Process for making biomass pellets from wet materials

Production process analysis of biomass pellets with drying

Process flow:

The wet wood powder enters the drum dryer through the belt conveyor for drying;
The dried wood powder enters the pellet mill through the conveyor belt;
The high temperature particles enter the cooler for cooling through the conveyor belt;
The cooled pellets enter the packaging machine for packaging.

Technological advantages: The cost of raw materials is relatively low, the particle forming effect is good, and the profit margin is relatively large.

Process disadvantages: Subject to the shortage of raw materials, it is difficult to increase production capacity.

Note: Wet sawdust with more than 20% moisture must be dried with a dryer. Recommended users: large wood processing plants, garden companies and other users with raw material advantages.

How to choose the correct manufacturer of pellet equipment

Look for raw materials that can be directly made into pellets, such as dry sawdust, rice husks, peanut shells, mushroom residues, bagasse and other biomass powders;
After the raw materials are determined, it is necessary to determine the workshop. The construction or search of the workshop is generally close to the raw materials or a place with convenient transportation. It is the best to have both.
Transformers, the biomass granulation industry consumes a lot of electricity. After determining the production capacity, choose the transformer that matches the production capacity according to the equipment power provided by the equipment manufacturer.
Before purchasing equipment, you must first understand the product quality of the equipment manufacturer. It is often difficult to distinguish the quality of the product in the network environment. You must visit the manufacturer on the spot, and don’t be fooled by the low price. The centrifugal high-efficiency pellet machine is the invention patent of our company, and it has now been upgraded to the 8th generation. The strong technical strength of Yulong Machinery will escort your pellets.

Biomass pellet production line equipment composition

Drum dryer

The cylinder is not only welded with the lifting plate, but also has a blade shaft. The advantage of the blade shaft is to increase the number of material turnovers, increase the contact surface with the wet material, and improve the drying efficiency.

8th generation centrifugal high-efficiency pellet machine

The 8th generation centrifugal high-efficiency pellet mill is our patented product. There are 560 models with a power of 132KW and an hourly output of 1.5-2 tons, and 850 models with a power of 250KW and a production capacity of 3-4. You can choose the device model according to your needs.

Belt conveyors

The belt conveyor has the advantages of strong conveying capacity, long conveying distance, simple structure and easy maintenance, and can easily implement programmed control and automatic operation.

Rectangular warehouse

The material used is thick galvanized sheet, which has high density, is not easy to deform and corrode, and has a long service life. The modular structure is used for installation, which is convenient for transportation and on-site assembly by customers; the bottom of the warehouse is equipped with a hydraulic screed device to prevent materials from bridging; the bottom is equipped with a screw conveyor and frequency conversion feeding to ensure stable feeding of the pellet machine.

Cooler

The unique vibrating mechanism is used to discharge material, which has stable operation and smooth discharge. Using the principle of counter-flow cooling, the particles are fully and uniformly cooled.

Packing Machine

Customers can choose the type of packaging scale according to their own requirements; of course, in the complete production line, they can choose the combination of large and small packaging scales.

Note: This is a set of conventional simple biomass pellet production line, we can customize different pellet production solutions for you according to different sites, raw materials, output and budget. As a leading pellet machine manufacturer in China, Yulong Machinery has rich experience and can build a unique small pellet factory for you according to the actual situation.
