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 also medium crushing and fine crushing. The slow speed of coarse crushing will greatly affect the subsequent production. There are many factors that affect coarse crushing. The most common one in production is the influence of feeding.
 

 

Although jaw crusher is a coarse crushing tool with powerful functions, it is not omnipotent. Some processing personnel will use the feed port size as the maximum feeding size. This operation can easily cause the raw material with a large particle size exceeding the specified size to block the crushing chamber. Once blocked, the machine must be stopped to remove the raw material. After removing it, it is necessary to carefully check whether the machine has other damage, so it is very important to strictly control the particle size of the raw material.

 

Some processing personnel are too cautious in the production process. Insufficient feeding causes the jaw crusher to "not eat enough". The consequence of insufficient feeding is that the production efficiency is seriously affected. When the problem is found, there will be an over-feeding problem, that is, excessive feeding, which causes the jaw crusher to eat too much and "indigestion", and it is unable to crush the material in time, causing greater wear and damage to the machine. Therefore, it is necessary to control the feeding rhythm, such as adjusting the angle of the feeding bin to ensure smooth feeding and no material compression, so that the rhythm of the feeder is consistent with the processing rhythm of the jaw crusher.

 

Most processing plants now use vibrating feeders, which are equipped with grate bars and have screening functions. In actual production, due to the limitations of the amplitude and feeding angle of the feeder, it is easy for materials to block the grate bars during screening, and the initial screening cannot be effectively achieved. Poor screening effect will directly affect the production of the jaw crusher. At this time, it is necessary to adjust the amplitude and angle of the feeder to give full play to the screening function of the feeder.

 

The size of the jaw crusher's discharge port determines the size of the machine's processing capacity. Only when the discharge is smooth can the feeding be smooth. As a coarse crushing equipment, the size of the discharge port of the jaw crusher should be coordinated with the feeding progress of the medium crushing equipment. According to the production needs of the downstream, the size of the jaw crusher's discharge port should be adjusted in time.

 

The above are the usage skills related to jaw crusher feeding. In addition, the rotation speed of jaw crusher and the humidity of materials are also factors affecting production efficiency. All kinds of factors should be taken into consideration in production, so as to maximize the performance of jaw crusher and obtain the greatest benefit.
