QAFS single shaft high speed disperser are applied to dissolution, mixing and dispersion of materials used in the industries such as paint, ink, dyes, pigment, medical, papermaking , etc. The Equipment can process different kinds of viscosity and capacity of coatings. It is characterized by: Absorbing very little air during mixing and dispersing, perfect solid-liquid mixing and dispersion effect, fast dissolution and fine particles during high and medium speed dispersion process. Rotational speed can be regulated as Electromagnetic Speed, Frequency Speed, Two or Three Speed.
