Description
Technical field
The present invention relates to milling equipment, be specially a kind of fine powder mill.
Background technology
The operation principle of flour mill is that the grinding roller of Burnisher apparatus is rolled on bull ring, by shoveling under centrifugal action tightly
Cutter scoops up material and delivers to grinding roller and the region of milling of bull ring formation, and material is broken into powder, then under the effect of grinding roller grinding pressure
Become the material of powder to blow afloat machine by analysis in the district that mills under the effect of blower fan, reach the material of fineness requirement by analyzing
Machine, the material not reaching requirement is returned district's continuation grinding of milling, is entered the collection of cloth bag catcher by analyzing the material of machine.
Economical and practical type flour mill is raymond mill, can only produce the thickness powder of below 400 mesh under its traditional structure, and
The powder body of fineness higher level to be produced, as produced 400 mesh～the fine powder of 1250 mesh, then needs to use the higher ring of cost performance
Roller flour mill or impact grinder etc., cause financial burden to Producer.
Summary of the invention
For the deficiencies in the prior art, the technical problem to be solved is to propose one to be carried out by conventional types
Transform and the flour mill of fine powder can be produced.
Can solve the problem that the fine powder mill of above-mentioned technical problem, its technical scheme includes base and is installed on base top
Cover cylinder, described cover cylinder top is provided with grading plant, is provided with and sets up at the spindle gearing of base bottom in cover cylinder, described
Spindle gearing drives Burnisher apparatus by grinding roller frame, is provided with the grinding roller with Burnisher apparatus and forms the district that mills in described base
Bull ring and the spade blade device driven by relieving tool post by grinding roller frame, except that also include air-intake device, described air-intake device
The district that mills in base is made to become airtight mill room above the district that mills around the setting of cover cylinder, the two or more air intake of air-intake device
Mouth circumference uniform distribution is opened on cover cylinder.
For avoiding interfering, need to stagger the charging aperture offered on cover cylinder in the position of described air outlet.
Conventionally, described air-intake device is arranged less than grinding roller frame.
The grinding roller impact to bull ring when milling for slowing down, corresponding to each grinding roller assembly of circumference local in Burnisher apparatus in mill
Grinding roller buffer unit is set in roll stand, described grinding roller buffer unit be included in the grinding roller sleeve of grinding roller assembly relative with on grinding roller frame and
The grinding roller sleeve riser put and grinding roller erect plate, are equipped with bolt, described bolt between described grinding roller sleeve riser and grinding roller erection plate
On forward and backward spring base between be provided with low elastic spring, bolt is combined with the nut acting on spring base, described nut is by low
Corresponding grinding roller is pressed to bull ring on the riser of respective side by elastic spring pretension.
Beneficial effects of the present invention:
1, return air region is separated by fine powder mill of the present invention with the district that mills, and alleviates the powder body ascension in the district that mills with this,
The thickness powder making quality bigger is difficult on box haul drift about and be deposited on the district that mills and repeatedly mill and become fine powder, and light weight
Fine powder under the guiding of return air stream, entered graded region with the wind, be fine powder by the overwhelming majority of graded region classification
And the most a small amount of thickness powder, the situation of the most a small amount of fine powder is complete for thickness powder for the overwhelming majority collected with traditional structure
On the contrary.
2, the present invention is best suitable for having transformed in the existing traditional structure of Raymond machine, and low cost is effective, and income is high,
Material of milling is in extensive range.
