The Mineral charcoal coal powder briquetting machine is mainly used for pressing lignite, coal powder, iron powder, coking coal, aluminum powder, iron filings, iron oxide scale, carbon powder, carbon powder, slag, gypsum, tailings, sludge, kaolin, activated carbon, coke powder, etc.
All kinds of powder, powder, waste, waste residue are widely used in refractory, power plant, metallurgy, chemical industry, energy, transportation, heating and other industries. The utilization rate of waste has good economic and social benefits.
The mineral charcoal coal powder briquetting machine consists of three parts: the feeding part; the transmission part; the forming part.1. The feeding part is mainly to realize quantitative feeding to ensure that the material enters the pair of rollers evenly. The screw feeding device is driven by an electromagnetic speed-regulating motor, and is rotated by a pulley and a worm reducer to force the material to be pressed into the main feeding port.
Due to the constant-torque characteristics of the electromagnetic speed-regulating motor, when the pressing material amount of the screw feeder is equal to the material amount required by the main machine, a constant feeding pressure can be maintained to stabilize the quality of the pellets. If the feeding amount is too large, the electricity of the feeding device will be overloaded; if the feeding amount is too small, the ball will not be formed. Therefore, skilled operation is an important condition to ensure the normal operation of the pressure ball.
2. In the transmission part, the main transmission system of mineral charcoal coal powder briquetting machine is: motor -- triangle belt -- reducer -- open gear -- roller. The main engine is powered by an electromagnetic speed-regulating motor, and is transmitted to the driving shaft through a pulley, a cylindrical gear reducer, and a rod-pin coupling.
The drive shaft and the driven shaft run synchronously through open gears. A hydraulic device is installed behind the passive bearing housing. The hydraulic protection device is driven by the hydraulic pump to drive the high pressure oil into the hydraulic cylinder to make the piston produce axial displacement. The front end of the piston rod rests on the bearing housing to meet production pressure requirements.
3. The forming part mainly refers to the host part of mineral charcoal coal powder briquetting machine, and the core part is the roller.
When too much material is fed between the two pressure rollers or a metal block enters, the piston rod of the hydraulic cylinder is overloaded by pressure, the hydraulic pump will stop, the accumulator will buffer the pressure change, the relief valve will open to return oil, and the piston rod will shift.
Increase the gap between the rollers so that hard objects pass through the rollers, and the system pressure returns to normal, which can protect the rollers from damage.
