Abstract (en)
[origin: US6425950B1] The invention relates to a method for producing foaming substances, especially foaming cement substances, consisting essentially of a starting product, especially cement paste, and a foaming agent. The inventive substances are produced in a mixing reactor which is connected to a supply container for the starting product by a feed pump. A product flow taken from the mixing reactor is conveyed to the supply container in a circuit, the foaming agent and atmospheric air being added and the supply container being kept at a minimum level. After a mixing phase, a sub-flow is taken from the product flow for processing.
