The ultimate guide – learn about the biomass pellet making machine
Biomass pellets introduction
Biomass pellet fuel is made by biomass pellet machine. It has the characteristics of environmental protection, cleanliness, high heat, and sufficient raw materials. Wide range of raw materials, including straw, corn stalks, cotton stalks, rape stalks, wheat straw, sesame stalks and other agricultural residues; and forestry wastes such as orchard pruning residues, municipal pruning residues, and garden industry residues.
The high pressure and high temperature in the granulation equipment turn these raw materials into granules, and then cut into small pieces by scrapers. The end result is a clean, environmentally friendly, recyclable high-quality biomass pellet fuel.
The final pellets are suitable for schools, enterprises and institutions, biomass boilers, heating furnaces, vaporizers, bathing, washing, printing and dyeing, textiles, food, spraying, clothing, heating enterprises and other industries.
Introduction of Biomass Pellets Production Process
Biomass pellet fuel production steps: raw material processing, drying, granulation, cooling, packaging. At the same time, each link is equipped with a strict quality control system to ensure the quality of the products.

Biomass Pellet Production Process
Chipping machine
Chippers process logs into small wood chips., and the chipped wood chips are output through the conveyor, and the output materials are stacked or transported through the conveyor to the shredder for next production.
Grinding machine
The shredded chips are transported to the grinding machine through a conveyor for pulverization. After the pulverized material reaches the standard of compressed particles, it is stacked or transported to the dryer through a conveyor for the next step of production.
Drying machine
Biomass pellets have strict requirements on the moisture content of raw materials. Usually, the moisture content should be below 15%. So, we need to use a professional and dedicated dryer, transport high-moisture raw materials to the dryer through a conveyor, and then dry them with hot air. After reaching the specified standard, the next step of production can be carried out.
Characteristics of RICHI Biomass Pellet Making Machine
- Lubrication: The pressure roller, main shaft, and other assemblies are all dust-free precision assembly, using high wear resistance and multi-sealing, spray-type thin oil circulation lubrication, no need to add butter or grease, directly reducing fuel consumption costs.
- Motor: The industry’s first dedicated motor for wood pellet machine, the power output efficiency is increased by more than 10%, the power density of each center height can reach 3-5 times, the voltage and frequency have a wide range, and it is more suitable for operation under harsh environmental conditions and energy saving, safe and stable.
- Transmission: reducer, a special reducer for pellet machine developed and produced by ourselves, shields the short board of ordinary industrial reducer in the operation of pellet machine, adopts finite element design, parallel hard tooth surface gear transmission, and has equal strength step by step. Even if the high temperature, lack of oil, or load increases to 3-4 times normal, it can still operate normally.
- Safety: The lubrication level of the whole machine is designed based on the lower maximum allowable oil temperature, and the loading cycle is forced to air cooling, the oil temperature is low and constant, and the spray lubrication shields the characteristics of short-term deterioration caused by the agitation of the lubricating oil, and the oil replacement cycle Extend 1.5 times.
- Modularization: To break the situation that the biomass pellet machine in the industry adopts ordinary motors and ordinary industrial reducers, and use self-developed pellet machine special motors and reducers to provide power and transmission. The design of the whole machine becomes more compact, the complex process and small parts are reduced, the modular production and assembly of standard parts are realized, and the quality, performance, and safety factor of stable operation are increased by 3-4 times.

Cooling machine
The temperature of the pellets during compression molding is as high as 80~90℃, the structure is relatively loose, and it is easy to be broken. After being cooled to room temperature by a cooler, the pellets have high strength and are not easily broken before they can be bagged into the warehouse or sent into the drum by conveyor and elevator. The warehouse proceeds to the next step.
Packing machine
The sieved finished biomass pellet fuel is transported to the packaging machine for packaging via a conveyor. It can be packaged in 25KG, 50KG and ton bags, and then placed in inventory for sale.
