Original rotor structure,high mixing homogeneity. No residues: Adjustable gap between the paddles and the casing of mixing chamber ensures a very low residual ratio,effectively preventing the product from cross contamination;and the bottom discharging gate fully coinciding with the length of mixing chamber ensures the complete discharging of mixed materials in a short time,and the minimizing of residue. Suitable for mixing premix,poultry and livestock feeds,aquafeeds,feed additives and the powdery materials in food,chemical and pharmaceutical industries.
