Biomass pellet machine problem highlights

What are wood pellets?

Wood pellets are renewable, clean-burning and cost stable fuel generally made from compacted sawdust or other forestry, agro wastes for heating aim both for homeowners and industrial production.

How are wood pellets produced?

Wood pellets are simply a highly compressed form of the original raw materials. Final pellet compression takes place in the pellet mill, however, there are several processes required initially before the raw material is suitable for the pellet mill. Particle size and moisture content are two crucial aspects that must be controlled before the raw material can enter the pellet mill.

Wood pellets

What are wood pellets used for?

Wood pellets are mainly used for heating purpose both for homeowners in wood pellet stove & heating furnace, and commercial production in industrial boilers, hot water boilers, biomass power plant, etc.

What size of wood pellets do your pellet mill produce?

The length and diameter of the wood pellets vary according to the size of the die in the pellet mill. Our machine can be adjusted according to you demands.

What kinds of raw materials can be used for making wood pellets?

Various forestry and agro-waste materials can be used to make wood pellets, such as wood sawdust, wood shavings, wood chips, wood logs, straw, rice husk, coffee husk, bamboo, tea waste, wheat straw, etc. The raw material is renewable and sustainable. They are available locally, so the cost is affordable and predictable.

A complete wood pellet plant

What are the main processes of a complete wood pellet plant ?

A complete wood pellet plant include crushing, drying, pelletizing, cooling and screening, weighing and packing.

What is the requirement of wood pellets moisture content after cooling?

Generally, the requirement of moisture content after cooling is 12%-15%, and not more than 18%.

What equipment is needed for wood pellet production line

Do all wood pellets and biomass pellets burn the same?

The simple answer is no, each raw material has its own combustion characteristics. These characteristics range from changes in ash content to possible clinker and slag formations and corrosion risks due to sculpture and chloride content. Different makes and designs of pellet stoves and boilers are produced to handle different levels of ash and corrosion risk. Wood pellets generate the lowest ash content, and also have the lowest corrosion risk for the stove or boiler. Other biomass fuel pellets such as straw and grass pellets can generate higher levels of ash, and pose a higher corrosion risk to the pellet combustion chamber. Grass and straw pellets however are much cheaper to produce, so much lower fuel costs are possible.

Can I adjust the pressure of the wood pellet mill to pelletize different materials?

Yes, there are screws on the pellet mill that adjust to vary the compression ratio for different materials to make wood pellets.

How long will the pellet die and rollers last?

The answer depends on how often you use the Pellet Mill and what kind of biomass you pelletize. Constant use of 4 to 8 hours a day over a period of 6 months using sawdust will wear down the die and rollers and they may need to be replaced. Less use of course and softer biomasses like grasses, leaves, and paper goods, could mean the die and rollers last well over a year. Changing to sealed bearings in the rollers is a good idea.
