10,000 Tons/year large-scale sawdust rice husk pellet machine production line project, that is, 4t/h rice husk sawdust biomass pellet production line project. Only one is calculated based on annual output, and one is calculated based on hourly output. The project's raw materials are also very abundant, including wood chips, rice husks, branches, leftovers and waste. Of course, such a large-scale project requires a lot of equipment, among which the host equipment includes a grinder, a crusher, a biomass pellet machine, a drum dryer, and a belt conveyor.

Biomass solidified compact molding fuel uses wood chips, rice husks, etc. as raw materials. After pressurized molding, the volume decreases exponentially, the combustion is fierce, the combustion time is long, the amount of combustion pollutants is small, and the residue after combustion is still used to produce potash fertilizer The raw materials are basically free of residue. The product of the project is a solid briquette with an annual output of about 10,000 tons and a diameter of about 12mm.

I. Project Construction Overview

The project covers an area of ​​5000m2, with a total construction area of ​​1500m2. The main construction content includes production workshop, warehouse workshop, raw material storage yard, and office area. The main structures of the project are shown in Table 1, and the main equipment of the project is shown in Table 2.

II. Brief Description of Production Process

(1) Crushing: Due to the large size of various types of raw materials, they need to be crushed to 600mm by a crusher, and then directly transported to the airtight molding machine to be directly pressed into shape by pressure. This process generates dust G1 and noise N.

(2) Drying: Because the moisture in the raw materials may not meet the production requirements, the raw materials need to be dried. The drying process of this project uses biomass pellet fuel as energy. This process produces particulate matter, SO2, and NOXG2.

(3) Press molding: The dried straw material and saw foam are fed into the biomass pellet machine in a certain proportion, and compressed into the pellet shape in the pellet machine without any additives. The pellet machine is sealed. This process produces noise.

(4) Packing and storage: the qualified finished products produced are bagged and weighed, then packed, and stored in storage.

III. Number of Employees and Work System

Labor quota: The project has a labor quota of 6 people, none of whom live in the factory. The production shift is a one-shift system with 8 hours of work per shift and 300 days of work per year.
