What is the main structure of the biomass pellet machine? The main machine is mainly composed of feeding, stirring, granulating, transmission and lubrication systems. The working process is that the mixed powder (except special materials) with a moisture content of not more than 15% is entered from the hopper into the feeding auger, and the appropriate material flow is obtained by adjusting the speed of the stepless speed regulating motor, and then enters the agitator and passes through the mixer. The stirring rod stirs through the optional iron suction device to remove the iron impurities mixed in the powder, and finally enters the pressing chamber of the granulator for granulation.
feeder
The feeder is composed of a speed regulating motor, a reducer, a auger cylinder and a auger shaft. The speed regulating motor is composed of three-phase asynchronous AC motor, eddy current clutch and tachogenerator. It is used in conjunction with the JZT controller, and its output speed can be changed through the JDIA electromagnetic speed regulating motor controller.
reducer
The feeding reducer adopts a cycloidal pinwheel reducer with a reduction ratio of 1.10, which is directly connected with the speed regulating motor to reduce the speed, so that the effective speed of the feeding auger is controlled between 12 and 120 rpm.
feeding auger
The feeding auger consists of auger barrel, auger shaft and bearing with seat. The auger plays the role of feeding, and the speed is adjustable, that is, the feeding amount is variable, so as to achieve the rated current and output. The auger shaft can be pulled out from the right end of the auger cylinder for cleaning and maintenance.
Granulator press room
The main working parts of the pressing chamber of the biomass pellet machine are composed of a pressing die, a pressing roller, a feeding scraper, a cutter and a screw for adjusting the gap between the die and roller. The wood powder is fed into the two pressing areas through the die cover and the feeding scraper, and the hollow shaft drive wheel drives the die to rotate. The wood powder is drawn between the die and the roller, and the two relatively rotating parts The wood powder is gradually extruded, squeezed into the die hole, formed in the die hole, and continuously extruded to the outer end of the die hole, and then the formed particles are cut into the required length by the cutter, and finally the formed particles flow out of the machine. . The pressure roller is fixed on the pressure roller shaft through two bearings, the inner end of the pressure roller shaft is fixed with the main shaft through the bushing, and the outer end is fixed with the pressure plate. The pressure roller shaft is eccentric, and the die roller gap can be changed by rotating the pressure roller shaft. The adjustment of the gap is realized by rotating the gap adjustment wheel.

Features of biomass pellet machine:

The mold is laid flat, the mouth is upward, and directly enters the pelletizing mold from top to bottom. The specific gravity of the sawdust is very light, straight up and down. After the sawdust enters, it is rotated and thrown around by the pressing wheel to evenly suppress the particles.

The vertical ring die sawdust pellet machine is open upwards, which is easy to dissipate heat. In addition, it also comes with a set of air-cooled cloth bags for dust removal and automatic refueling. The pellet machine is a solid large shaft and a large cast steel bearing seat. Its large bearing does not bear any pressure, is not easy to break, and has a long life.

1. The mold is vertical, feeding vertically, without arching, and is equipped with an air cooling system, which is easy to dissipate heat.

2. The mold is stationary, the pressure roller rotates, the material is centrifuged, and the periphery is evenly distributed.

3. The mold has two layers, which can be used for both purposes, high output and energy saving.

4. Independent lubrication, high pressure filtration, clean and smooth.

5. Independent discharge device to ensure the molding rate of granulation
