3.5 Tons/hour Rice Husk Wood Pellet Production Line Project

The construction project of a production line for forming Wood pellets with an annual output of 5,000 tons, with an hourly output of 3.5 tons/hour, using a set of MZLH858 pelletizing equipment. The MZLH858 ring die pellet machine produces 3-4.5t/h. In addition, Including crushers, dryers, coolers, screening systems, packing systems, feeders, fans, coolers, etc.

3.5 Tons/hour Rice Husk Wood Pellet Production Line Project

I. Wood Pellet Production Line Project

• Project name: 3.5 tons/hour wood rice husk pellet production line project
• Project annual output: 5000 tons/year wood pellet production line project
• Project location: Heshan District, Yiyang City
• Construction nature: expansion
• Area: 1230 square meters
• Total project investment: 640,055 million yuan

This project is located in Jintang Village, Lanxi Town, Heshan District, Yiyang City. It uses the existing vacant workshops to build a new molding wood pellet production line with a production scale of 5,000 tons/year, which mainly includes a production workshop and a finished product warehouse. Purchase a set of MZLH858 pelletizing production equipment, which can produce Wood pellets with a capacity of 3.5 tons per hour. These include granulators, feeders, fans, coolers, etc. The total investment of the project is RMB 640,55 million to build a production line for forming wood pellets. For a list of construction project composition, see Table 1-1.

II. Process Flow of Wood Rice Husk Pellet Production Line

1. Raw materials: The raw materials are taken from the rice production line and transported to the granulator through a closed duct. The raw material hopper is installed on the top of the production workshop.

2. Granulation mechanism: The material in the raw material hopper is conveyed to the feed inlet of the granulator due to the action of the center of gravity. Under the conditions of high temperature and high pressure, the water is discharged to the atmosphere in the form of water vapor, and the raw material is compressed into molded wood pellets. It is transported to the next process by belt conveyor. The granulating process adopts electric heating, and the granulating temperature is about 80℃-120°C. This process generates dust.

3. Conveyor belt conveying: After being processed by the pelletizer, the formed wood pellets fall from the discharge port to the belt conveyor, and are conveyed by the belt conveyor to the finished product hopper.

4. Cooling: The temperature of the pellets is as high as 80-90℃ when the pelletizer is discharged, and must be cooled to room temperature before storage. This project adopts air cooling. Since the Wood particles have been compressed and compacted, there is basically no dust generated during the cooling process.

5. Finished product bagging and storage: the bottom of the finished product warehouse is a funnel-shaped discharge port, which is pneumatically discharged. The finished product falls on the conveyor belt, is transported by the conveyor belt to the packaging bag, and is transported to the finished product warehouse by forklift.
