The Main Structure And Working Principle Of Biomass Pellet Machine

May 09, 2022

The main structure and working principle of biomass pellet machine:


The biomass pellet machine is mainly composed of five parts: a feeder, a conditioner, a pellet maker, a conditioning mechanism, and a smoothing system.
    The feeder is composed of a variable frequency speed-regulating motor, a transmission device, a reducer, an auger shaft, an auger shell, etc. Its effect is to provide a suitable feeding amount for the conditioner. The conditioner is composed of a motor, the main shaft, a conditioning rotor, a casing, and a steam inlet. Its primary function is to introduce steam to temper a certain amount of mixed material to a certain temperature and humidity to improve the material. The granulation characteristics are then sent to the granulator for granulation. 508 granulator The granulator, also known as the granulation chamber, mainly consists of the main motor, the transmission mechanism, the rotor, the ring die, the pressing roller, the scraper, the cutter assembly, and the fuselage. The quenched and tempered material is evenly fed into the area between the ring die and the two pressing rollers by the deflecting scraper on the front plate and the rotating feeding cone. With the relative rotation of the ring die and the pressing roller, the material is gradually It is extruded into the hole of the ring die, continuously extruded to the outside to form strip-shaped pellets, and finally cut into the required length pellets by the cutter.

According to the different conditions of the powder material when it is kneaded by the die roller, it is divided into three areas: the feeding area, the deformation and pressing area, and the kneading and forming area.
     Feeding area: In this area, the material is hardly affected by any mechanical external force. However, because the ring die rotates counterclockwise under the action of the rotor, the material is affected by centrifugal force and adheres to the inner and outer surfaces of the ring die.
     Deformation and compaction area: Entering this area, the gap between the die rolls gradually becomes smaller, the material is subjected to increasing kneading force, and the powder begins to undergo relative displacement, some of which have entered the die hole, resulting in irreversible plastic deformation.
     Kneading and forming area: In the kneading area, the gap between the die rolls reaches the minimum, and the kneading force gradually increases, so the contact area between the powder particles increases and bonds together. When the kneading force reaches enough to resist the friction between the material and the die hole, the material is thoroughly kneaded into the die hole.
