Rapidflow setting plaster by Ezi-Rapid Solutions 
Prompted by this need and the lack of readily available commercial plasters of an acceptable quality, Rapid Building Systems, designed, developed and built its first Rapidflow calcination plant in Kilmore Victoria in 2002. This plant is now producing over 10 tonnes per hour of commercial grade high-strength Rapidflow setting plaster. Testing indicates that this facility now produces product that is amongst the highest quality and most consistent plaster available in the world today. It is generally accepted that beta plasters produced by conventional means (kettles, rotary kilns and the like) provide only relatively low strength plasters with high water take-up during setting. This is not the case with plaster produced from the Rapidflow Calciner. The Rapidflow Calciner is based on the fluidised bed concept that differs significantly from other fluidised bed calciner designs. It uses a unique process that allows the introduction of hot gases into the fluidised bed in a completely controlled manner.
