Pulverized coal briquetting machine is widely used. It can briquette, granulate or press the following materials, such as aluminum chips, activated carbon, alumina, bauxite, caustic sodium, charcoal, clay, coke chips, coal, cryolite, chemical fertilizer, plastic, limestone, pigment, urea, potassium salt and other materials. It has the function of one machine with multiple functions.

 

2. Environmental protection and energy saving:

Pulverized coal briquetting machine greatly improves the utilization efficiency of coal resources and reduces the waste of energy in the process of coal combustion. The pressed briquette is fully burned, so the exhaust gas (sulfur dioxide) is very little, and the dust and soot emitted into the air are also greatly reduced.

 

3. Reasonable design

The main machine of pulverized coal ball press is powered by electromagnetic speed regulating motor and transmitted to the driving shaft through belt pulley, cylindrical gear reducer and rod pin coupling. The pressing process can maintain a constant feed pressure and stabilize the pellet quality.

The structure of pulverized coal ball press consists of three parts: feeding part; Transmission part; Forming part.

1. Feeding part

It is mainly to realize quantitative feeding to ensure that the materials enter the counter roll evenly. The screw feeding device is driven by the electromagnetic speed regulating motor and rotates through the belt pulley and worm reducer to force the pressed material into the main feed inlet. Due to the constant torque characteristic of the electromagnetic speed regulating motor, when the pressing amount of the screw feeder is equal to the material amount required by the host, the constant feeding pressure can be maintained to stabilize the pellet quality. If the feeding amount is too large, the electric overload of the feeding device; If the feeding amount is too small, the ball will not be formed. Therefore, skilled operation skill is an important condition to ensure the normal operation of the pressure ball.

 

2. Transmission part

The main drive system is: Motor - triangular belt - reducer - Open Gear - roll. The main engine is powered by the electromagnetic speed regulating motor, which is transmitted to the driving shaft through the belt pulley, cylindrical gear reducer and rod 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 is that the high-pressure oil is pumped into the hydraulic cylinder by the hydraulic pump to make the piston produce axial displacement. The front connecting head of the piston rod is on the bearing seat to meet the production pressure requirements.

 

3. Forming part

It mainly refers to the main engine part, and the core part is the roll. When too much material is fed between the two pressure rollers or enters the metal block, the plug rod of the hydraulic cylinder live ball press is overloaded, the hydraulic pump will stop, the accumulator will buffer the pressure change, the overflow valve will open and return oil, and the piston rod will shift to increase the gap between the pressure rollers, so as to make the hard objects pass through the pressure rollers, and the system pressure returns to normal, which can protect the pressure rollers from damage. Adjust the pressure according to the requirements of pressure ball density, and the production is flexible.

 

Finished ball

The pulverized coal ball press can produce square, ball egg, random circle, goose egg, pillow and other special shaped finished balls. The specific shape and size can be defined by the user. See the following figure for finished product samples:
