process of manuafacturing wood pellets

The process of manufacturing biomass pellets involves placing ground biomass under high pressure and forcing it through a round opening called a die. When exposed to the appropriate conditions, the biomass “fuses” together, forming a solid mass. This process is known as extrusion. Some biomass naturally forms high-quality fuel pellets, while other types of biomass may need additives to serve as a “binder” that holds the pellet together. However, the creation of the pellets is only a small step in the overall process of manufacturing fuel pellets. These steps involve feed stock grinding, moisture control, extrusion, cooling, and packaging. Each step must be carried out with care if the final product is to be of acceptable quality.

This series pellet maker machine can be powered by both diesel engine and e-motor. We adopt the new design of direct connection of motor shaft and the main shaft that overcome the loose defect of belt connecting as long time using. When the raw materials are added in the template by pressing roller, they will be heated to 60-80 degrees by the friction among them. After being pressed through the template, the fodder will be thrown out from the machine in a state of granule. You can choose the size of the granules by using different template with different size of holes in it.A diesel engine is another choice to drive the machine, together with the clutch and accelerating decelerating device to change its speed. the wood pellet mill is still for the belt to drive the main shaft. The feed pellet mill can run smoothly and with few noises.

how many types of pellet mill?which type is suitable for you?

There are several different designs of pellet mill. two main types are ring die and flat die type pellet mill At the beginning of the 20th century when the first pelleted feed making machine were used for feed pellet production a flat die design of pellet mill was used. The flat die design is still used in feed pellet production today, however other designs are now also common. The feed pellet machine comprises a set of rollers and die, as material enters the pellet mill it is compressed through the holes in the die to form the pellet shape. This is an extremely simplified version of the process, as in reality several factors impact on the process and the ability to produce quality pellets. 

introduction of flat die pellet mill

pellet machine is the process of making waste materials into solid fuel or feed.the raw materials can be made from any type of agro-forestry waster:groundnut shell,
sugarcane bio-gases,saw dust,coffee husk,paddy straw ,sunflower stalk,cotton stalks,tobacco waste mustard stalk,jute waste,bamboo dust,tea waste,wheat straw,palm husk,soybeans husk rice husks,wood chips and many agro wastes.the pellet machine can make these raw materials into useful fuel or feed pellet for animals.

Requirements for the raw materials:

1. size of raw materials: powder or no longer than 1cm

2. moisture content of raw materials: 18-23%

3. raw materials can be the mixture of 2 or more than 2 kinds different materials, they must be evenly mixed.

wood pellet production machinery processing grass pellets and fuel pellets

making biomass pellets has a very wide range of sources of raw materials, wood processing and man-made board production of sawdust, wood shavings, bark, sanding powder, waste wood, wood branches; After harvesting the crops to produce all kinds of straw; Other various can burn biomass can also be used as a raw material. Don't need to add any adhesive, through the processing equipment, can manufacture biomass pellet fuel.the wood pellet production machine is one new kind of gear box which is better than old model, and the pellet machine for sale is good to make wood pellets than before.the pellet maker also can make the oil cake for the feedstuff , which could be granule pellet for the fish, chicken, animal, etc.The final size is Dia 6,8,10,12mm for the sawdust pellet , and 2mm, 4mm, 6mm, 8mm, 10mm, 12mm, etc. For animals food .According to the requirements of clients, the length of the pellets can be adjusted.

Pellet Making process

Making pellets is a skilled process, it needs the right equipment and operator knowledge. To produce quality durable pellets, the material must have a certain moisture content, and the necessary binding qualities. Lignin is the natural binder contained within all biomass. However some materials during pellet production require an additional binder.
