Most of the briquette machine has three heating coils. The power of each heating coil is 1.5kw. The main function of the heating coil is to carbonize the surface of the briquettes extruded and squeeze out lignin from the raw material, bond the raw material into a briquette of uniform density.

The heating coil on briquette machine is not only used for heating. It can make the temperature of the propeller rise in extrusion process to make the lignin inside the raw material adhesive after high temperature heating. If there is no heating coil, the briquettes produced would be loose and uneven in density, and in the process of burning, it would become broken charcoal.
The briquette machine has achieved the goal of turning waste into treasure, saving energy and preventing pollution. The operation of briquette machine requires a certain skill. In the working process of briquette machine, the temperature need to be controlled. The machine should heat gradually. Too high or too low temperature is adverse. Meanwhile, the moisture content of the raw material also need to adjusted between 8-12%. 
Briquette machine uses the screw extrusion principle to compress materials prepared into prismatic hollow briquettes with a certain intensity. The biggest advantage of the briquette machine is that it can take almost all of the plant or material containing wood fiber as raw materials, mainly including sawdust, rice husk, seed shell, walnut peel, branches, bark, trunk, vinegar residue, furfural residue, peanut shell and various crops straw, etc. Raw materials come from a wide range of sources and they are quite cheap.
