The selection of the right wood pellet equipment and technology for a wood pellet processing equipment system is critical when establish your own biomass fure wood pellet manufacturing business.

Next, I will list two wood pellet production plant projects we have done for you, hoping to help you.

Case 1: 4 t/h Wood Pellets Plant project

This project mainly uses wood scraps from the wood carving industry and delumber factories as raw materials to process and produce biomass molding fuels, such as wood residues (referring to wood cutoffs, corner waste, etc.) and processing residues (referring to boards, slats, wood and bamboo cuts, sawdust, broken veneer, wood core, shavings, wood blocks and leftovers, etc.).

After the biomass is chipped, crushed and extruded, its volume is greatly reduced, which makes it easier to transport, store and use.

It is suitable for biomass power generation, clean energy transformation of industrial boilers, new cooking fuels in rural areas, and makes full use of the woodcarving industry and solutions. Timber waste and leftovers in wood mills, processing residues, etc.

4T/H wood pellet processing equipment system Production Process

Biomass pellet fuel is a new type of clean fuel that uses wood and straw agricultural solid waste as raw materials and undergoes crushing, crushing, transmission, extrusion molding, packaging and other processes to make briquettes such as blocks and granules, which can be directly burned.

  1. Raw materials are transported by vehicles into the raw material yard for storage.
  2. Chipping of raw materials: Use trolleys and other tools to transport raw materials to the production workshop, and put large pieces of wood raw materials into crushers for chipping and crushing.
  3. Crushing of raw materials: Broken raw materials such as sawdust, wood blocks and crushed materials can be directly put into the crusher for crushing. Dust and noise will be generated during the crushing process. The dust is processed by cyclone sorting + bag filter, and the processed The dust is reused in production.
  4. Powder transmission: After the raw material is crushed, the powder falls into the silo and then is transported to the granulator by the feeding auger through the unloader.

    During this process, except for the unsealed connection of the equipment, other places are closed devices. Cloth bags are used to seal the airtight place to intercept the dust that may be generated, so basically no dust will be discharged.
  5. Extrusion (granulation): The powder is extruded in a wood pelletizer machine.
  6. Packaging: The granulated products are put into packaging bags through the finished product silo of the wood granulator.
  7. Stacking of finished products: After the finished products are packaged, they are uniformly stacked in the finished product stacking room.

General layout

The 4t/h wood pellet processing equipment project leases the existing factory building for decoration and reconstruction according to the project design. The area is divided into raw material areas, finished product storage areas and production workshops.

The project land is irregular rectangle. The open-air raw material storage yard is arranged in the northeast of the project factory area, which is used to stack some wood raw materials.

The production workshop is located in the north of the middle area of the factory area. The production workshop is equipped with production equipment for raw material crushing, transmission, compression molding, packaging and other processes.

The finished product stacking room is connected to it on the west side of production workshop, and the raw material plant stacking room is located on the south side of the production workshop and is connected to the production workshop.

Office and rest rooms are located in the west of the factory area, adjacent to the finished product stacking room. The domestic wastewater is treated in the septic tank and then discharged into the temporary wastewater storage tank located in the southeast corner of the plant area.

The plant area and its surroundings are well greened. Lubricating oil is required for the operation, maintenance and maintenance of machinery and equipment in this project, and a small amount of waste lubricating oil will be generated. A hazardous waste temporary storage room is set up for the storage of waste lubricating oil, which has little impact on the environment.

Generally speaking, the construction of the project factory area meets the technological process of biomass pellet fuel processing, and also meets the requirements of raw materials, finished products, water, electricity, roads and other aspects. , the overall layout of the project is very reasonable.

4T/H wood pellet processing equipment Process Design

The project puts the recovered wood into the funnel through the wood grabber, and transports it to the pulverizer through the conveyor belt for pulverization (the particle size after pulverization is less than 5mm). The granulator compresses the wood powder into granules with a compression ratio of 5.5:1, and then after natural drying, it can be packaged and shipped.

The raw material of the project is the leftover material of the furniture factory, and the moisture content of the wood is about 8%-15%, which meets the requirements of granulation and molding, so there is no need to dry during the wood pellet production process.
