Analysis of jaw breaker operation trajectory
In the process of crushing ore, the operation trajectory of jaw breaker determines the crushing quality and efficiency of ore.
Please see the following analysis for the specific operation trajectory of jaw breaker:
1. From the viewpoint of crushing materials, the operation trajectory of jaw breaker is required: the horizontal stroke of jaw should be large enough, and make it increase gradually from discharge port to feed port.
2. In terms of reducing the liner wear, the vertical stroke of the jaw should be small enough, and make it help the discharge.
The above two operation trajectories, under good control, can not only effectively improve the productivity of jaw breaker, but also largely reduce the wear of internal equipment liner.
The operating characteristics of the compound jaw breaker developed to meet the development of society basically meet the above requirements, and the horizontal stroke of the moving jaw is larger, while the discharge port to the feed port is gradually increasing, so it is more favorable to the crushing of ore. The direction of the running track of the jaw is also more favorable to the discharge, so it has higher productivity, but its shortcoming is that it has a large vertical stroke, and to a certain extent, the liner plate will be worn out faster, so the application cycle of the equipment will be shorter.
As you can see, the operating characteristics of the moving jaw are decisive in evaluating a jaw crusher, and if its movement characteristics are poor, the performance of the equipment will be very poor and basically cannot be used for ore crushing. Here we introduce you a simple way to test the running characteristics of the jaw, that is, to calibrate the right angle coordinates on a piece of white paper and put it on the inside of the frame wall of the jaw breaker feed opening, then press the pencil with your hand at the horizontal height of the jaw feed opening, put the pencil tip on the paper, slowly make the pulley rotate, and when it turns to one week, the real running track of the jaw will be shown on the white paper. And then use the ruler to measure the actual value, and judge the performance of jaw breaker operation track. Similarly, the discharge opening test can also be applied in this way.
