How much does it cost to build a small and medium-sized commercial biomass pellet plant? The specific investment cost depends on the hourly production output. The greater the output, the higher the investment, there is no doubt. The following is an example of a biomass pellet fuel production line with an annual output of 1,000 tons/year of wood chips and agricultural and forestry waste to introduce the specific investment and equipment configuration. The situation in each country is different. Take China's biomass pellet factory as an example.

Small and Medium-sized Commercial Biomass Pellet Plant

1. Small and Medium-sized Commercial Biomass Pellet Plant Project Overview

The project has an investment of 800,000 RMB and covers an area of ​​19314 square meters. It is mainly equipped with a biomass pellet fuel production line, which produces 1,000 tons of pellet fuel annually.

6. Project labor quota and work system of Commercial Biomass Pellet Plant Project

There are 15 production employees in the project, 8 of whom are boarding and lodging in the factory area, and 7 are not living in the factory area. Work system: The staff of this project are all in one-shift system, and the production is 300 days a year and 8 hours a day.

7. Process flow of Small and Medium-sized Commercial Biomass Pellet Mill Project

Brief description of process flow

(1) The project purchases wood scraps from wood processing plants, waste mushroom sticks from the mushroom stick factory, and crop waste collected from farmland (paddy stalks, peanut shells, walnut shells, etc.) as raw materials.

(2) The raw materials are sliced, screened, and crushed by a wood hammer mill. The crushing stage mainly generates dust and noise.

(3) Due to the high moisture content in the raw materials, the feed conditions of the biomass pellet machine cannot be met, and the materials need to be dried. The crushed raw materials are then burned with biomass fuel through a Rotary Drum Drying machine. The biomass pellet fuel enters the high-temperature combustion chamber through the automatic feeding system, where high-temperature combustion occurs rapidly in the high-temperature combustion chamber. This stage mainly produces noise, flue gas and furnace ash.

(4) After drying, the material is conveyed to the granulator by a conveyor belt, and is fed by the leucorrhea feeding device of the granulator. The biomass raw material is sent to the feeding chamber of the molding machine, and the material is shared by the distributor and the scraper. It is evenly spread on the ring die under the action, and then the material is squeezed into the die hole. The material undergoes forming and shape retention processes in the die hole. Due to the increase in pressure in the molding machine, the particles themselves deform and plastically flow, and generate a lot of heat under the action of friction, which causes the lignin contained in the raw materials to soften, increase the adhesion, and the softened lignin and the inherent in biomass The combined effect of cellulose makes the biomass gradually shape, and after a certain period of time, it is extruded in a cylindrical shape. The rotating cutter cuts the material to form a cylindrical shape and sends it out through the discharge port. In this project, no binder is added during the compression molding process, and noise is mainly produced at this stage.

(5) After granulation, the granules are packaged after natural cooling. The packaging stage mainly produces packaging waste and unqualified products.

(6) The packaged product can be sold outside.
