The moisture content of the raw material is one of the key factors that would influence the quality of briquettes produced by briquette machine. If the moisture content of raw materials is low, hydrolysis and heat transfer through the material will be lower, thus higher pressure should be applied in the production. If the moisture of raw material is higher, the bonding ability of raw material is poor and the briquettes produced are easy to be disintegrated. Generally speaking, the drying equipment is indispensable in the production of biomass briquette. Some details need to be noticed during raw material drying process. We hereby would like to give you some tips on how to improve the drying efficiency.
1. Feeding volume of raw material is related to the feeding speed in some extent. The more raw material is put into dryer, the lower the drying level will be. Different drying system should be used according to the requirements for production yield from clients. If the designed yield of briquette machine customers use is 2 tons per hour, however, he want achieve the production of 3 tons per hour. Then, he may speed up the feeding of raw material to rush to produce briquettes forcibly which will not only result in poor drying effect, but also further affecting the quality of briquettes or even leading to no briquettes produced.
2.Material size is another crucial factor that would impact the drying efficiency. The larger material size is, the higher the possibility of material sediment within drying pipeline will be increased. Otherwise, the passageway for material going through pipeline will be narrowed in this regard within drying channel. The drying system is also related to briquetting requirement. That means neither oversized material can achieve smooth briquetting performance nor material of too small size can be made into briquettes due to lower cohesiveness of too mealy size. That’s why a crusher is usually brought into pretreatment section in the briquette machine.
3. Hot air temperature control is interacted with feeding volume and material size as well. When the feeding volume of briquette machine to some extent within unit time is stable, the higher temperature goes, the more raw material can be put in.
The three factors mentioned above are interconnected and mutually influenced. They are bound to be inspected and controlled accordingly. This is also the reason why the operator of the briquette machine should cooperate with one another rather than working so independently.
