusher crushing capacity is enough; Therefore, the production capacity is insufficient, the main is caused by insufficient discharge capacity.
Way to raise the capacity of production:
In order to improve the production capacity of jaw crusher, and narrow the scope of its use, ensure the original broken ability and meet the design performance requirements, only will be changes in the activity of the shape of the jaw, make upper ensure constant Angle between the jaw plate, and the lower Angle for 0 °. So, will the original a crushing cavity is divided into two parts of the discharge and crushing cavity, the material in the crushing chamber was broken after discharge from discharge cavity, at this point, the material is no longer in the shape of the wear surface rendering trapezoidal prism, but in a cross section of the rectangular prism shape, moving jaw every swing, discharge material.
Thus, without changing other cases, the performance of crusher activities improved the shape of the jaw is more advantageous to discharge, is conducive to the improvement of production capacity.
