摘要

FIELD: production of formed gypsum plaster board including formed core and nonfoamed external layers. SUBSTANCE: device for production of multilayer plaster board includes two-stage mixer which has first mixer with high shearing force and rotary mixer. Part 38 is laid on the first fixing sheet material 32. Part 40 is placed on the second fixing sheet material 36, and the rest is fed to the second mixer. In the second mixer, foamed material is added and prepared slime is placed on nonfoamed slime on the first fixing sheet. Nonfoamed slime on the second fixing sheet material is transferred onto foamed slime to produce finished product. EFFECT: higher efficiency. 1 dwg
