Embodiment Construction

[0027] Directions Instructions:

[0028] The pins installed on the rotor disc 8 and the stator disc 7 (including the rotor pin 6 and the stator pin 5) and other parts are inward in the direction close to the axis of the rotor disc 8 or stator disc 7, and outward in the opposite direction; The tangential direction of the shaped rotor disc 8 or the stator disc 7 is tangential, Figure 4 The direction indicated by the middle arc arrow is the rotation direction of the rotor disk 8 .

[0029] Structure description:

[0030] Such as figure 1 as well as Figure 2 to Figure 4 As shown, the pulverizer with impact crushing and extrusion shearing crushing functions of the present invention includes a motor 10, a casing 4, a rotor component and a stator component. The casing 4 is a disc-shaped shell with high sides on the periphery. The casing 4 is provided with a rectangular discharge port 1 along the tangential direction. The lower end surface of the casing 4 is fixedly connected wi...

Abstract

The invention discloses a crusher with functions of impact crushing and extrusion shearing crushing. The crusher comprises a motor, a housing, a rotor assembly and a stator assembly, wherein the rotor assembly comprises a rotor disc and a rotor pin, the stator assembly comprises a stator disc and a stator pin, the rotor pin and the stator pin comprise quadrangular prism-shaped steel billets, the front portions of tangential direction work surfaces of the rotor pin and the stator pin are standard zigzag surfaces, the end of the tangential direction work surface is provided with a first special-shaped zigzag, a width of the top portion of the first special-shaped zigzag is at least two times the width of the tooth bottom of an ordinary zigzag on the front portion of the tangential direction work surface, and an included angle formed by the tangential direction work surface of the stator pin / the rotor pin and a tangent surface of the prism surface A passing through the axis line of the stator pin / the rotor pin is more than or equal to 5 DEG and is less than or equal to 20 DEG. The crusher has characteristics of simple structure, high crushing rate, high crushing efficiency, low cost, small size, wide application range, simple operation, good sealing, less wearing parts, low auxiliary material consumption, high efficiency, and energy saving.

Description

technical field [0001] The invention relates to a pulverizer with the functions of impact pulverization and extrusion shear pulverization. The pulverizer is used in grain processing, feed processing, metallurgy, chemical engineering, plastics, medicine, construction, electronics, energy and many other fields Various brittle or plastic solid materials of particle size are crushed into fine particles. Background technique [0002] The wheat flour milling industry at home and abroad widely uses a crushing machine called impact mill. The impact mill consists of a casing, a rotor part, a stator part and a motor. Wherein the rotor component includes a hub, a disc-shaped rotor disc fixed on the hub, and at least 3 turns on the rotor disc, with dozens of rotor pins per turn. The stator part includes a cover plate, a stator plate fixed on the cover plate, and at least 3 circles and dozens of stator pins per circle installed on the stator plate. The existing impact mill mainly reli...
