Description
Technical field
The present invention relates to mine abrasive dust equipment, especially relate to suspension mill.
Background technology
Suspension mill is widely used in the grinding processing of mineral products material in the fields such as metallurgy, building materials, chemical industry, mine.As shown in Figure 3, traditional suspension mill is mainly by being arranged on the abrasive dust main computer unit of casing 1.1 interior bottoms and the Fineness machine unit 2.1 on top forms.Grinding roller assembly in abrasive dust main computer unit is suspended on grinding roller suspension bracket 4.1 by horizontal axis tam 3.1, grinding roller suspension bracket 4.1 is fixedly connected with main shaft 5.1 and relieving tool post 6.1, compression spring 7.1, in cantilever 8.1 outer faces of grinding roller bearing chamber, forces grinding roller 9.1 to be pressed on bull ring 10.1 internal circular surfaces taking horizontal axis tam 3.1 as fulcrum; In the time that motor 11.1 drives main shaft 5.1 to rotate by transmission device, be contained in perching knife 12.1 and grinding roller 9.1 synchronous rotaries on relieving tool post 6.1, grinding roller 9.1 rotation when bull ring 10.1 inner headed faces roll.When work, material is fallen bull ring 10.1 internal circular surfaces (grinding working face) from being opened in the charging aperture 13.1 being positioned on bull ring 10.1 top chassis sidewalls, reaches pulverizing object by the rolling of grinding roller 9.1.Material after pulverizing is under the blasting action from air intake spiral case 14.1, move to top from casing 1.1 bottoms and be brought into Fineness machine unit 2.1 and carry out sorting, the excessively thick material of fineness falls back to bull ring 10.1 internal circular surfaces and refaces, qualified fine powder enters with air-flow the whirlwind powder collector being communicated with Fineness machine unit 2.1 air outlets, discharges and is finished product through flour extraction pipe.The wheel speed of Fineness machine 2.1 is higher, and the powder sub-electing is thinner.The deficiency that above-mentioned traditional suspension mill exists is: 1, charging aperture 13.1 is arranged on grinding roller suspension bracket 4.1 and grinds on casing 1.1 sidewalls between working face, make just to enter the concentrated grinding working face that is positioned at charging aperture 13.1 belows that drops to of material of flour mill, the broken impulsive force that causes the thickness of feed layer at this position and bear is greater than other positions and grinds working face, when rolling, grinding roller 9.1 rotation brings out intermittent vibrations by herein time, for reducing intermittent vibrations, have to reduce inlet amount or reduce grinding roller suspension bracket 4.1 rotating speeds, keep the stationarity of flour mill work to reduce flour mill output.2, when the granule content that is less than 0.315mm when particle diameter in material is greater than 10%, the bed of material that grinds working face can the attenuation gradually along with increasing of accounting, the vibrations that produce when flour mill grinds also strengthen thereupon gradually, running can cause parts damage by force, the same deficiency that keeps flour mill stable working to reduce grinding roller suspension bracket 4.1 rotating speeds that exists.
Summary of the invention
The object of the invention is to provide a kind of suspension mill.
For achieving the above object, the present invention takes following technical proposals:
Suspension mill of the present invention, comprises the suspension mill body forming by being arranged on the abrasive dust main computer unit of chassis cavity bottom and the Fineness machine unit on top; In casing between described abrasive dust main computer unit and Fineness machine unit, be provided with the equal material unit of charging; The equal material unit of described charging is by the diffusion separator being arranged on chassis cavity support, and discharging opening is positioned at the feed pipe composition of described diffusion separator top, and the charging aperture of described feed pipe is positioned at outside casing.
Described diffusion separator comprises the bevel gear gearbox being arranged on described support, and the power output shaft of described bevel gear gearbox seals vertically upward outside the housing that extends bevel gear gearbox and with material toggling dish and is fixedly connected with; The power input shaft of bevel gear gearbox is extended outside described casing and with belt pulley and is fixedly connected with by axle sleeve horizontal seal.
Described diffusion separator is by the sealed electric-motor being arranged on vertically upward on described support, and the material toggling dish being horizontally fixed on described sealed electric-motor motor shaft forms.
Advantage major embodiment of the present invention is in the following areas:
1, in the casing between described abrasive dust main computer unit and Fineness machine unit, be provided with the equal material unit of charging, and the discharging opening of described feed pipe is arranged on and is positioned at described diffusion separator top; Therefore material enters after casing with first there being diffusion separator to carry out the separation of thickness powder, diffusion, fine powder is under the blasting action in air intake spiral case, move up directly enter Fineness machine unit separation and collection and not with coarse granule material participate in grind, abrasive dust main computer unit only grinds broken to coarse granule material, greatly improved the mechanical efficiency of abrasive dust main computer unit; Meanwhile, the fine powder in charging aperture enters casing in material directly enters the unit sorting of Fineness machine, and the air content that also makes to grind in the working face bed of material reduces, and is conducive to thicker, the more closely knit bed of material and forms, and reaches and improves grinding efficiency object.
2, the coarse granule material after diffusion separator separates prolongs chassis sidewall and evenly falls to grinding working face, uniform feeding, fragmentation, the grinding of grinding working face are realized, the intermittence vibrations of having avoided traditional suspension mill to concentrate place charging to bring out, the rotating speed that makes the operation of abrasive dust main frame more steadily also can improve grinding roller suspension bracket obtains higher output.
3, the present invention first carries out the grinding technics design of coarse granule material to the material entering in casing after separating, spreading again, be particularly suitable for the mixed material processing that granule content accounting that particle diameter in material is less than 0.315mm is greater than 30%, such as flyash, building stones factory chip raw material etc.And traditional suspension mill flour mill must can not be worked when entering in casing particle diameter in material and be less than when the particulate material content accounting of 0.315mm being greater than 15% in shutdown, otherwise running will cause parts damage by force.
