Uniform mixing no precipitation colloidal grout mixing machine is mainly used for wet eddy current dispersion and mixing of water, cement and other powders. Eddy current is a vortex-type water whirlpool, which is formed by the activity of anti-water current. The object in the fluid, along the section perpendicular to the velocity, has the pressure difference generated by the fluid flow to form a vortex, also called eddy current.
