How to control the cost of raw materials in the production of briquette machine?

The main raw materials for making charcoal with briquette machine are sawdust and waste materials of wood. If local wood is abundant, the price of raw materials can be controlled within 150 yuan per ton. You can also purchase the biomass briquettes raw materials from the surrounding areas. If the raw materials are too far, it will increase the cost of transportation. The wood tar produced during the carbonization process in the carbonizing furnace can be recovered.



In addition, the carbonization time should be mastered when using the carbonizing furnace to avoid excessive carbonization resulting in excessive ash content. In the carbonizing process of logs, due to the different thickness of logs, the finer branches will be carbonized and overburned to ash, and the thicker branches can not be carbonized fully. Therefore, the branches with the same thickness should be put into a stove when carbonizing. (Get to know how to make rice husk briquettes)

Briquette machine is often used in the production of mechanism charcoal. According to different raw materials, the carbon content, combustion value and calorific value of the finished product would also be different. The relationship between the calorific value and the carbonization temperature of the charcoal produced by the briquette making machine is as follows:
The calorific value of charcoal is directly related to the carbonizing temperature and heat preservation time. Under the condition of same carbonizing temperature and heat preservation time, the calorific value of different raw materials varies. Generally speaking, the carbon content and calorific value are higher under high carbonizing temperature and long heat preservation time. When the carbonizing temperature is lower than 450℃, the calorific value of charcoal made from wood and leftover materials is usually 6500 ~ 7000kcal/kg and the calorific value of charcoal made from  straw and rice husk is commonly 6000kcal/kg. When the carbonizing temperature is higher than 600℃, the calorific value can be improved by 500 ~ 1000kilocalorie.
