NFLG develops and manufactures a twin spiral continuous blade mixer (also known as a double horizontal shaft mixing host) which has a high circulating flow speed and has the advantages of powerful twisting flow and cutting and shearing effects. The concrete is mixed and kneaded faster, the workability is better, and the quality of the concrete is higher. At present, NFLG has three types of mixers with double horizontal shafts: twin spiral clean shaft, reinforced hydraulics, and prefabricated parts (single outlet, double outlet) mixer.
