Jaw crusher

The principle of operation and features of jaw crusher

The crushing chamber having a wedge shape and formed by two cheeks, one of which in most cases is fixed and the other movable, served the material to be crushed. The wedge-shaped design of the crushing chamber, the material pieces is located at the height of the camera according to their size: the larger at the top, less at the bottom. Movable cheekperiodically approaching stationary, while the convergence of the cheeks (the compression stroke) pieces of crushed material, during the withdrawal of the movable cheek (idling) pieces of material moving down down under the influence of gravity, leaving the crushing chamber, if their size became smaller than the narrowest part of the cell called the exit slit, or take up a new position corresponding to its new size. Then the cycle repeats. Dimensions of loading and discharge openings are a Central feature of jaw crusher, so the width of the aperture determines the size of a piece of material loaded.

Breaker plate, the surface of which is formed with a longitudinal corrugation, are the main parts of jaw crushers. During operation, when approaching the movable cheek to still, the protrusion comes into the cavity, which ensures the destruction of the stone under the action of bending, what rocks have resisted weakly. Jaw crusher with a complex movement significantly different from crusher with a simple movement of the cheeks. Performance crusher with a complex movement of the plate above, since the crushing of materials occurs over 4/5 of turnover of the eccentric shaft. For crushing strength of rocks used crusher with two movable jaws.

To ensure the normal operation of jaw crushers is only possible if the material being crushed is forced up there by clicking on the crusher, and this in turn depends on the capture of the angle between the crushing plates.

The key to a great work of jaw crushers is a high technical literacy of staff and compliance with the rules of technical operation at your shop. The launch of jaw crushers has been consistent. 2-3 minutes is necessary that this crushing equipment has idle capacity, then you need to install a normal rate of rotation of the eccentric. It is also important to ensure the constancy of the particle size of the downloadable pieces of crushed material, the magnitude of which, as mentioned above, should match the width of the feed opening – throat crusher – and angle capture.
