Mixing shafts The mixing shaft made from smithing alloy steel. They have the best torsion-bent intension. Drive device Drive device droved by two-planetary gear boxes. And this kind of design has advantages of compact configuration, stabilized driving, low noise and long used life. Shaft sealing The mixing shaft have long life because they are sealed by two reliable face seals and the others unique seal which combinate high pressure grease. Automatic grease lubrication Distributor will distribute grease come from grease pump to all lubricated points. High grease pressure, bigger viscosity and smaller grease consumption these can decrease the grease consumption these can decrease the grease stain to concrete. Mixing device Thanks for the mixing arms are streamline both inaxial and in radial, the material in trough not only is cut in radial but also is pushed in axial, so that it is mixed more turbulent and can reach the homogeneity in short time. For the unique design to mixing system it can save cement. Hydraulic discharging device Hydraulic discharge can avoid some disadvantages with pneumatic discharging device like not opening the discharging door because of low air pressure. When the discharging door in the half opened, we can set the opening door device at a random angle. And if it is in emergency, we can open the discharging door by pressing the manual-discharging knob.
