A conical mill (or conical screen mill) is a machine used to reduce the size of material in a uniform manner. It is an alternative to the hammermill or other forms of grinding mills.As the name implies, the conical mill varies in diameter from where the feed enters to where the product exits. The conical mill operates by having the product being fed into the mill by gravity or vacuum. A ...

The material enters the pellet mill chamber, and the ring die drives the material to rotate at a high speed. Since the gap between the ring die and the pressing roller is small, when filling the material, the friction between the high-speed rotating ring die and the material and the pressing roller drives the pressure. The rollers rotate together.

The material is frozen in a solid layer of ice. After freezing, the product is placed under vacuum by closing the drying chamber. This enables the frozen solvent in the product to vaporize without passing through the liquid phase, a process known as sublimation. Typical vacuum levels during drying are between 1 mbar and 0.01 mbar.
