Dissociating apparatus for papermaking raw material and method for dissociating papermaking raw material

摘要

A dissociating apparatus of papermaking raw material includes a rotary drum for receiving the papermaking raw material therein. The rotary drum has an engaging portion on an inner wall thereof for engaging the papermaking raw material. The dissociating apparatus also includes a rotary vane disposed inside the rotary drum for hitting the papermaking raw material falling from the engaging portion. In a method of dissociating the papermaking raw material, the raw material on the rotary drum is hit by the rotary vane to collide with the inner surface of the rotary drum, and falls on a bottom surface of the rotary drum to collide therewith. Thus, the raw material is properly dissociated.
