To improve the production quality of briquette machine and produce briquettes of high quality, we need to control the moisture content of the raw material. Raw material of large humidity would make the structure of briquette produced not that compact and the quality is poor. To this end, we usually control the moisture content of the raw material between 5% and 12%. If the moisture content is less than 5%, the intensity property of the material would get poor that the efficiency of production would be lower. While if the moisture content of the raw material is above 12%, the briquettes produced would be flexible and the density is small. In this case, the drying machine plays an important role in adjusting the moisture content of the raw material. Put the raw material in the dryer for drying 1 or 2 times to meet the requirement of briquette machine. Then, the briquettes have good quality and stability, which can meet the requirements of raw material moisture standard for production.

As is known to all, the carbonizing furnace of briquette machine equipment can complete the production process of carbonization. The molding rate of carbonization not only related to the molding technology, but also have close relationship with the selection of raw materials. The carbonization speed of larger raw material is slow, because the heat transfer to the inner layer of raw material is a slow process. Sawdust can also be used as the raw material of carbonization and the carbonization process is faster, but the market value of the powder charcoal it produces is low. If the material with large particle size and density is used in the carbonization process, it may be broken during carbonization and the charcoal produced is fragile compared to other charcoal. The study found that the best raw material used in the mechanism charcoal production is 25-70 mm in diameter. The requirement can improve the efficiency of carbonizing production, at the same time, it can also provide good processing raw materials for iron smelting industry.
