Bead mill

Abstract

The invention relates to a bead mill. The bead mill comprises a base, an abrasive barrel, a cooling barrel, a seal cover, an abrasive disk, a feed pipe, a discharge pipe, a water inlet pipe, a water outlet pipe, a discharge screen, a rotating shaft, a connecting seat, a sealing element, a bearing block and a bearing. The bead mill is characterized in that a plurality of water drop-shaped through holes are formed in the abrasive disk, the inner wall of each water drop-shaped through hole has an inclined angle beta, and the inclined angles beta are between 40 degrees-70 degrees. The bead mill has the advantages that zirconium beads can be uniformly distributed in the abrasive barrel, and the grinding efficiency and grinding uniformity can be improved.

Description

technical field [0001] The invention relates to a bead mill used for wet medium dispersion grinding, which belongs to the field of mechanical equipment. Background technique [0002] At present, the bead mill includes machine base, abrasive cylinder, cooling cylinder, sealing cover, grinding disc, feed pipe, discharge pipe, water inlet pipe, water outlet pipe, discharge screen, rotating shaft, connecting seat, seal, bearing seat and bearing; The bearing seat is installed on the machine base, the rear end of the rotating shaft is installed on the bearing seat through the bearing, the abrasive barrel is set on the front end of the rotating shaft, the cooling barrel is set on the outside of the abrasive barrel, the sealing cover is sealed on the front end of the abrasive barrel and the cooling barrel, and the rear end of the abrasive barrel is inside Install the discharge screen, the connecting seat is installed and connected to the rear end of the abrasive cylinder and the coo...

AI Technical Summary

Problems solved by technology

The work is to put the zirconium beads in first, and then input the material to be ground into the grinding cylinder through the feed pipe, the grinding disc rotates under the drive of the motor through the rotating shaft, and the grinding disc drives the zirconium beads to cut the material, thereby grinding the material, grinding The good material is output from the discharge pipe after passing through the discharge screen, and the cooling water enters the cooling cylinder from the water inlet pipe to cool the abrasive cylinder, and then flows out from the water outlet pipe; since the material enters the abrasive cylinder through the feed pipe, the momentum is relatively large, As a result, a large number of pearls are rushed to the rear end of the abrasive barrel, so that a large number of pearls are accumulated at the rear end of the abrasive barrel, which makes the rear end of the abrasive barrel generate a large amount of heat, while only a small amount of pearls exist in the abrasive barrel, thus making the material Effective grinding cannot be obtained at the front end of the abrasive barrel, which also makes the grinding efficiency of the material not high, and the grinding uniformity of the material is not good
