Working principle
The electric motor supplies the power to drive the driving shaft to rotate through the belt pulley and coupling. At the same time, the driven shaft also rotates against the driving shaft by the gear wheels. The rollers, which are set in the driving and driven shafts rotate synchronously. When the coal materials are fed into the machine and fall down to the place between the two rollers, all the coal powders will be forced into briquettes between the two squeezing rollers with the high pressure, which generates from the two rollers. While each two holes from the two rollers tough each other the pressure will reach to the peak value. As the two holes separate and the pressure becomes less to zero. When the pressure comes to zero, the briquettes will fall down and be discharged from the machine.

Application
The finished briquettes are mostly used in power plant, heating industry, energy field, metallurgical industry, etc. The blocks/briquettes produced by coal briquette press are environmental and energy-efficient, and also are convenient for transportation and reloading, and therefore the utilization of wasted powder materials are increased highly for end users.
