2015 Supply of high-efficiency briquette briquetting machine

Structural composition of coal briquetting machine
The feeding part is mainly to realize quantitative feeding to ensure that the material enters evenly between the rollers. The spiral feeding device is driven by an electromagnetic speed-regulating motor and rotates through a pulley and worm reducer to force the pressed material into the main feed port. Due to the constant torque characteristics of the electromagnetic speed-regulating motor, when the amount of material pressed by the screw feeder is equal to the amount of material required by the host machine, a constant supply pressure can be maintained to stabilize the pellet quality. If the amount of material supplied is too large, the electric overload of the feeding device will cause the ball to form if the amount of material supplied is too small. Therefore, skilled operating skills are an important condition to ensure the normal operation of the pressure ball.
As for the transmission part, the main transmission system is an electric motor triangle belt reducer open gear roller. The main engine is powered by an electromagnetic speed-regulating motor, passed through a pulley cylindrical gear reducer, and transmitted to the driving shaft through a pin coupling. The driving shaft and the driven shaft ensure synchronous operation through open gears. A hydraulic device is installed behind the passive bearing seat. The hydraulic protection device uses a hydraulic pump to drive high-pressure oil into the hydraulic cylinder, causing the piston to produce axial displacement. The front joint of the piston rod rests on the bearing seat to meet production pressure requirements.
The forming part mainly refers to the main part of the briquette machine, and the core part is the roller. When too much material is fed between the two pressure rollers or the metal block enters, the piston rod of the hydraulic cylinder is overloaded and the hydraulic pump will shut down. The accumulator will buffer the pressure change and the overflow valve will open to return oil. The piston rod will shift and the pressure roller will move. The gap between them is enlarged to allow hard objects to pass through the pressure roller, and the system pressure returns to normal, which can protect the pressure roller from damage. This machine can adjust the pressure according to the requirements of the ball density, and the production is flexible.
