A kind of high-speed kneader for producing PP automobile modified material, it is related to the technical field of kneader, solve the problem that the structure of
paddle is single in prior art, it is difficult to consider high-strength shearing and gentle mixing.The mixing cavity is connected with the
discharge cavity at the bottom end, and the
discharge cavity is provided with a
discharge channel at the lower end;The top of the mixing cavity is connected with an
electrical control box, and the top of the mixing cavity is also provided with a driving motor, a rotating shaft is coaxially connected in the mixing cavity, a combination stirring blade is fixed on the periphery of the rotating shaft, the combination stirring blade includes shear blade, conveying blade and cleaning blade, the shear blade, conveying blade and cleaning blade are arranged in order from top to bottom.The beneficial effect is: multiple functions can be realized by combination stirring blade, high-strength local shearing is provided, mixing is uniform, and mixing efficiency is high.
