s1: firstly, a driving motor (2), an air conveying motor (11) and a vibrating motor (34) are started, the driving motor (2) drives a bentonite material crushing device (1) through a driving belt (13), a motor driving turntable (14) and a crushing device driving turntable (12), a bentonite raw material is added into the bentonite material crushing device (1) through a raw material feed hopper (10), a spiral crushing cutter (21) is driven to rotate through a propelling rotating shaft (20) rotating inside the bentonite material crushing device, the spiral crushing cutter (21) initially crushes large bentonite blocks and drives the raw material to propel towards the direction of a crushing reamer (22), the initially crushed bentonite raw material enters a crushing gap between the crushing reamer (22) and a barrel wall reamer (19), and the raw material is crushed through impact and shearing force between the crushing reamer (22) and the barrel wall reamer (19) to form bentonite powder, the crushed bentonite powder with the diameter meeting the requirement enters an air-assisted purification system, and the heavy and hard impurities fall to the bottom of the inner cavity of the shell (17) of the crushing device along the crushing gap and are discharged through an impurity discharge opening (25) to realize primary purification;
s2: an air supply motor (11) drives air supply blades in an air supply discharge cover (15) to rotate to generate negative pressure suction, bentonite powder is sucked into the air supply discharge cover (15) from a crushing gap and an air supply discharge port and is blown to a cyclone separator (5) through a cyclone purification feed pipe (4), the cyclone purification feed pipe (4) is connected from a tangent point of the side surface of a barrel of the cyclone separator (5), spiral cyclone can be formed inside the cyclone separator (5), purified montmorillonite powder can be blown out from a purification discharge pipe (6) along with ascending air flow due to light weight under specific air speed, and impurities with heavy weight can naturally fall down due to being not blown by wind power and are discharged from an impurity discharge port (9) to realize secondary purification;
s3: montmorillonite powder blown out from the purification discharge pipe (6) enters the montmorillonite collection box (7), the montmorillonite powder is blocked by the bag-type filter screen (32) and falls under the action of the vibration motor (34), air is discharged from the air outlet (33), and montmorillonite subjected to secondary purification is left in the montmorillonite collection box (7), so that the purification of montmorillonite is completed.
