s2: the material is driven by high-speed airflow of 150-250 m/s, the vortex is rotated and moved at a high speed, the material is dried and crushed in the rotating and moving process, the water content of the material is reduced by 10-15%, the part of the material with the granularity of 30-3 mm accounts for 15%, the part of the material with the granularity of 50-30 meshes accounts for 45-55%, the part below 50 meshes accounts for more than 30-40%, and the total amount is 100%;
s3: the materials enter a discharging system after being dried and crushed.
10. A method of dry pulverizing in a vortex dry pulverizer as defined in claim 9, wherein: and (3) repeatedly putting the materials obtained in the step (S3) into a feed pipe, repeating the steps (S1) - (S3), and drying and crushing again until the granularity and the water content of the materials obtained in the step (S3) reach expected values.
