How to build a 5-6 t/h biomass pelletizing plant?

Richi Machinery can according to the characteristics of each biomass material, yield size, water content, application demand, cost control, degree of automation, site conditions and other factors, for customers to design the most suitable biomass pellet production process, and configuration of efficient and safe equipment.

5-6 t/h biomass pelletizing plant
  1. Determine raw materials and land for production line. You must have land first, so you can build factories, stock up on raw materials and buy equipment. General biomass pellets plant is close to raw materials or convenient transportation place, both have is the best.
  2. Budget: plant construction funds, equipment purchase funds, early operating funds, these are to be considered. Although we are biomass pellet plant manufacturer, we still hope that customers can fully consider their own financial situation before considering the development of biomass pellet processing business. Although this industry has a good future, it still needs capital to support it.
  3. Plant construction: When designing the plant, try to reasonably plan every inch of land. This is the major of our engineers. We can reasonably plan land use for the layout of the whole plant, including the layout of functional areas and equipment of the whole plant.
  4. Purchasing equipment: Before purchasing equipment, you must first learn about the product quality of biomass pellet manufacturing plant manufacturers and compare it with similar manufacturers. Compare product performance, compare customer cases, compare production strength, compare service, compare reputation, compare equipment prices, compare all aspects you care about. . .
  5. Equipment installation: The equipment manufacturer needs to send technical personnel to the site for installation or directly arrange the installation team to enter the customer site. The second scenario is common for turnkey projects. RICHI can provide a variety of installation service modes according to customer needs, no matter what country you are in.

5-6 t/h biomass pelletizing plant process design

  1. Raw material collection: there are many raw materials of pellet machine, such as crop straw, fruit shell, tree bark, sawdust and so on. Before production, at least nearly a week (or even a month) of raw material demand should be stored enough, so as not to delay normal production. At the same time, the storage of raw materials to do a good job of safety: fire, rain.
  2. Raw material crushing: before pelleting, the requirement for raw materials is 3-5MM, so in addition to raw materials such as sawdust and rice husk, the rest of the raw materials we collected need to be crushed. According to the size of raw materials, we can choose different shredders, more details can consult RICHI technical center.
  3. Raw material drying: biomass pellet machine is very strict on the water content of raw materials, water can not be higher than 15%. If the moisture content is too high, the particles are easy to break, or even not formed.
  4. Raw material transportation: In order to save labor, we usually configure a transportation equipment. The treated raw material is sent to the feed port of the biomass granulator through the conveyor. According to the customer’s process configuration and biomass pelletizing plant situation, conveyor optional belt conveyor, scraper conveyor, bucket elevator.
  5. Raw material pelletizing: do not need me to say, you must know that biomass pellet machine is the most important equipment of the whole biomass pellet line. The RICHI MZLH series biomass pelletizer machine we usually configure for our customers is an expert in pressing poor adhesion of raw materials.

    This kind of biomass granulating equipment is very stable, pressing capacity is very strong, the production of large pellet density, high molding rate.

    Please don’t ask me about vertical granulator, you only need to know that none of the internationally renowned high-quality ring die granulator manufacturers to manufacture vertical granulator, because it is not necessary. Horizontal ring die granulator is irreplaceable.
  6. Pellet cooling: the temperature of freshly made biomass pellets is as high as 80 or 90 degrees. If bagging will cause a fire at this time, it must be cooled to room temperature by the cooling machine before bagging and storage.
  7. Pellet packaging: The cooled and complete pellets are conveyed to the packaging machine by a conveyor, and the packaging machine performs metering and bag packaging, and finally sends them to the finished product warehouse. Then it can be sold directly.

    The packaging equipment for biomass pellets can use ordinary automatic packaging machines, tens of kilograms per package; it can also use ton bag scales, one ton per package. At present, more and more customers use this packaging method, especially in Canada. , Germany, Poland, Indonesia and other countries.

Brief description of 5.5 t/h biomass pelletizing plant process flow:

  1. Raw material preparation section: raw materials of the project are transported by car for reserve in the raw material storage yard.
  2. Slicing and crushing: the wood raw materials are sent to the slicing machine and then to the crusher for crushing into raw wood chips.
  3. Drying: The crushed sawdust is transported to the dryer for drying through the belt, and the dryer uses a biomass pellet drying furnace for heating.
  4. Granulation: the husk and dried wood chips are transported into the belt to the granulation machine, and the raw materials are pressed into granule shape under high pressure.
  5. Cooling: The temperature of the pressed biomass pellets is generally 50-60℃. In the case of packaging, they need to be cooled and transported to the finished product yard for packaging after cooling by the suspension plate.

    For unqualified products can be repeated as raw materials, reprocessing, recycling. The biomass fuel after molding is small in volume, heavy in ratio, resistant to combustion and easy to store and transport.


  • The 5.5t/h biomass pelletizing plant project raw materials, auxiliary materials and finished products need to be transported into the factory from the outside, large volume. Vehicles entering and leaving the project and driving in the project every day are mainly raw material transport vehicles and finished product transport vehicles. Among them, raw materials need to be transported 4,000 times a year and finished products need to be transported 3,500 times a year.
  • The 5.5t/h biomass pellet making plant project used in the process of wood drying heat drying furnace burning biomass pellets will blow to the dryer drying way, according to the RICHI engineer calculation, the dryer every year to consume 200 tons of biomass granule.
  • The project configuration of drying furnace, every year will produce 20 tons of ashes, RICHI advising clients to set the storage yard of wind rain, after the unified collection sold to neighboring farmers for ashes farmland as inorganic fertilizer.

5.5 t/h biomass pelletizing plant layout

The general layout provided by RICHI engineers has made the functional zoning clear, with production area and office area set up. Combined with the characteristics of customer production, we organize the flow routes of raw materials, finished products and production personnel respectively, so as to achieve the requirements of distribution and convenient management.

We placed the production area in the south of the factory, and the auxiliary buildings and office buildings in the north. This can meet the production and use requirements and the reasonable layout of the production line, convenient transportation.

We set the entrance and exit of raw materials and finished products in the west of the factory. From the perspective of streamline organization, the flow of people and logistics are distinct and basically do not cross each other, which is conducive to enterprise management and the safety of enterprise employees.

According to the completion of the final project, from the perspective of environmental protection, Engineer RICH suggested that the customer strengthen the planning of plant greening, increase the greening rate of the factory, carry out turf greening and planting trees on the existing open space, ensure the green area, so as to improve the plant environment and beautify the plant.
