The loose briquettes produced by briquette machine may be caused by many reasons. The following are some common reasons and corresponding solutions:

First of all, the humidity of raw materials may be an important factor leading to loose briquettes. If the humidity of raw materials is too high or too low, it will affect the forming effect of briquettes. If the humidity is too high, the briquettes can’t be tightly compacted, and they are easy to loosen. However, if the humidity is too low, it may lead to the lack of sufficient adhesion between raw materials and the finished briquettes will not be compact enough. The solution to this problem is to strictly control the humidity of raw materials, and it is usually recommended to control the humidity between 10% and 15%.

Secondly, the pressure setting of briquette machine may not be reasonable enough. The briquette machine needs to provide enough pressure during operation to ensure that the raw materials can be tightly compacted. If the pressure is insufficient, the compact will naturally loosen. At this time, it is necessary to check whether the pressure regulating device of the equipment operates normally, and adjust the pressure parameters appropriately according to the characteristics of raw materials.

Besides, the wear of the die or design problems may also be the cause of loose compact. Die wear will affect the forming effect of briquette machine, making briquettes unable to achieve ideal compactness. If the mold has been used for a long time, it is recommended to replace it with a new mold in time. In addition, unreasonable mold design may also lead to poor briquetting effect, which requires communication with equipment manufacturers to optimize mold design.

Another possible factor is the characteristics of the raw materials themselves. If the raw material particles are too large or the fibers are too long, it will affect the compactness of the briquettes. The solution is to pretreat the raw materials, such as crushing or cutting, to make them reach the particle size and shape suitable for briquette machine.

Finally, improper operation may also lead to problems. For example, too fast or too slow feeding speed will affect the quality of briquettes. Operators need to adjust the feeding speed reasonably according to the requirements in the equipment manual, and ensure the equipment runs smoothly.

In a word, the problem of loose briquettes is usually the result of many factors. It is suggested that users conduct investigation from raw materials, equipment, operation and other aspects, and take corresponding solutions according to specific conditions. If the problem still cannot be solved, you can contact the equipment manufacturer for professional technical support. Through scientific management and maintenance of equipment, the quality of briquettes can be effectively improved and the smooth production can be ensured.
