Description
Technical field
Chosen to install the present invention relates to crushing material triage techniques field, more particularly to a kind of grinding screen
Put.
Background technology
Pulverizer is the machinery that large-sized solid material is crushed to desired size.Pulverizer by
The device such as coarse crushing, in small, broken bits, wind model constitute, reached in the form of high-speed impact pulverizer it
Purpose, using wind energy once into powder, eliminates traditional screening sequence, mainly using mine,
In various industries such as building materials.Put in crushing process material external force include pressure rolling, shearing,
Impact strike, grinding.Pressure rolling be used primarily in slightly, in it is broken suitable for the broken of hard material and big block
Broken, shearing is used primarily in broken or crushing and is suitable to the crushing of toughness or fibroid material, and impact is beaten
Hit and be used primarily in crushing and depolymerization is suitable to the crushing of brittle material, grinding it is main ultra-fine grinding with
And ultramicro grinding is suitable to the ultramicro grinding after middle finess disintegrating.Coating in process of manufacture,
Need to crush material, existing reducing mechanism crushing operation is complicated, crush efficiency is low,
Influence the processing efficiency of coating.
The content of the invention
The present invention is complicated for above-mentioned reducing mechanism crushing operation, and the low defect of crush efficiency is asked
A kind of topic, there is provided crushing and screening device, powder drives feed screw through silo by feeding motor
Feeding primary abrasive mouthful, main mill mill high speed circumference elliptical gear powder, makes powder attrition grinding,
Clasfficiator is classified to powder, and powder is pumped into cyclone separator and is arranged from removal device by air-introduced machine
Go out.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of crushing and screening device, including feeding motor, silo, main mill, clasfficiator, rotation
Wind separator, air-introduced machine, removal device, backflow circle, the feeding motor, frequency converter, material
Bucket, main mill, clasfficiator, cyclone separator, air-introduced machine are sequentially connected, the cyclone separator
It is connected with removal device, the backflow circle is connected between the main mill and clasfficiator；Powder is by feeding
Material motor drives feed screw through silo feeding primary abrasive mouthful, main mill mill high speed circular motion
Impact powder, makes powder attrition grinding, and strong whirlwind is by powder along main mill cavity inner wall feeding classification
Device, powder flows to the classifying turbine of clasfficiator at different rates, and fine powder material smoothly passes through impeller
Piece gap, discharges, meal material as finished product by air-introduced machine suction cyclone separator and from removal device
Kept off by impeller blade, fall into backflow circle, return to main mill, continue attrition grinding.
Further, described device also includes blower fan and air cleaner.
Further, the blower fan is connected with silo and air cleaner, the air filtration
Device is connected with main mill and clasfficiator.
Further, the rotating speed of the main mill mill is 8000r/min.
Further, the feeding motor is variable-frequency stepless speed-regulating motor.
Beneficial effects of the present invention：A kind of crushing and screening device, powder is driven by feeding motor and fed
Material screw rod makes through silo feeding primary abrasive mouthful, main mill mill high speed circumference elliptical gear powder
Powder attrition grinding, clasfficiator is classified to powder, and fine powder material is pumped into whirlwind point by air-introduced machine
From device and from removal device discharge, meal material is kept off by impeller blade, falls into backflow circle, returns to main mill,
Continue attrition grinding；With it is simple to operate, crush efficiency is high the characteristics of.
Brief description of the drawings
Fig. 1 is crushing and screening device schematic diagram of the present invention.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention is realized are easy to
Understand and understand, with reference to being specifically illustrating, the present invention is expanded on further.
During specific implementation, with reference to Fig. 1, a kind of crushing and screening device, including feeding motor, thing
Hopper, main mill, clasfficiator, cyclone separator, air-introduced machine, removal device, backflow circle.Feeding
Motor, frequency converter, silo, main mill, clasfficiator, cyclone separator, air-introduced machine phase successively
Even, cyclone separator is connected with removal device, and the backflow circle is connected between main mill and clasfficiator,
Clasfficiator is controlled by variable-frequency motor.The device also includes blower fan and air cleaner, blower fan difference
It is connected with silo and air cleaner, air cleaner is connected with main mill and clasfficiator respectively.
Powder drives feed screw through silo feeding primary abrasive mouthful, main mill mill by feeding motor
High speed circumference elliptical gear powder is done with the rotating speed of 8000r/min, makes powder attrition grinding.Thing
Material motor is stepless frequency control motor, and crushing pin is provided with main mill mill.Rotate at a high speed
Mill causes that entering air filtering by air cleaner forms strong whirlwind, and strong whirlwind is passed with pin is crushed
The kinetic energy passed is superimposed, acts on powder, makes powder shearing friction, attrition grinding.
Powder after crushing is by strong whirlwind along main mill cavity inner wall feeding clasfficiator.Powder is with difference
Speed flow to the classifying turbine of clasfficiator, the average speed that fine powder material passes through impeller is fast, fine powder
Material smoothly passes through impeller blade gap, as finished product by air-introduced machine suction cyclone separator and from discharge
Device is discharged.The average speed that meal material passes through impeller is slow, and meal material is kept off by impeller blade, falls into
Backflow circle, returns to main mill, continues attrition grinding.Superfine powder through cyclone separator top exit,
It is discharged to pulse dust removal retracting device.
Embodiment described above is only that the preferred embodiment of the present invention is described, and
It is non-that the spirit and scope of the present invention are defined.The premise of design concept of the present invention is not being departed from
Under, all variations and modifications that this area ordinary person makes to technical scheme,
Protection scope of the present invention should be dropped into.
