The reason for low density of briquettes in briquette machine production

In the production process of briquette machine, the higher the density and compactness of the briquettes produced by the briquette machine, the better the quality of the charcoal produced. What’s the reason for low density of briquettes in the production? Generally, the temperature for making briquettes is about 370°. Low density of briquettes may be related to the temperature in the production. While the low density of briquettes may also caused by that the raw materials are not dried to the required moisture content. Then, users need to find the key to the problem, including adjust the propeller appropriately, check whether the temperature of wood briquette machine is up to standard and whether raw materials are dried to the appropriate temperature.



The water content, particle size uniformity and temperature of raw materials are directly related. The density of briquettes also has relations with the density of raw materials. If the miscellaneous wood, pine, willow are used as raw materials, then the density of briquettes produced is 1.8. After cooling for half an hour, the density of briquettes can reach 2.1. While the density of briquettes taking the straw, corn stalk, cotton stalk and bean stalk as raw materials is 1.4.

The abnormal briquette production of the briquette machine is generally related to the humidity of raw materials, the length of screw in the sleeve (mating clearance) and heating temperature of wood briquette machine in briquettes making process.
