METHODS AND SYSTEMS FOR PRODUCTION OF HEAT RESISTANT ACCELERANT SUSPENSION AND ADDITION OF ACCELERANT SUSPENSION INTO AQUEOUS DISPERSION OF CALCINED GYPSUM AFTER MIXER Russian patent published in 2009 - IPC C04B40/00 

FIELD: construction.

SUBSTANCE: method includes introduction of heat-resistant accelerant and liquid medium into the first mixing device, their mixing to make suspension of heat-resistant accelerant. Aqueous suspension of calcined gypsum is produced in the second mixing device. Aqueous dispersion is loaded from the second mixing device into drain apparatus. Suspension of heat-resistant accelerant is brought from the first mixing device into drain apparatus. Method is realised with the help of system for production of heat-resistant accelerant, which comprises source of heat-resistant accelerant, source of liquid medium, the first mixing device, at the same time sources are functionally connected to the first mixing device, the second mixing device, besides, drain apparatus is functionally connected to outlet of the second mixing device, injection device. Moreover, the first mixing device and drain apparatus are functionally connected to injection device.

EFFECT: improved efficiency of heat-resistant accelerant.
