The ring die wood pellet making machine is based on rice husks, peanut shells, melon seed shells, bamboo chips, bagasse, palm shells, branches, branches, bark, leaves, wood scraps; large furniture factories, wood factories, various Sawdust produced from wood, etc., are used as raw materials to be processed into equipment that will replace coal in renewable fuel pellets in the future.
1. CE wood pellet mill features:
（1）It is widely used for pelletizing of light substances, such as wood chips, sawdust, straw, pasture, chrysanthemum, palm leaf and so on;
（2）The feeder's especial structure makes materials conveyed evenly. It is specially designed for pelletizing of light substances with the density of 0.15-0.65g/cm3;
（3）Feeder,conditioner and chute are made of stainless steel with long service life;
（4）It is with magnet and over load protection system which can protect machine well during production;
（5）It makes gear directly-connecting as the driver and is with quick-release die fixed by clamps,which can increase the output by 15% more than the same type machine with belt-convey;
（6）The bearings and oil seals in the main drivers are imported from Japan to ensure highly-efficient,stability and credibility.
2. Biomass wood pellet application:
（1）Civilian heating:high use ratio and easily
（2）Biomass industrial boiler:be used as the main fuel of the industrial boiler,solve the problem of environmental pollution.
（3）Power generation:be as the fuel of thermal power generation.
3. The working principle of the ring die wood pellet machine for sale:
The working principle of the ring die sawdust pellet machine is: when the ring die sawdust pellet machine is working and the conveyor device of the pellet machine is working, the material will be transported by the conveyor device, pass through the bin to be pelletized, and then enter the modulator Perform modulation processing. In this process, the material and the honey added with the material are added to the grease either through steam or with the material. It can be achieved by stirring during the treatment. Then the material will undergo a conditioning treatment. In the conditioning process, the material conditioning treatment method includes wet heat treatment. After the above steps, the material will enter the pellet machine through other conveying devices for the next operation.
When the material enters the pellet machine, the material will rotate in the ring die. And the material will be subjected to centrifugal force. Later, the material will be evenly divided between the mold rolls after the modulation process. Between the die rolls, the material will be squeezed and stuffed under the rotation of the die rolls. In the later stage of material production, the shape of the material will become a strip shape under the extrusion of the die hole. Since the length of the cutter installed on the outside of the die is a fixed length, the material is produced after the end of production. The material will become material particles of corresponding length under the cutting work of the corresponding cutter length.
4. Design of the wood pellet press machine die and roller
The ring die of the bbiomass wood pellet manufacturing machine is generally made of high-quality alloy steel, chromium steel and carburized stainless steel, the latter material is better. The production is to first calcinate or roll the steel into a blank, turn and drill, and then perform nitriding treatment. The surface hardness reaches 53-49HRC, and the inner wall of the die hole reaches a roughness of 1.6. The ring die aperture of the ring mode pellet machine designed this time is 5mm.
The shape of the die hole includes straight holes, stepped holes, outer cone holes, inner micro holes, etc.: The size of the die hole is determined by the diameter of the die hole. Apertures can generally be divided into two categories, one is small inside and large outside, and this type is used for die holes with a diameter of less than 10 mm. The other is large inside and small outside, this is the hole diameter of the die is greater than 10 mm.
When dealing with different feed quality, the way and conditions of the pellet machine to choose the compression mold during the compression process are not only based on the size of the pore size. Under the condition that the quality of the feed is relatively high, the corresponding better thickness of the die can be selected. The thickness of the commonly used die is in the range of 32-127 mm. Looking up relevant information, the diameter of the die hole of the compound feed containing grain is generally 5 mm, and the wall thickness of the die is generally 57 mm, the smaller is 45 mm, and the average diameter is 50 mm.
