Pellet mills or machines are used in making either biomass or wood pellets. Research on how to make wood pellets is rapidly growing and information about various types of pellet mills is required to produce pellets.
It is vital in either case, to fully understand the basics of pellet mills before making any purchase arrangements. The following details are aimed at help you make an informed decision before you purchase a pellet mill. Keeping in mind that the most important piece of equipment you'll need to make pellets is the pellet machine, therefore familiarize yourself with how they operate.
When you begin researching the pellet making process, you will realize that there are only two different types of pellet mills that are used to make pellets. The operational difference between these two types of machines comes down to the type of die that they use to form the pellets. These two types are known as the flat plate type pellet mil and ring die type pellet mill.
The first is the ring die type pellet mill which as the name suggests uses a ring die to form the pellets. The ring die is a thick metal cylinder with holes drilled through the cylinder around the circumference. The machine is designed such that inside the ring there are rollers that are used to push the material through the die. Wood wastes which are the major raw materials are fed into the center of the ring, and the rollers force them through the holes of the ring die. The formed pellets then emerge from the outside of the die.
This type of machine is what you would come across in a commercial pellet plant that produces a high volume of pellets. The ring die type mill is very costly due to heavy duty machine that is largely out of the price range for most people who make their own biomass or wood pellets.
The second type is the flat plate die type pellet mill. This machine utilizes a flat plate to form the pellets. It works similarly as the meat grinder, the die used in the meat grinder is very similar to that of the flat plate style pellet mill. The die is made from a thick round flat plate with many holes drilled through it. A set of rollers ride on top of the plate, and when the raw feed stock is fed into the machine, the die turns along with the rollers.
To get a better scenario of how this arrangement works is to imagine how a wheel on the edge of record player works. The combination of the die and roller action forces the raw material through the die causing the formed pellets to exit on the underside of the die, where they fall into a chute and then exit the machine. The flat plate type pellet mill is typically cheaper than the ring die pellet mill, and is mostly used by small scale pellet producers.
They are also relatively simple to work on, and can be powered using various methods. By utilizing a power source that you may already own, you can save a lot of money by buying only the mill portion. Pellet mills or machines are used in making either biomass or wood pellets.
