Pellet mil dies importance for pellet mills

The die in the pellet mill is the most important component of the process. The die effects pellet quality, productivity, energy consumption, production efficiency and reliability. The die is what forms the raw material into the pellet shape. The die contains a series of holes across its surface. As the material enters the pellet mill, it is compressed between the die surface and roller, with some material being compressed through the holes. The action of compression between roller and die, generates heat and pressure. These two forces are essential in the pellet formation process to produce quality pellets.

The size and diameter of the holes in the die vary on the market for the pellets. For example pellet stoves generally require a pellet with a diameter of 6mm, where pellet boilers can mostly handle 8mm in diameter, and in some cases even larger. Up to a certain point the diameter would change the description from a pellet to a briquette. It is harder however to design hopper and auger feed systems for briquettes.

We adopt stainless steel as the material of pellet mill dies-ring die.Our  pellet mill ring dies are machined to exacting tolerances, then drilled by computer controlled state-of-the-art gundrills. This drilling process produces an ultra smooth, mirror-like hole ensuring good pellet quality and a trouble free start-up. Special heat treating technology ensure hardness and long life.
