ABSTRACT:
An apparatus and method for degassing a mix of cement and a polymeric binding agent including filler material and/or fiber. The apparatus includes a vacuum chamber and a mechanism for adjusting the pressure inside the vacuum chamber. The vacuum chamber has an upper inlet zone including an inlet port, a lower discharge zone including a discharge port and an intermediate zone therebetween. Structure is provided adjacent to the inlet port which is open to the atmosphere for guiding the mix toward the inlet port. Structure is also positioned in the intermediate zone of the vacuum chamber for receiving, distributing and expediting the degassification of the free falling mix entering the vacuum chamber through the upper inlet port. A vacuum seal is provided by the mix entering the inlet port and by the degassed mix exiting the discharge port.
