Low Cost High Return 8T/H Wood Pellet Factory Project Report For Agricultural And Forestry Waste

Project overview

Biomass pellet and briquette fuel technology uses wood chips produced in forestry production and processing and waste materials such as crop straws and rice husks generated in agricultural production as raw materials to undergo professional mechanical treatment and compression to produce compact molded fuel pellets.

Mainly used in fireplaces, biomass boilers and various combustion equipment suitable for particulate fuels. It is a new type of environmentally friendly and energy-saving material that replaces coal and diesel.

The customer of this low cost high return 8t/h wood pellet factory for agricultural and forestry waste project, Anhui Yuandong Biomass Fuel Co., Ltd., invested 5 million yuan (785,000 USD) to build a 100,000-ton biomass pellet fuel production project located in Xinhe Town Industrial Park, Anhui Province, China.

In November 2017, the company used self-purchased factory to purchase wood biomass agricultural and forestry waste manufacturing equipment such as feeding screw conveyors and biomass rice husk sawdust straw wood pellet machines. The 8 ton per hour agriculture waste biomass wood pellet factory project is constructed in two phases.

1. In the first phase, a local factory building is rented to build a production line (8T/H) with an annual output of 20,000 tons of biomass fuel pellets;
2. The second phase plans to build a new self-owned factory building through the purchase of land use rights. Increase equipment to increase the annual production capacity to 100,000 tons.

The low investment 8 tons per hour agricultural and forestry waste wood pellet factory project has a labor quota of 10 people, an annual effective production of 300 days, an 8-hour work day during the day, and a total of 2,400 hours of production throughout the year.

It can be calculated that the output of the agricultural and forestry waste wood pellet factory is 42 tons per hour, 8333 tons per month, 333 tons per day. However, the customer's wood pellet factory project is constructed in two phases, so the output of the first phase of the wood pellet factory project we undertook is 8 tons per hour.

In addition, the customer's total investment for the good quality rice husk stalk Biomass Wood Pellet Production Line is 5 million yuan (785,000 USD), and the wood pellet factory equipment investment for the first phase of the project is about 200,000 USD.

Raw material rice husk unloading

Product plan

The product of this field installation provided 8 tons per hour wood pellet factory project is biomass pellets. Use wood sawdust, straws and rice husks to compress and process them into finished pellets. After the complete wood pellet factory project is completed, 100,000 tons of biofuel pellets will be produced annually.

Construction content

This 8tph automatic wood pellet factory project (Phase 1) is located in the factory area with two factories, a one-story steel structure factory building with a construction area of ​​1531.82 m²; a two-story steel concrete structure office building with a construction area of ​​352.91 m². The main construction content of this 8t/h agricultural and forestry waste wood pellet factory project is shown in the table below.

Construction category	Construction name	Construction content and scale
Main Construction	Production workshop	A one-story steel structure building with a total construction area of ​​1531.82m². The wood pellet factory workshop mainly includes a raw material storage room and a pelletizing workshop.
Auxiliary Construction	Office building	A two-story steel-concrete structure, adjacent to the wood pellet factory building, on its west side, with a construction area of ​​352.91m².
Storage and transportation engineering	Raw material warehouse	Set in the wood pellet factory workshop, the building area is about 1000m². The raw materials are directly transported to the wood pellet mill press machine through the feeding auger for processing, and there is no raw material transfer and dosing process, thereby reducing dust pollution.
	Finished product warehouse	The building area is about 200m2, located on the south side of the wood pellet factory production workshop, mainly used for the temporary storage of finished products.
Transportation Engineering	Raw material transportation	The raw materials are transported by trucks, and airtight measures are adopted to prevent the materials from dusting during transportation. After the truck enters the wood pellet factory, it directly enters the raw material stacking room in the wood pellet factory for unloading, thereby minimizing the dust pollution during the transportation and unloading of the raw materials.
Utilities	Water supply system	Supplied by the water supply network of the industrial park
	Drainage system	Using "rain and sewage diversion", rainwater is discharged into the rainwater pipe network of the industrial park, and domestic sewage is discharged into the sewage pipe network of the industrial park after collection and treatment.
	Power supply system	Supplied by the power supply system of the industrial park
Environmental protection project	Exhaust gas treatment	The raw material stacking room is a closed compartment, which is connected with the pelletizing workshop through the feeding screw auger. The dust generated by the wood sawdust biomass wood pellet mill granulator is led to the bag filter through the exhaust port on the hot selling good quality sawdust pellet mill machine, and the exhaust gas is discharged through the 1#15m high exhaust pipe.
	Noise prevention	Noise reduction measures such as sound insulation and vibration reduction
	Solid waste disposal	Set up a hazardous waste temporary storage room that meets the requirements for storing waste oil drums.

Main raw and auxiliary materials and energy consumption 

Wood pellet production process and new agricultural waste wood pellet machines

Wood pellet factory process flow

The 8 tons hr industrial straw rice husk sawdust wood pellet factory project is produced by purchasing raw materials such as sawdust, straw and rice husk that meet the requirements of direct granulation processing. The first phase of the 8tph wood pellet factory project has no crushing and drying processes.

The raw materials are stored in the wood pellet factory workshop, and the raw materials are automatically transported to the rice husk sawdust straw granulator through the feeding auger. The raw materials are compressed and molded in the rice husk sawdust straw granulator and stored in the wood pellet factory warehouse.

After the feed auger sucks in the raw materials from the raw material room, they are transported to the biomass wood pellet machine in a closed manner, and the wood pellet factory process is dust-free production. Dust mainly comes from the wood pelletizer equipment granulation process.
