Material from the mill floor is lifted by plows and the continuous flowing airstream and directed between the roller and fixed die ring where it is ground using a combination of attrition and impact. When the material is ground to the desired fineness, it is sized and discharged from the mill via air stream.
tional ball-mill systems, high-pressure grinding rolls in every kind of design types and their various combinations with ball mills and, of course, VRMs vertical roller mills. All of these systems treat the material to be ground differently, in that the actual grinding needed to achieve the desired character-istics varies from one to the other.
(1) Height of retaining ring The height of the retaining ring directly affects the stability of the material layer and the grinding efficiency of the vertical roller mill. If the height of the retaining ring is too high, this is not conducive to the overflow of the material, leading to the thickening of the material bed.
The dam ring height is the height measured from the grinding table segment to the top of the dam ring. f For vertical mills the dam ring height is often referred to as "% of table diameter". The optimum height normally being in the range 2.5 - 4% of table diameter.
Furthermore wood pellets produced by the rotating roller design are much longer, of up to 3 centimeters or more. Last but not least, roller-driven design ensures more powerful compression on the materials, so it can process hardwood materials into biomass pellets more easily than other die-driven wood pellet mills.
