Introduction
Briquette machine mainly used for pressing powdery material which are difficult to molding, the character of briquette ball press machine is high molding pressure, main engine revolution adjustable, and with a spiral feeding device. 

Application
Envrionment protection briquette machine mainly used to press all kinds of coal and mineral powder, metal powder, coal powder, coke powder, gypsum, slag, sludge, iron powder, charcoal powder and make them molded. The charateristics are high density, high strength and high hardness. It widely used in refactory, power plants, metallurgy, chemical, engery, transportation. 

Working Principles
Briquette machine is powered by the electromagnetic motor speed control, through the belt pulley, cylindrical gear reducer, to the drive shaft by pin coupling. The driving shaft and the driven shaft be ensured synchronous operation through a gear .there is a hydraulic device behind the Passive bearing seat. Screw feeding driven by electromagnetic motor speed control. Put the material into feeding port through the belt wheel and the worm reducer. Cause the constant of the electromagnetic motor seed control until the weight of the screw feeder is equal to the needed weight, then the constant feeder pressure make the ball with stable quality. but If the feeding quantity is too high will lead to the electrical of the feeder machine overload. And also, it’s not enough to make a ball if the feeding quantity is too small.
