How does the briquetting machine work?

The briquetting machine is composed of a pressing shaft assembly, a frame, a pre-press, a hydraulic system, a coupling, a reducer, and a motor. According to the function of each part, it can be divided into three parts: feeding, transmission, and forming. Each of the different parts has a vital influence on the forming of the briquetting machine. Zhongyuan Mine is a high-pressure briquetting machine, The manufacturer of ultra-high pressure briquetting machine has many years of experience in the structural design of briquetting machine, and will explain in detail the composition of these three parts and the operating principle of the briquetting machine.

Composition of briquetting machine

1. The feeding part is mainly to realize quantitative feeding to ensure that the material evenly enters the roller room. The screw feeding device is driven by a speed-regulating motor, and is rotated by a belt pulley and a worm reducer to force the pressed material into the main feed inlet. Due to the constant moment of the speed-regulating motor, when the pressure amount of the screw feeder is equal to the amount of material required by the host, a constant feeding pressure can be maintained to stabilize the pellet quality. If the feeding amount is too large, the electric power of the feeding device will be overloaded; if the feeding amount is too small, the ball will not be formed. Therefore, skilled operation techniques are an important condition to ensure the normal work of the pressure ball.

2. In the transmission part, the main transmission system is: motor-coupling-synchronous reducer-roller. The main engine is powered by a speed-regulating motor, which is transmitted to two pressure rollers via a synchronous reducer. A hydraulic device is installed behind the movable 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 the production pressure requirements.

3. The forming part mainly refers to the main machine part, and the core part is the pressing roller. When there is too much feed between the two pressure rollers or metal blocks, the piston rod of the hydraulic cylinder is overloaded, the hydraulic pump will stop, the accumulator will buffer the pressure change, the overflow valve will open to return oil, and the piston rod will shift Enlarge the gap between the pressure rollers so that the hard objects can pass through the pressure roller, and the system pressure will return to normal, which can protect the pressure roller from damage. This machine can adjust the pressure according to the requirements of the pressure ball density, and the production is flexible and flexible.

Working principle of briquetting machine

In order to make the material into a ball under high pressure, a pre-compression screw is used to force the material to be formed into the middle of the counter roller. Due to the constant speed and reverse rotation, the material is compressed and formed. The unit pressure is from small to large until the centerline of the counter roller is "0-0". At this point, the molding unit pressure reaches the maximum value. As the counter roller continues to rotate, the molding pressure continues to decrease, and it enters the ball-off state until the ball is off.

Among them, the main engine is powered by an electromagnetic speed regulating motor, which is transmitted to the driving shaft through a rod-pin coupling through a belt pulley, a cylindrical gear reducer. The driving shaft and the driven shaft are ensured to run synchronously through open gears. A hydraulic device is installed behind the passive bearing seat. The screw feeding device is driven by an electromagnetic speed-regulating motor, and is rotated by a belt pulley and a 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 pressure of the screw feeder is equal to the amount of material required by the host, a constant supply pressure can be maintained to stabilize the pellet quality. If the feeding amount is too large, the feeding device will be overloaded; if the feeding amount is too small, the ball will not be formed. Therefore, skilled operation techniques are an important condition to ensure the normal operation of the energy-saving briquetting machine.

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 the production pressure requirements. When there is too much feed between the two pressure rollers or metal blocks, the piston rod of the hydraulic cylinder is overloaded, the hydraulic pump will stop, the accumulator will buffer the pressure change, the overflow valve will open to return oil, and the piston rod will shift Enlarge the gap between the pressure rollers so that the hard objects can pass through the pressure roller, and the system pressure will return to normal, which can protect the pressure roller from damage. Kaizheng environmental protection machine can adjust the pressure according to the requirements of the pressure ball density, and the production is flexible and flexible.

Analysis of working principle of briquetting machine

It can be seen from the working principle that the quality of the pressed ball blank is directly related to the spiral shape, speed, pre-pressure, etc., when the host-to-roller speed is fixed, so the pre-compression screw speed must be adjustable, and at the same time, it is related to the nature of the powder. The particle size and pelletizing process (dry and wet method) have a greater impact. Generally speaking, wet molding is easy. For dry molding, due to the large compression ratio of raw materials, it takes many times to press molding. Therefore, when dry molding is used, new The pressing process of feeding and returning the material can continuously and stably produce and ensure the quality of pellets.

How does the briquetting machine work

1. The material enters the forming machine hopper evenly from the storage bin through the quantitative equipment, and is adjusted by the adjusting gate on the hopper to make the material evenly enter the middle of the roller.

2. The unit molding pressure of the material that is compressed by the rollers with the constant speed and reverse rotation is changed from small to large, and the molding pressure reaches a large value at the center line of the pair of rollers. After the material passes the line, the molding pressure decreases rapidly so that the material enters The state of the ball.

The above is all about the working principle of the briquetting machine. Only by understanding its working principle in detail can the briquetting machine be operated more efficiently and safely.
