The invention designs a high-speed vortex pulverizer. The high-speed vortex pulverizer comprises a screw, a felt ring oil seal, a bearing end cover, a deep groove ball bearing, a blade, a shaft sleeve, a box body, a positioning screw, a water cooling water pipe, a feeding hopper, a large belt wheel, a motor, a motor supporting frame, foundation bolts, a main shaft, a partition plate, hard rubber,a spiral conveying blade, a pin hole, a primary crushing chamber, a secondary crushing chamber, a dovetail groove, a small belt wheel, a conveying belt, a key, a cross clamping groove and a knife rest. A crushing chamber is divided into two parts, namely the primary crushing chamber and the secondary crushing chamber, the primary crushing chamber is used for completing the coarse crushing process,and the secondary crushing chamber is used for completing the fine crushing process so that materials can be uniformly crushed, particle sizes of discharged powder materials are consistent, the machine vibration, the heat productivity and the knife abrasion loss are reduced, and then the service life of the blade is prolonged.
