Expect the control of primary particle size size.Current common sand milling type mainly has disk type, eddy current type, stick pin etc., in production
The sand mill majority used is all the iterative cycles grinding by material until reaching grind size, more
The material for reaching grind size is still driven into that sand mill continues grinding or the material of not up to grinding precision is discharged in advance, this causes
Material size is distributed widthization, and size distribution peak type precision is uncontrollable, and production efficiency is low, production energy consumption is high.
Utility model content
The utility model technical issues that need to address are: providing that a kind of design is simple, control precision is high, high production efficiency
Grading discharge be sanded machine equipment, narrow grinding after product granularity distribution peak type, greatly promote the production efficiency of product.
In order to solve the above technical problems, the technical solution adopted in the utility model is: a kind of grading discharge sand mill, including
Sand mill main body, rotor, motor, the sand mill lower body part are provided with fines discharge port, and the sand mill main body is hollow
Structure, is provided with separator in the sand mill main body hollow cavity, and the output end of the motor passes through transmission device and described
Armature spindle is connected, and the rotor enters from sand mill main body one end, is fixedly mounted in sand mill body cavity, the rotor is
Hollow sandwich structure by rotor outside sandwich, rotor intraformational bed and is mounted on the stick pin bank of rotor outer surface into the rotor outer clip
It is provided with coarse fodder discharge port on layer, rotor intraformational bed bottom is provided with feed inlet, the rotor and material circulating system phase
Connection.
Preferably, cooling system interlayer is provided in the sand mill main body.
Preferably, the sand mill main body inner wall is coated with erosion shield.
Preferably, filter screen is provided on the coarse fodder discharge port and feed inlet.
Preferably, the stick pin is distributed perpendicular to rotor.
Preferably, the stick pin can be multilayer.
Preferably, the arrangement mode of the stick pin is overlapping or is staggered.
The utility model has the beneficial effects that the utility model carries out grading discharge by classification exit design, to material, reach
Fines to grind size disposably discharges by separator, and the coarse fodder of not up to grind size will do it secondary grinding, this
Classified grinding mode not only greatly improves sand milling efficiency, and the material size distribution that grinding obtains is narrower, realizes more efficient and grain
Degree is distributed narrower grinding effect.

Specific embodiment
As shown in figures 1 to 6, a kind of grading discharge sand mill, including sand mill main body 1, rotor 2, motor 5, sand mill main body
1 lower part is provided with fines discharge port 3, and sand mill main body 1 is hollow structure, is provided with separator 4 in 1 cavity of sand mill main body,
The output end of motor 5 is connected by transmission device 6 with 2 axis of rotor, and rotor 2 enters from 1 one end of sand mill main body, is fixedly mounted on
In the cavity of sand mill main body 1, rotor 2 be hollow sandwich structure, by rotor outside sandwich 21, rotor intraformational bed 22 and be mounted on turn
The stick pin 23 of sub- outer surface forms, and is provided with coarse fodder discharge port 25 on rotor outside sandwich 21,22 bottom of rotor intraformational bed is provided with
Feed inlet 24, rotor 2 are connected with material circulating system 7.
When the utility model is used, material enters rotor by material circulating system 7 after sand mill main body 1 starts
Intraformational bed 22 is entered in 1 cavity of sand mill main body by feed inlet 24 and is ground, and motor 5 drives rotor 2 to carry out high speed rotation
Turn, the stick pin 23 on rotor 2 drives abrasive media and material movement, is sheared, collided, ground to material, so that material
Grain becomes smaller.The small particles material for reaching design fineness is thrown out of first, is filtered through separator 4, is passed through 1 lower part of sand mill main body
Fines discharge port 3 is discharged, and the large granular materials of not up to design granularity are again introduced into rotor outside sandwich by coarse fodder discharge port 25
In 21, material circulating system 7 is returned to by Matter Transfer, and is again introduced into sand mill main body 1 and carries out grinding until reaching design
Granularity.
Separator 4 is the filter device with several gaps, between grinding cavit and rotor, plays separation particle
Purpose.Due to the effect of centrifugal force and separator 4, during the grinding process, bulky grain is intended to concentrate on centre, little particle
It is intended to concentrate on marginal portion, therefore coarse fodder discharge port 25 is arranged close to grinding cavit centre, more conducively collects big
Grain carries out secondary grinder；The design of fines discharge port 3 is in 1 outside left of sand mill main body, more conducively the separation row of small particles material
Out.
One as the present embodiment specifically optimizes example, is provided with cooling system interlayer in sand mill main body 1, is more advantageous to
Timely heat dissipation in process of lapping.
Preferably, the sand mill main body inner wall be coated with erosion shield, prevent with material in material contact process
Corrode sand mill main body.
Preferably, it is provided with filter screen on the coarse fodder discharge port and feed inlet, it can preferably according to actual needs
Determine grind size.
Preferably, the stick pin is distributed perpendicular to rotor.
Preferably, the stick pin can be multilayer.
Preferably, the arrangement mode of the stick pin is overlapping or is staggered.
This multilayer vertical arrangement can reach better grinding effect.
The embodiments of the present invention are described in detail above, but content is only the preferable implementation of the utility model
Example, should not be considered as limiting the scope of the present invention.Impartial change made according to the scope of application of this utility model
Change and improve etc., it should still belong within the patent covering scope of the utility model.
