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

Ball mill

Technical field

The present invention relates to a kind of ball mill that is used for wet method medium dispersion grinding, belong to the plant equipment field.

Background technology

Ball mill comprises support, abrasive barrel, cooling cylinder, seal cover, mill, feed pipe, discharge nozzle, water inlet pipe, outlet pipe, goes out material screen, rotating shaft, Connection Block, seal, bearing block and bearing at present; Bearing block is installed on the support, and the rotating shaft rear end is installed on the bearing block through bearing, and abrasive barrel is sleeved on the rotating shaft front end; Cooling cylinder is sleeved on the abrasive barrel outside, and seal cover is encapsulated in abrasive barrel and cooling cylinder front end, and material screen is installed out in inside, abrasive barrel rear end; Connection Block is installed the rear end that is connected abrasive barrel and cooling cylinder; Seal is installed in the rotating shaft in the Connection Block, and some mills are installed in the rotating shaft in abrasive barrel, is connected with discharge nozzle and water inlet pipe on the cooling cylinder; Feed pipe is installed on the seal cover and with abrasive barrel and communicates, and discharge nozzle is installed in out the abrasive barrel rear end in the material screen outside.In work is earlier the zirconium pearl to be put into; The material that will grind then is through feed pipe input abrasive barrel, and mill rotates under the drive of motor through rotating shaft, and mill drives the zirconium pearl material is sheared; Grinding material thus; The material that mill is good is exported by discharge nozzle after going out material screen, and cooling water is got in the cooling cylinder by water inlet pipe abrasive barrel is cooled off, and is flowed out by outlet pipe then; Because the impulse force when material gets into abrasive barrel by feed pipe is bigger; Thus a large amount of white pearls all are flushed to the abrasive barrel rear end, make white pearl a large amount of be deposited in the abrasive barrel rear end, make that abrasive barrel rear end caloric value is especially big; And have only a spot of white pearl to exist at abrasive barrel; Make material can't effectively be ground at the abrasive barrel front end thus, also make the grinding efficiency of material not high thus, the grinding uniformity of material is bad.

Summary of the invention

To above-mentioned shortcoming, the object of the present invention is to provide a kind ofly can make white pearl in abrasive barrel, evenly distribute, can improve grinding efficiency and grind inhomogeneity ball mill.

Technology contents of the present invention does, a kind of ball mill, and it comprises support, abrasive barrel, cooling cylinder, seal cover, mill, feed pipe, discharge nozzle, water inlet pipe, outlet pipe, goes out material screen, rotating shaft, Connection Block, seal, bearing block and bearing; It is characterized in that on mill, being provided with some water droplet shape through holes, the inwall of water droplet shape through hole is provided with inclination angle beta, and inclination angle beta is 40 °～70 °.

In order to reduce the direct impact of material, be convenient to being evenly distributed on of zirconium pearl and comprise also in the ball mill that material separating disc, material separating disc are installed in the front end of the rotating shaft in the abrasive barrel the zirconium pearl; The charging aperture of feed pipe is corresponding with material separating disc, and the material that promptly gets in the abrasive barrel from charging aperture can be sprayed onto on the material separating disc; For further reducing the impulsive force of material, on material separating disc, be provided with a bulge loop, the charging aperture of feed pipe is corresponding with the bulge loop inboard, and the material that promptly gets in the abrasive barrel from charging aperture can be sprayed onto on the material separating disc in the bulge loop.

For improving cooling effect of the present invention, be wound with cooling water pipe at the outer wall of abrasive barrel, cooling water pipe one end is communicated with water inlet pipe, and the cooling water pipe other end is communicated with outlet pipe.

The advantage that the present invention is compared with prior art had is: the present invention can progressively be pushed to front end from the zirconium pearl of abrasive barrel rear end through water droplet shape through hole with the zirconium pearl through the water droplet shape through hole that inwall on mill has the angle of inclination; Thereby make the zirconium pearl evenly be distributed in the abrasive barrel; Avoid the zirconium pearl at the bulk deposition of abrasive barrel rear end and a large amount of heats of production thus; The grinding efficiency of material is improved, the grinding good uniformity of material; Around through material separating disc feed separation being arrived simultaneously, thereby reduce the direct impact of material to the zirconium pearl, can the more effective even distribution of being convenient to the zirconium pearl.

Specific embodiment

Like Fig. 1, Fig. 2 and shown in Figure 3; A kind of ball mill, it comprises support 1, abrasive barrel 2, cooling cylinder 3, seal cover 4, mill 5, feed pipe 6, discharge nozzle 7, water inlet pipe 8, outlet pipe 9, goes out material screen 10, rotating shaft 11, Connection Block 12, seal 13, bearing block 14 and bearing 15; It is characterized in that in ball mill, also comprising material separating disc 16, material separating disc 16 is installed in the front end of the rotating shaft 11 in the abrasive barrel 2; On material separating disc 16, be provided with a bulge loop 16.1, the charging aperture of feed pipe 6 is inboard corresponding with bulge loop 16.1; On mill 5, be provided with some water droplet shape through holes 5.1, the inwall of water droplet shape through hole 5.1 is provided with inclination angle beta, and inclination angle beta is 55 °; Outer wall at abrasive barrel 2 is wound with cooling water pipe 17, and cooling water pipe 17 1 ends are communicated with water inlet pipe 8, and cooling water pipe 17 other ends are communicated with outlet pipe 9.

Operation principle of the present invention does, the zirconium pearl is put into abrasive barrel 2, and mill 5 rotates under the drive of motor 18 through rotating shaft 11, and cooling water is got in the cooling tubes 17 by water inlet pipe 8 abrasive barrel 2 is cooled off, and is flowed out by outlet pipe 9 then; Material is ejected in the bulge loop 16.1 of material separating disc 16 by the charging aperture of feed pipe 6, by material separating disc 16 material is disperseed away then; The zirconium pearl is ground the material that is disperseed to come out by material separating disc 16 under the drive of mill 5; The material that mill is good is exported by discharge nozzle 7 through going out material screen 10 backs; Simultaneously part zirconium pearl can since material backward flowability and taken to abrasive barrel 2 rear ends by material, part zirconium pearl progressively is transported to abrasive barrel 2 leading portions through the water droplet shape through hole 5.1 on the mill 5 again then.
