FIELD: method and equipment for manufacturing gypsum plates.
SUBSTANCE: method involves the following steps: first step includes molding plate; second step includes hardening by hydration process until hydrated article is produced with hydration extent within the range from 33% to 80%; third step includes continuing hydration process in at least one rotating drum by rotating plate around central axis; fourth step includes drying process. Intermediate cutting process may be provided between second and third steps, said cutting process may be effectuated in accordance with wire principle. Apparatus has linear zone for partial hardening and hydration, and at least one hydration drum comprising central axis around which multiplicity of branches are arranged. Each branch in drum may be divided into multiplicity of levers, with surface of said levers making from about 50% to about 99% the surface of respective branch. Drum may have from 10 to 150 branches, preferably from 40 to 120 branches. Hardening and hydration zone and drum may be arranged in two axes extending in parallel with one another.
EFFECT: improved quality of articles, improved maintenance and operating conditions.
