The specific embodiment
Milling apparatus shown in the accompanying drawing comprises that its installation is used for using vertically-orientedly by support housing 2,3,4,5,6,7,8,9 and 10 fixing main drive shafts 1.Axle 1 drives by the main drive motor (not shown) by belt wheel and band, described main drive motor be in operation single speed or variable-ratio.Axle 1 carries centrifugal grinding separator 19,20,21,22,23,24,29,30,31 and 34 in its lower end.This axle passes seal casinghousing 11,12,13,14,15,16,17 and 18 equally.
According to the utility model, centrifugal grinding separator comprises three major parts: have the top rotating disc 20/22 of groove, middle rotating ring 23 and bottom rotating disc 24.Bottom rotating disc 24 has the groove 31 and the single centre bore 31a of a plurality of oblique formation.The top rotating disc has the part 20 of inclination, and the part 20 of this inclination has the groove 21 of a plurality of oblique formation.A plurality of friction pin (attrition peg) 28,34 are coupled to the outward flange of centrifugal grinding separator.Middle rotating ring 23 has the groove 30 of a plurality of oblique formation.Parts 20,22,23,24,29,30,31,31a and 34 are assembled to form centrifugal grinding separator.
Centrifugal grinding separator has (cap head) screw (not shown) of nut to be fixed to axle 1 by a plurality of.
Main grinding chamber 27,28a and 33a suspend from seal casinghousing, and seal casinghousing carries a plurality of shaft sealers 12, and utilize liquid wash by suitable hole (not shown).
Grinding chamber is equipped with a plurality of static friction pin 28 and cooling water sleeve 26 and chuck 25.In use, grinding chamber partly utilizes known technology to fill with the abrasive material of granular materials or abrasive material with the diameter between 0.1 millimeter to 3 millimeters.Material to be ground is caught to flow respectively to pass suitable entrance and exit hole 32 and 35, and is directed into the positive center of centrifugal grinding separator.Simultaneously, motor is operated with rotating shaft 1, thereby makes centrifugal grinding separator produce suitable strong agitation, shearing, friction and released state in grinding chamber.The centrifugal grinding separator of rotation makes material to be ground outwards be forced to, enter and pass abrasive material.Prevent that at material to be ground and the centrifugation on the abrasive material abrasive material from spilling by centrifugal grinding separator.Heavier abrasive material is pulled back in the centrifugal grinding separator by the effect of the groove of oblique formation in last rotating disc 22 and the lower rotating disc 24.
Above-described milling apparatus has the centrifugal grinding separator shown in the formation of resulting from and several advantages of grinding chamber.
Improve and strong abrasive material pressure is created between the wall of the edge of centrifugal grinding separator and grinding chamber, and this causes the grinding efficiency that improves.
The high strength abrasive areas of smaller size smaller produces.
In the whole process of operation, the efficient by centrifugal grinding separator keeps abrasive areas, makes abrasive material with predetermined circulatory motion action, and concentrate on centrifugal grinding separator inward flange and outer peripheral around.
Friction pin is provided with like this to cause maximum abrasion friction effect in the inward flange of the centrifugal grinding separator of rotation and outward flange and static upper and lower grinding chamber dish.Strong abrasive power is created between the pin 29,34 and static pin 28,33 of rotation.
Because realized the tangible separation of abrasive material, therefore do not need second-stage separation device from product to be ground.
Shown in Fig. 2 and 3, a plurality of grinding chambers and the centrifugal grinding separator assembly that interrelates can cooperate the effect that forms layering together.Every layer of abrasive areas with it, permission are used the abrasive material of specific dimensions in each grinding chamber.For example, the abrasive material with 2 mm dias can be used in first assembly, and the abrasive material with 1 mm dia can be used in second assembly, and the abrasive material with 0.5 mm dia can be used in the 3rd assembly.Effectively, Fig. 2 and a milling apparatus of 3 have three independent grindings and separated region.Material to be ground passes assembly 1, assembly 2, and passes assembly 3 at last.
Less abrasive material volume will be used.
Being reduced on the material to be ground of smaller particles size obtains, the grain products that output is very tiny.
The temperature control of material to be ground utilizes microprocessor to realize by the temperature restriction of presetting, thereby controls input speed by the driving of variable-ratio.
Size with mil scope of good relative scalar is provided with in following example.
