As a new type of pellet fuel, biomass pellets have won wide recognition for their unique advantages. Compared with traditional fuels, biomass pellets made by biomass fuel pellet plant not only have economic advantages but also environmental protection benefits, and fully meet the requirements of sustainable development.
The raw materials of biomass pellets are mainly crop straws, straws, waste wood scraps and other wastes. The processed biomass pellets are small in size, high in density, resistant to combustion, easy to store and transport, and the calorific value can reach 3200~4500 kcal, which is ideal new fuel.
In this background, the client of this cheap price small biomass pellet plant project, Yongzhou Xinxin Waste Processing Plant, invested 2 million RMB (313000USD) to build a 1500t/year small biomass sawdust pellet plant project in the local area.
The small biomass wood pellet plant project leased a local smelter that failed. This time, an original factory plant and other auxiliary projects (office rooms, dormitories, canteens) were used to construct the 1500t/year sawdust biomass pellet plant project.
This 600-700kg per hour small biomass sawdust pellet plant project is a new project. The small biomass pellet mill plant project uses the original factory building for production.
The construction period of this small biomass pellet mill plant project is mainly to adjust its workshop layout and wood pellet equipment installation and commissioning. There is no earthwork and the construction period is short. The total construction area of the small biomass pellet mill plant project is 1550m².
Workshop of the small wood pellet plant
The main construction content of the 600-700kg per hour small biomass sawdust pellet mill plant project is the production workshop, raw material storage area, office area, dormitory, and canteen. (Project office buildings, production workshops, canteens and dormitories all use the existing projects in the plant area and make reasonable transformations according to requirements).

The main raw materials used in the sawdust wood biomass pellet plant project and the annual energy consumption are shown in the following table:
| Name | Annual consumption | Remarks |
|---|---|---|
| Wood sawdust | 1550t | Recycling in the surrounding area |
| Water | 174m3 | / |
| Electricity | 300KW.h | / |
| Formed biomass pellets | 100t | As fuel for hot blast stove |
| Packaging bag | 1500 pcs | Outsourcing |
The main biomass fuel making machinery list of the small biomass sawdust pelletizing plant project is detailed in the following table:
| Name | Specification model | Quantity |
|---|---|---|
| Pellet plant use sawdust dryer | QHG150X | 1 unit |
| Hot blast stove | / | 1 unit |
| Bucket elevator | TDTG40/23 | 2 units |
| Sawdust pellet press | MZLH320 | 2 set |
Due to the different sources of purchase, the moisture content of the purchased sawn wood ash is high due to rain wet or irregular stacking. In order to ensure the quality of the product, a dryer is required to dry the raw materials to make the moisture content. It meets the pelleting requirements (the moisture content is less than 15%).
The sawdust dryer in pellet production line 600-700kg/h project is equipped with a biomass hot blast stove, and the heat source is biomass pellet fuel. The raw material drying process will evaporate part of the water vapor, which accounts for about 3% of the raw material consumption.
The amount of raw material to be dried in the biomass fuel wood sawdust pellet plant project is about 1300t/a, and 39t/a of water vapor is generated. The hot blast stove is used for 2 hours a day, and the annual working time is 300 days.
The sawn wood ash is transported to the biomass pelletizer by a hoist. The hoist shell is made of seamless steel pipe with good sealing performance. The motor is driven by the reducer to rotate the spiral, and the material is transported along the fixed casing through the rotation.
The dried raw materials are sent to the granulating machine through the elevator to be granulated by biomass fuel wood pellet machine. The temperature in the biomass pelleting machine is controlled at 110~120℃, and the moisture in the raw material itself is not completely dried to press it into granules.
2 Sets of wood pellets making machine
The good stability ring die wood sawdust biomass wood pellet mill pressurizes the uniformly stirred raw materials into sawdust pellets. Through the compression of external force, the lower pressure is transmitted to the biofuel pellets, so that the arrangement structure of the loosely stacked solid particles begins to change, and the inside of the biomass gap is reduced.
The extruded material is formed at the exit of the biomass wood pellet machine. The whole biomass pellet plant process is physical extrusion without adding any binder.
The biomass pellets formed by the biomass pellet machine palnt 600-700 kg hr project are naturally cooled and sold through artificial packaging.
The easy to use small biomass pellet plant project site is far away from the surrounding environmental protection targets, so the impact on the surrounding acoustic environment is small. However, the location of the small sawdust biomass pelleting plant project has very strict requirements for noise, so in terms of design, we adopted the following plans:
