[0002] In the related technology, an ultrafine ball mill for producing ultrafine powder is disclosed with publication number CN217093740U, which specifically relates to the technical field of ball mills. When the micro-grinding body of the ball mill grinds the material, the material cannot fall directly on the grinding ball when feeding, so that the grinding ball cannot fully grind the material. The ball mill comprises a grinding chamber, a drop barrel is installed at the bottom of the grinding chamber, grinding balls are arranged inside the grinding chamber, a first fixed cylinder is installed at the top of the grinding chamber, a turntable is rotatably arranged inside the first fixed cylinder, a conical funnel is installed at the top edge of the turntable, and a second fixed cylinder is installed above the first fixed cylinder.

[0003] The existing ball mill does not screen the raw materials after grinding them, so that the quality of the products cannot be effectively controlled, which will increase the generation of waste, reduce resource utilization and increase production costs. Utility Model Content

[0004] The utility model aims to provide an ultrafine ball mill for producing ultrafine powder, which solves the problem that the quality of the product cannot be effectively controlled without screening, which will increase the generation of waste, reduce resource utilization and increase production costs.

[0014] 1. The utility model sets a screening mechanism. When the ground raw materials need to be screened, the motor can be started, and the motor will drive the rotating shaft 1, the worm, the pinion and the pulley to rotate synchronously. Since the worm is meshed with the worm wheel, the worm can drive the worm wheel to rotate when the worm rotates, so that the turntable of the rotating shaft 2 can rotate during the rotation process, and the turntable cooperates with the round rod to produce an eccentric shaft effect during the rotation process, so that the connecting rod can drive the sliding rod and the filter screen on the sliding rod to move up and down in the two slide grooves on the material distribution box. The ground raw materials are screened by the filter plate, which can effectively control the quality of the product, reduce the generation of waste, improve resource utilization, and reduce production costs.

[0015] 2. The utility model sets a grinding mechanism. Since the small gear meshes with the large gear, the small gear can drive the large gear to rotate synchronously when it rotates, so that the ball mill can be driven to rotate. During the rotation of the pulley, the pulley will also synchronously drive another pulley through the belt, so that during the rotation of the rotating shaft three, it can drive two grinding discs and multiple grinding balls to be affected by centrifugal force, forming high-speed motion on the grinding discs, rubbing, colliding and grinding with the raw materials, and during the rotation of the grinding discs, the ball mill will also reverse. The reverse ball mill can change the friction mode and grinding path between the grinding balls and the grinding discs, which helps to improve the grinding effect.
