Jaw crusher is the most common machine in coarse crushing production. Coarse crushing is the first step in the crushing process. After coarse crushing, there are medium crushing and fine crushing. Coarse crushing processing speed affects the subsequent production. There are many factors affecting coarse crushing, the more common in production is the influence of the feeding link.
Sufficient attention should be paid to the excessive size of the feed. Some operators will use the feed opening size as the maximum feed size, this operation is easy to make the large raw materials that excess the specification particle size of raw materials stuck in the crushing chamber. Once the material is blocked in jaw crusher, the machine should stop and take out the raw material. After taking out, the machine should be carefully checked for other damage, so it is very important to strictly control the feeding particle size of raw material.
Feed speed. Some operators are too careful in the production process, insufficient feeding leads to jaw crusher “not enough to eat”. The consequences of insufficient feed will seriously affect the production efficiency. Another situation is excessive feeding, resulting in jaw crusher unable to break the material in time, causing greater wear and tear damage to the machine. Therefore, it is necessary to control the feed speed, such as adjusting the Angle of the bin, to ensure smooth feeding, no pressing, and make the feeding speed of vibrating feeder matching with the jaw crusher working speed.
Pay attention to initial screening of materials. Now most processing plants are using vibrating feeder, this feeder with grate, has screening function. In the actual production, the amplitude of the feeder, feeding Angle and other factors are limited, in the screening of material is easy to jam the grate, cannot effectively achieve the initial screening. Poor screening effect will directly affect the production of jaw crusher. At this time, it is necessary to adjust the amplitude and Angle of the feeder to make full use of the screening function of vibrating feeder.
The above is the use of jaw crusher feeding skills, in addition to the speed of jaw crusher, material humidity and other factors are also affect the working efficiency of jaw crusher. In the production, all kinds of factors should be taken into account, so as to maximize the effectiveness of jaw crusher, get the greatest benefit.
