Description
Technical field
The present invention relates to technology of chemical engineering, Chemical Reaction Engineering and technical field of powdered material preparation, and in particular to one
Kind ball milling reactor more particularly to a kind of microwave-assisted planetary type ball-milling reactor.
Background technique
Ball milling is using the percussion of abrasive body and the abrasive action of abrasive body and ball milling inner wall and by crushing material
And mixed process.When the rotation of ball-milling reaction device, due to the rubbing action between abrasive body and ball milling inner wall, by abrasive body according to
The direction of rotation is fallen again after taking, and is crushed material continuously.High energy ball
Mill is the high-speed rotation or vibration using ball milling, so that hard sphere is carried out strong shock, grinding and stirring to raw material, powder
Crush the method for nano-scale particle.Ball grinding technique can be also used for the machinery of powder other than comminuting matter, mixed material
Alloying, this be it is a kind of so that powder is subjected to deformation repeatedly, cold welding, broken by high-energy ball milling, to reach atom between element
The complicated physical and chemical process of horizontal alloying.As it can be seen that ball grinding technique is very widely used in the industrial production.
Mechanical milling process is a dynamic process, liquid can be made to consolidate, it is solid between strong collision occurs, to generate part
High temperature can produce high temperature and high pressure environment if providing heating environment simultaneously, promotes the diffusion of atom, is conducive to mechanical alloy
Change, but since traditional heating process is to transmit energy by heat transfer and convective heat transfer, mechanical alloying process is slow
Slowly, it usually needs tens hours or even a hour up to a hundred, low efficiency, this process is in addition to rate of energy transfer and energy benefit
With rate it is low except, due to being the heat transfer of contact, so design structure also can be extremely complex.
Planetary ball mill is designed for powders such as crushing, grinding, dispersed metal, nonmetallic, organic, Chinese herbal medicines
, it is particularly suitable for laboratory research and uses, its working principle is that is rolled at a high speed in grinding pot using abrasive material and sample, to material
Strong shear is generated, impacted, rolled and achieve the purpose that crushing, grinding, dispersion, emulsifying material.Planetary ball mill is at same turn
There are four ball grinders for dress on disk, and when turntable rotation, ball grinder surrounds Pivot Point Center rotation again while revolving around turntable shaft,
Make planetary motion.Abrading-ball mutually collides in high-speed motion in tank, grinds and mix sample.The product can be used dry, two kinds wet
The product that method grinding is different with combination grain, material is different, abrasive product minimum particle size can be to 0.1 micron.It can be real well
Existing various technological parameter requirements, simultaneously because being school, research unit, company the advantages of its small lot, low-power consumption, low price
It is the preferred unit for carrying out disintegrating process, new material, coating and studying.
It is well known that microwave heating is the energy feature using microwave, the process heated to object.Microwave is frequency
In 300 megahertzs of electromagnetic waves to 300 gigahertzs.Hydrone in heated medium material is polar molecule, it is quickly changing
High-frequency electromagnetic field action under, polarity orientation will change with the variation of external electric field, causes the movement of molecule and mutually rubs
Wipe effect.The field energy of microwave field is converted into the thermal energy in medium at this time, increases temperature of charge, generates thermalization and extruding is a series of
Materializing procedure and achieve the purpose that micro-wave drying.Microwave is instantaneous heat temperature raising to dielectric material, therefore has and quickly add
The feature of heat.On the other hand, the output power of microwave is adjustable at any time, medium temperature rise can inertialess change correspondingly, there is no " remaining
Heat " phenomenon, the needs of be highly advantageous to automatic control and continuous production.
