The utility model discloses a kind of mills for the grinding of superfinishing powder, it includes cylindrical upper mill and lower mill, the upper mill and lower mill all have abradant surface, the upper mill and lower mill all have the centre bore of perforation, and the abradant surface of the upper mill and lower mill is equipped with several grinding grooves extended from centre bore described in its to its fringe radiation shape, the grinding groove has two sidewalls, and the two sidewalls of the grinding groove are not orthogonal to the abradant surface.The mill for the grinding of superfinishing powder of the utility model is designed using special structure, so that material enters from centre bore, by grinding the grinding between the gradually smaller abradant surface of spacing up and down, finally it is discharged from edge, its material for being particularly suitable for grinding relatively fine particle, is suitable for being widely popularized.
Description
Technical field
The utility model relates to a kind of mills, in particular for the mill of superfinishing powder grinding.
Background technique
Field of machining has the machinery of many comminuting matters, and the material being related to includes the food of powdery, lithium battery row
Raw material powder of industry etc..Grinding for micron-sized superfinishing powder, there are many relevant research, how to design reasonable, particle
Spend adjustable, anti abrasive abrasive structure is research object of the invention.
Summary of the invention
In order to overcome the above problem, it is small, anti abrasive for superfinishing powder that the utility model provides a kind of abrasive grains granularity
The mill of grinding.
The technical solution of the utility model is to provide a kind of mill for the grinding of superfinishing powder comprising cylindrical upper mill
With lower mill, the upper mill and lower mill all have abradant surface, it is characterised in that: the upper mill and lower grind the center of perforation of all having
Hole, and the abradant surface of the upper mill and lower mill is equipped with several grindings extended from centre bore described in its to its fringe radiation shape
Slot, the grinding groove have two sidewalls, and the two sidewalls of the grinding groove are not orthogonal to the abradant surface.
Preferably, the abradant surface of the upper mill and lower mill is provided with grinding groove described in several groups, described in same group
Grinding groove is mutually parallel, and the grinding groove between adjacent sets is not parallel.
Preferably, the angular range between the grinding groove between adjacent sets is 30~70 °.
Preferably, it is described it is upper mill and lower mill abradant surface be provided with six groups described in grinding groove.
Preferably, the abradant surface of the upper mill and lower mill is arcwall face, and the thickness of the upper mill and lower mill is by its side
Edge is gradually reduced in heart hole thereto.
Preferably, the edge of the abradant surface of the upper mill and lower mill all has the planar portions of an annular, described after installation
Gap between upper mill and the planar portions of lower mill is adjustable.
Preferably, the upper mill and lower mill are made of silicon nitride, silicon carbide or aluminum oxide.
The mill for the grinding of superfinishing powder of the utility model is designed using special structure so that material from centre bore into
Enter, by grinding the grinding between the gradually smaller abradant surface of spacing up and down, is finally discharged from edge, it is thinner to be particularly suitable for grinding
The material of particle is suitable for being widely popularized.
Detailed description of the invention
Fig. 1 is the top view of the upper mill of the best embodiment of the utility model；
Fig. 2 is the sectional view along A-A of Fig. 1.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below.
As illustrated in fig. 1 and 2, a kind of mill for the grinding of superfinishing powder of the utility model includes cylindrical 10 He of upper mill
Lower mill (not shown), upper mill 10 is identical with lower mill structure or very approximate (only because the reasons such as assembly slightly adjust), thus this theory
Bright book only provides the structural schematic diagram of mill 10.Upper mill 10 and lower mill all have abradant surface 14, and upper mill 10 and lower mill all have and pass through
Logical centre bore 12.Upper mill 10 and the abradant surface 14 of lower mill are arcwall face, the thickness of upper mill 10 and lower mill from its edge to
Its centre bore 12 is gradually reduced.
The edge of the abradant surface 14 of upper mill 10 and lower mill all has the planar portions 16 of an annular, and the upper mill 10 after installation is under
Gap between the planar portions 16 of mill is adjustable.After installation, 10 or lower mills of upper mill are fixed, another is then motor (not shown)
Lower high speed rotation is driven, to realize grinding.Material enters from centre bore 12, is then ground between abradant surface 14, finally
It is discharged from planar portions 16, the granularity of particle is controlled by the gap on adjusting between mill 10 and the planar portions 16 of lower mill.
The abradant surface 14 of upper mill 10 and lower mill is equipped with 6 groups of grinding grooves 18, and every group all includes several grinding of being parallel to each other
Slot grinding 18, grinding groove 18 from its centre bore 12 to its fringe radiation shape extend, grinding groove 18 have two sidewalls, the two of grinding groove 18
Side wall is not orthogonal to abradant surface 14, and the angular range between grinding groove 18 between adjacent sets is 30~70 °.Multiple groups are set
Grinding groove 18 is conducive to generate turbulent flow, improves the efficiency of grinding；It also contributes in process of lapping, the material of high speed rolling is by gas
It streams in the grinding groove 18 of different angle.Grinding groove 18 is processed to tilt angle, helps so that notch is in high speed and turns
Become sharp blade during dynamic, to reinforce the crushing to material.
Further, the abradant surface 14 of upper mill 10 and lower mill is coated with silicon nitride coating or upper mill 10 and lower mill by nitrogen
Silicon nitride material is made, to improve wearability.
Above embodiments are only the one such embodiment of the utility model, and the description thereof is more specific and detailed, but simultaneously
Therefore it cannot be interpreted as that a limitation on the scope of the patent of the present invention.It should be pointed out that for the ordinary skill of this field
For personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this
The protection scope of utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
