We are all aware that there are many distinct designs and types of pellet mills and that each type of wood pellet mill machine for industry has a unique set of features and a distinct method of operation. The ring die and the flat die pellet mill is the two primary categories of pellet mills.
The Flat Die Pellet Mill
The flat die pellet mill has a straightforward design and a broad processing range, allowing it to process a wide variety of biomass raw materials without the need for any additives. These materials include hardwood, peanut shells, pinewood, and any other biomass raw material that can be found. Because the pressing wheel has an automatic regulating function, the material will not be crowded, which will keep the molding stable. This is one of the benefits of having this function.
It begins to move as soon as a material reaches the flat die. In the end, the material will be compressed into a cylindrical object and emerge from the holes at the bottom. By using a cutter, the cylindrical object will be reduced to pellets.
The Ring Die Pellet Mill
This type of pellet mill has high efficiency and low power consumption is the most notable characteristics of this type of machine. There is no additional friction, and the ring die and the entire line of the roller are moving at the same speed. Since the rind die pellet mill puts every bit of available pressure toward producing pellets, it is by far the most efficient of the two types.
It has two to four rollers and a driven roller. Additionally, the ring die is a cylinder pierced with many holes. When the material is introduced into the ring die pellet mill's working area, the rollers within the cylinder will press the material into the holes. Following this step, the material will be squeezed out of the cylinder, and the cutter will cut them into the cylindrical pellet.
How to Choose the Best Pellet Mill For Your Needs
You have to consider the vital features of a pellet mill before you decide. Some of which are discussed below:
Type
Flat die and ring die pellet mills are the two main types. High-efficiency ring die pellet mills produce tough pellets. Because it is more complicated to make and they cost more. Flat pellet mills are simple and easy to store, but their efficiency is lower than ring die mills. Ring die pellet mills are best for large and medium-sized plants, while flat die pellet mills are best for small plants.
Quality of Appearance
There should be no paint leakage, and the spray lacquer on the surface of the pellet mill should have a balanced and stable appearance. The component made out of stainless steel ought to have a smooth surface that is unblemished by any knocks or scratches.
Quality of the Cutter
The quality of the cutter is an essential thing that needs to be checked on a flat die pellet mill. A ring die pellet mill needs to check the roller bracket and the roller's fastening situation.
Check How Secured It Is
The ring die pellet mill's main shaft has a safety linkage device to prevent foreign objects from damaging it. Foreign matter in the ring die increases the main shaft's resistance, causing the safety cock to fail. The convex side of the clutch then contacts a limit switch shafting fork, cutting power to the main shaft motor. This prevents pellet mill damage. To choose the best ring die pellet mill for your needs, determine if the clutch's convex side can contact the limit switch's shafting fork. Don't buy what you can't get.
End Thoughts
Make sure you choose the right pellet mill so you will get the quality of pellets you need to produce the required energy. Keep in mind the above factors when deciding. If you think you cannot decide well, you can always ask an expert’s advice.
