Coal ball press machine

The coal pellet press can be used to press various coal powder like materials such as coal powder, coking coal, charcoal powder, coal slurry, coke powder, and coke powder. The materials produced by the coal pellet press are energy-saving, environmentally friendly, easy to transport, and improve the utilization rate of waste materials, with good economic and social benefits.

The coal pellet press machine consists of three parts: first, the feeding part; 2、 Transmission part; 3、 Forming part
1、 The feeding part mainly achieves quantitative feeding to ensure that the material enters the roller room evenly. The spiral feeding device is driven by an electromagnetic speed regulating motor, which rotates through a pulley and a worm reducer to force the compressed material into the main feeding port. Due to the constant torque characteristic of the electromagnetic speed regulating motor, when the pressing amount of the screw feeder is equal to the required material amount of the host, a constant feeding pressure can be maintained to stabilize the quality of the pellets. If the feeding amount is too large, the electrical overload of the feeding device will occur; If the feeding amount is too small, it will not form balls. Therefore, proficient operation skills are an important condition for ensuring the normal operation of the ball press.
2、 The transmission part, the main transmission system is: electric motor - triangular belt - reducer - open gear - rolling mill. The host is powered by an electromagnetic speed regulating motor, which is transmitted to the drive shaft through a belt pulley, cylindrical gear reducer, and rod pin coupling. The active shaft and passive shaft operate synchronously through open gears. A hydraulic device is installed behind the passive bearing seat. The hydraulic protection device is driven by a hydraulic pump to inject high-pressure oil into the hydraulic cylinder, causing axial displacement of the piston. The front connecting head of the piston rod is placed on the bearing seat to meet the production pressure requirements.
3、 The forming part mainly refers to the main engine part, and the core part is the rolling mill. When too much material is fed between the two pressure rollers or enters the metal block, the hydraulic cylinder piston rod is overloaded under pressure, the hydraulic pump will stop, the accumulator will buffer the pressure change, the overflow valve will open to return oil, and the displacement of the piston rod will increase the gap between the pressure rollers, allowing hard objects to pass through the pressure rollers. The system pressure returns to normal and can protect the pressure rollers from damage. This machine can adjust the pressure according to the requirements of the ball pressing density, and the production is flexible and agile.

When the coal pellet press machine is working, the main engine is powered by an electromagnetic speed regulating motor, which is transmitted to the driving shaft through a belt pulley, cylindrical gear reducer, and rod pin coupling. The active shaft and passive shaft operate synchronously through open gears. A hydraulic device is installed behind the passive bearing seat. The spiral feeding device is driven by an electromagnetic speed regulating motor, which rotates through a pulley and a worm reducer to force the compressed material into the main feeding port.

If the feeding amount is too large, the electrical overload of the feeding device will occur; If the feeding amount is too small, it will not form balls. Therefore, proficient operation skills are an important condition for ensuring the normal operation of the ball press.
