摘要 |
The apparatus includes a two-stage mixer formed within a single housing and including a first high shear mixer and a second low shear mixer. Plaster slurry is formed in the first mixer. A partition is laid on a first fixing sheet, a portion laid on a second fixing sheet, and the remainder discharged to the second mixer. In the second mixer, foam is added and the formed slurry is laid on the unformed slurry on the first fixing sheet. The unformed slurry in the second fixing sheet is brought to the formed slurry to join the product.
