摘要： An apparatus (100) for the production of a plaster slurry is described, the apparatus (100) comprising a mixer (102) for mixing at least plaster and water to form a plaster slurry, the mixer (102) comprising an outlet conduit (122), a foam generator (106) for mixing at least air, a foaming agent and water to produce a foam, the foam generator (106) in fluid communication with the mixer (102) via a fluid pathway (116) comprising a foam conduit (117); and a mass flow meter (124), wherein the mass flow meter (124) is configured to measure the density and mass flow rate of the foam within the foam conduit (117) or the plaster slurry within the outlet conduit (122). Additionally, a method of manufacturing a plaster slurry is described.
