The foaming machine first appeared in foreign countries, and its original model used the high-speed rotation of the impeller to make foam, so it was also called “foaming machine”. Later, with the continuous advancement of technology, the technical content of foaming machines continued to increase, and new models continued to emerge, forming different technical systems. Foaming machines began to be used in my country as early as the 1950s, but they were not special foam machines, but mortar mixers.
That is to say, the foaming agent is directly added to the mortar mixer or concrete mixer, and the foaming machine and the mortar or concrete are stirred together to form foam. Later, around the 1970s, a special foaming machine, the high-speed impeller foaming machine, began to appear.
