Jaw crusher is the most common machine in the production of coarse crushing. Coarse crushing is the first step in the crushing process. After the coarse crushing, there are medium and fine crushing processes. The slow processing speed of the coarse crushing will greatly affect the subsequent production. There are many factors that affect coarse crushing, and the most common one in production is the influence of the feeding link.
Sufficient attention should be paid to the feed size that is too large. Although the jaw crusher is a coarse crushing tool with powerful functions, the jaw crusher is not a panacea. Some processors will use the size of the feeding port as the maximum feeding size. This operation can easily cause the raw materials with large particle sizes in the raw materials to block the crushing cavity. Once blocked, the machine must stop to take out the raw materials, and carefully after taking them out. Check the machine for other damage, so it is very important to strictly control the particle size of the raw materials.
Feeding to master the rhythm. Some processing personnel are too careful in the production process, and insufficient feeding leads to “insufficient food” for the jaw crusher. The consequence of insufficient feeding is to seriously affect the production efficiency. When the problem is found, there will be an excessive problem, that is, excessive feeding, which will cause the jaw crusher to eat too much and "indigestion", unable to break the material in time, causing greater wear and tear to the machine. Therefore, it is necessary to control the rhythm of feeding, such as adjusting the angle of the feeding bin to ensure smooth feeding and no pressing, so that the rhythm of the feeder is consistent with the processing rhythm of the jaw crusher.
Pay attention to the preliminary screening of the material. Most processing plants now use vibrating feeders, which are equipped with grate bars and have a screening function. In actual production, limited by the amplitude of the feeder, the feeding angle and other factors, the phenomenon of material jamming of the grate bars is easy to occur in the screening process, and the preliminary screening cannot be effectively achieved. The 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 give full play to the screening function of the feeder.
If there is feeding, there will be discharge, and the adjustment of the discharge port of the jaw crusher is also very important. The size of the discharge opening of the jaw crusher determines the processing capacity of the machine. As the primary crushing equipment, the size of the discharge opening should be coordinated with the feeding progress of the secondary crushing equipment. According to the downstream production needs, adjust the size of the discharge port of the jaw crusher in time.
The above are the usage skills related to the feeding of the jaw crusher. In addition, the speed of the jaw crusher and the humidity of the material are also factors that affect the production efficiency. Various factors must be considered in production, so that the efficiency of the jaw crusher can be maximized. Get the maximum benefit.
