| 摘要 |
<p>The present invention relates to hogger and reducing apparatus and considers issues associated with fibrous and other materials clogging screening apertures (407). The use of a paddle arrangement (401) having an open framework is discussed, this arrangement (401) rotating relative to the screening apertures (407) provided on a drum (40). Either or both the paddle arrangement (401) and drum (40) may rotate, the resultant action increasing agitation of raw material (being reduced in size by a reducing means) in the vicinity of the screening apertures (407) and also providing a wiping type effect to help clear material from within the apertures (407). Use of paddle arrangements in inclined and vertical type hoggers is discussed.</p> |
