step two: when the stirring rod (54) rotates, the stirring paddle (591) is utilized to stir the steel balls at the lowest layer, so that the grinding is more uniform, and the grinding effect of the device is improved;

step three: while grinding, a worker twists the threaded rod (898) to enable the threaded rod (898) to drive the second bevel gear (899) to rotate, so as to drive the first bevel gear (897) meshed with the threaded rod to rotate, the worm (893) is driven to rotate by the rotation of the first bevel gear (897), the lower end of the worm (893) is embedded in the second bearing (10), so that the worm (893) can be effectively rotated, and the worm block (891) of the thread on the surface of the worm block is driven to move downwards or upwards when the worm (893) rotates, so that the inclination angle of the screening plate (82) can be adjusted, the left side of the screening plate (82) is clamped in the fixing block (86), and the fixing block (86) is hinged to the outer surface of the first supporting rod (81) by the hinge (89), so that the angle of the screening plate (82) can be effectively inclined, and the screening effect on steel balls is facilitated;

step four: after the regulation is accomplished, upwards rise through control electric telescopic handle (51), make it utilize connecting rod (52) and the connected mode of rotating motor (53) to upwards lift rotation motor (53), stop block (58) at the in-process puddler (54) lower extreme that lifts break away from out opening (6), thereby can fall into to screening board (82) through opening (6) with the steel ball after polishing on, thereby divide the sieve to the steel ball, easy operation improves work efficiency.
