Equipment introduction: 1) The kneader is an ideal equipment for mixing, kneading, crushing, dispersing and repolymerizing high-viscosity elastic-plastic materials. It has the advantages of uniform mixing and high kneading efficiency; 2) Stirring method: through two groups Stirring paddles (Z-type or ∑-type) with different speeds are strongly extruded and sheared to make the materials evenly mixed;3) The kneader can be divided into three types: vacuum type, pressure type, and normal pressure type; 4) Heating and cooling method: heat transfer oil Heating, jacket electric heating, steam heating, water cooling, etc.;5) Opening method: hydraulic opening. 6) Discharging method: hydraulic cylinder dumping, bottom discharging, screw extrusion, etc.
