The application discloses a vertical dry grinding device and a control method thereof, and belongs to the technical field of powder dry grinding. The device adopts a vertical single-cylinder structure, and the cylinder is sequentially divided into a first grinding zone, a second grinding zone and a grading discharge zone from bottom to top. The first grinding zone realizes mechanical coarse grinding by driving grinding medium through a rotor, the second grinding zone realizes superfine crushing of powder by high-pressure airflow, the grading discharge zone realizes separation of coarse powder and fine powder by a grading wheel, qualified fine powder is directly discharged, and unqualified coarse powder falls back for regrinding. The application integrates mechanical grinding, airflow crushing and grading into a single vertical device, reduces the equipment floor space, and improves grinding efficiency. Meanwhile, the multi-path air inlet structure reduces the powder adsorption and agglomeration, and improves the qualified rate of finished products.
