Title:
SAME-CAVITY INTEGRATED VERTICAL WALNUT SHELL HIGH-SPEED MULTI-STAGE SUPERFINE GRINDING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2021/208164
Kind Code:
A1
Abstract:
A same-cavity integrated vertical walnut shell high-speed multi-stage superfine grinding device, comprising a double-channel sliding type feeding device (I) and a same-cavity integrated vertical grinding device (III). The same-cavity integrated vertical grinding device comprises a lifting plate (III10) and a same-cavity integrated vertical crushing cylinder (III05). A first-stage coarse crushing area (A), a second-stage fine crushing area (B), a third-stage pneumatic impact micro-crushing area (C), and a fourth-stage jet mill superfine crushing area (D) are arranged in the same-cavity integrated vertical crushing cylinder. Walnut shells falling through the double-channel sliding type feeding device are evenly lifted into a wedge-shaped gap of the first-stage coarse crushing area by means of the lifting plate to be coarsely crushed, the second-stage fine crushing area achieves fine crushing on the coarsely crushed materials by means of a two-stage wedge-straight-through gradually-shrinking gap, the third-stage pneumatic impact micro-crushing area impacts the fine crushed particles of walnut shells at a high speed, the fine crushed particles of walnut shells are impacted and violently rubbed under carrying of high-speed airflow to be crushed, in the four-stage jet mill superfine grinding area, micro-particle grading is achieved by means of arc-shaped blades (III28), and micro-particles meeting the particle size conditions are suctioned out using negative pressure attraction.
