How to Select Your Pellet Mill?

The Types of The Pellet Mill

There are a variety of pellet mill designs and types that boast distinct features, each with its own operating principle. The two leading models are the flat die pellet mill and ring die pellet mill. Understanding their differences is key to making an informed decision when selecting your ideal model for production purposes.

Flat Die Pellet Mill


With a straightforward setup and extensive range of applications, the flat die pellet mill is an invaluable machine. It can process almost any biomass material without adding extra ingredients or additives, such as hardwood, pinewood, peanut shells and more! Thanks to the self-regulating mechanism of the pressing wheel, materials are evenly distributed and stabilized during molding; thus ensuring a consistent production.

Working principle

Upon the material’s arrival to the flat die surface, multiple holes are visible. As soon as the roller starts running, that material is now being pressed into those holes on the die. Once compressed and in cylindrical form, these objects eventually come out from beneath of each hole – only then does a cutter step in and cut them down into pellets!

Ring Die Pellet Mill


The ring die pellet mill is notably efficient and energy-saving, thanks to its identical speeds of the roller line and ring die. All pressure generated during operation is utilized solely for making pellets, optimizing the process while ensuring maximum efficiency. By eliminating additional friction from other components, this type of pellet mill provides a high output with minimal power consumption.

Working Principle

The ring die pellet mill contains two to four rollers and a driven roller, the latter enclosing a cylinder with numerous holes. When material is fed into this chamber, the rollers compress it against the walls of these tiny openings. The pressure then forces them out through small spaces in the cylinder where they are ultimately cut into cylindrical pellets by an integrated cutter.

Type. Now, we know the main types of the pellet mill, they are ring die pellet mill and flat die pellet mill. The ring die pellet mill provides excellent efficiency, resulting in a finished pellet with remarkable hardness. Despite its complex manufacturing process, ring die pellet mills are more costly than their flat die counterparts. In contrast to its counterpart, the flat pellet mill is structurally uncomplicated and easy to maintain; however, it produces lower output than a ring die pellet mill. In comparison, the flat die pellet mill is perfect for small-scale production, while the ring die pellet mill offers an ideal solution for larger and middle-sized plants.

Appearance quality. The spray lacquer on the surface of the pellet mill must be even and durable, with zero paint leakage. The stainless steel component must be polished to a smooth finish, with no scratches or abrasions.

Flat die pellet mill should mainly check the cutter’s quality, and the ring die pellet mill should check the roller bracket and the roller’s fastening situation.

It is important to choose the right machine for your pellet mill project. Each machine has its own pros and cons, so you must have a detailed understanding of what you’re looking for and what works best in your material and application. When considering a pellet mill project, it’s important to compare technical specs between various machines as well as their fee structure and warranty.
