Method and apparatus for separating adhered paper from paper covered gypsum board. |
摘要 |
<p>Adhered paper is separated from paper covered gypsum board by hammermilling the gypsum board through a hammermill grate (18) formed by holes (20) in a semi-cylindrical casing (16), the hole size being selected to produce a screenable mixture of pieces of paper and separated gypsum board particles. The mixture may then be screened to segregate the pieces of paper from the particles.</p> |
