Wet ball mill for manufacturing flaky zinc powder

Abstract

The invention relates to the technical field of grinding, and discloses a wet-type ball mill for scaly zinc powder manufacturing, the wet-type ball mill comprises two symmetrical fixed seats, one end of each fixed seat is fixedly connected with a feeding pipe, a grinding cylinder is movably connected between the two fixed seats in a sleeving manner, the outer side surface of the grinding cylinder is provided with driven teeth which are uniformly distributed, and the driven teeth are arranged on the outer side surface of the grinding cylinder. And a motor and a driving gear I are arranged on one side of the grinding cylinder. Long teeth on a belt are intermittently meshed with driven teeth to drive a grinding cylinder to quickly rotate by 90 degrees and then stop rotating, so that a metal plate perpendicular to the ground is turned to be parallel to the ground, and grinding balls and slurry located on one side of the rotating direction of the metal plate are thrown upwards and are thrown down in the rotating direction under inertia force; the grinding balls and the slurry are spread out and fall to the metal plate, part of the slurry falls to the lower processing cavity from the through holes, the grinding balls impact and grind thin-layer slurry, and the situation that the slurry is accumulated, so that the grinding balls are buffered by the upper slurry when falling to the slurry, and the lower slurry cannot be effectively ground is avoided.

Description

technical field [0001] The invention relates to the technical field of grinding, in particular to a wet ball mill for manufacturing scaly zinc powder. Background technique [0002] For the manufacture of scaly zinc powder, atomization method and ball milling method are mostly used. The ball milling method adopts a wet ball mill. The atomized zinc powder, aliphatic hydrocarbon solvent and a small amount of lubricant are placed in the ball mill to form a solid-liquid mixed slurry. During the rotation of the ball mill, the grinding balls are raised and dropped to the slurry inside the ball mill at a high place, and the slurry is fully ground to make a zinc powder slurry with a scale structure. [0003] In this process, when the grinding ball falls to the slurry, it will first contact the top of the slurry, so that most of the impact force is absorbed by the top of the slurry, so that the bottom of the slurry cannot get the effective impact of the grinding ball, which will lead ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing wet ball mill proposed in the background technology, the present invention provides a wet ball mill for the production of flaky zinc powder, which has intermittent The type drives the grinding cylinder to rotate so that the slurry and the grinding balls are thrown away. When the grinding cylinder stops rotating, the grinding balls and the slurry are thrown to the metal plate. The slurry is spread on the metal plate to form a thin layer, and the grinding balls can effectively impact and grind the thin layer of slurry. The grinding ball hits the metal plate to make it vibrate, the vibrating metal plate squeezes and grinds the slurry in the gap with the partition plate, the weight difference between the two sides of the metal plate makes the grinding cylinder rotate, the slurry and the grinding ball converge to the bottom of the metal plate again, The rolling of the grinding ball frictionally grinds the slurry, the partition plate falls to the bottom of the metal plate again under its own weight to form a relatively sealed plate, and the protruding column hits the opening of the through hole to make the metal plate vibrate, which solves the problems raised in the above background technology. The technical problem that the grinding ball cannot effectively impact the slurry due to the thick accumulation of the slurry
