Qualified moisture content of raw material is the precondition for the production of high quality sawdust briquette. If the raw material is too dry, it will lead to the longitudinal crack in the sawdust briquette produced by the sawdust briquette machine for sale, even make the sawdust briquette on fire. At this moment, raw material without drying need to mixed evenly with the material used in sawdust briquette machine for sale. While if the moisture content of raw material is too high, transverse crack would appear on the surface of sawdust briquette, at the same time, air returning of the hopper and blasting of sawdust briquette machine for sale would also appear. In that case, the raw material need to be dried again. However, experienced manufacturers will try to avoid repeated drying, besides considering the cost, more importantly, the safety factor is considered. Compared with the molding and carbonizing, drying is a process with less technical content. However, there is a lot of potential safety hazard in the drying process so that users need to improve the safety awareness in the actual production of sawdust briquette machine for sale.

After repeated improvement of the scientific research department of our company, the fuel consumption of the new type high efficiency drying system is 50% of the general drying machine. The drying effect is particularly good, the raw material with the moisture content of 60% can be dried in one time. Different drying equipment should be used according to the raw materials used in sawdust briquette machine for sale. Generally speaking, there are large drying equipment, airflow dryer and drum dryer to meet different production demand of the customer, which greatly improves the production time of sawdust briquette machine for sale, lowers the production cost and make our customers in a leading position in charcoal briquette market competition. All kinds of raw materials used in the production of sawdust briquette machine for sale can be processed with our new type drying equipment for drying. The drying effect of these raw material is very ideal after repeated test of our company.

Biomass briquettes taking crop stalks (corn stalk, bean stalk, sorghum stalk, cotton stalk, rape stalk, peanut seedling, sunflower stalk), chaff, grasses, shrubs, bamboo and wood cutter head, bamboo shavings, bagasse as raw materials and produced by sawdust briquette machine for sale are featured with large density, small volume and good combustibility. They can be used as the substitute product of firewood and coal. Generally, the outer diameter of briquette is 50 to 60 mm and the aperture is 15 to 20 mm with the shape of hollow quadrangular or hexagonal prism. Also they can be made into spherical, granular and honeycomb briquette. especially suitable for heating in the northern region, greenhouses heating or the living fuel.
