FIELD: construction industry.
SUBSTANCE: invention refers to construction industry, and namely to gypsum treatment devices and methods. Invention will allow preventing hot exhaust gas loss. Mixer used for gypsum treatment device consists of a housing having an upper wall, lower wall, and at least one side wall. Housing can be manufactured and made with the possibility of receiving and treating gypsum-based product. Mixer's frame the shape of the cross section whereof is similar to the housing cross section is located near the housing lower wall. Mixer's frame is connected inside the housing with the possibility of swaying therewith for back-and-forth motion between the first and second positions.
EFFECT: mixer is made with the possibility of preventing local through fluid medium passes, for providing fluidisation of gypsum products, and preventing accumulation thereof near the housing lower wall.
