Abstract
To provide a mill that can greatly reduce noise during operation and can also contribute to greater device compactness. The mill is provided with: a tubular drum body configured in a manner so that a material to be milled introduced from one section can be discharged from another section; a central shaft that penetrates within the drum body in the direction of tube length thereof; and a plurality of milling plates that are attached at a predetermined interval in the axial direction of the central shaft, and that compartmentalize the interior space of the drum body in to a plurality of milling chambers. The drum body and/or the milling plates rotate, and the mill does not have a milling medium that mills the material to be milled by contacting the material to be milled while rolling within the drum body.
Claims10
A mill comprising
- a cylindrical drum body configured so that material to be milled is taken in through a hopper for the mill and milled material is discharged from a drum outlet,
- a central rotating shaft penetrating said drum body in a longitudinal direction,
- a plurality of milling plates that are attached to the central rotating shaft with predetermined spacing in the longitudinal direction of said central rotating shaft, and divide interior space of said drum body into a plurality of milling chambers,
- and wherein the mill does not comprise a milling media which mills material by contacting said materials therewith while moving by rolling in said drum body,
- a plurality of pressure receiving members, each pressure receiving member being attached to the drum body, located in a respective milling chamber and facing each of the milling plates defining the respective milling chamber, wherein each pressure receiving member having a plurality of holes that allow for the passage of material being milled;
- wherein the milling plates are inclined with respect to a plane intersecting the central rotating shaft at a right angle, and further wherein the rotating milling plates mill the material against the pressure receiving members in the milling chambers, and move the material sequentially through the pressure receiving members from the hopper to the drum outlet.
