Crushing material and grinding are the important contents of powder technology, and it is widely used in the every field of national economy, and material modification processing can be optimized material property or realize specific function.The Morphological control of material particles is the processing process contoured surface of particle being had to expection object, to realize the specific function of particle monomer or entirety, is the intermediate link improving the final performance of some product.Relative spheroidization can improve tap density, the packed density and mobility etc. of powder, spheroidization as cement flour particle can improve cement performance, metal ink spheroidizing of particles can increase reflectance, improve printing quality, the copper powder of spheroidization, graphite, glass putty show superiority in its specific application.
Crushing material, powder surface shaping or Morphological control have number of ways, machinery conventional cosmetic method usually adopt roll, rolling, ball milling, vibration (i.e. vibro-grinding) mode.Rolling is inserted by powder in a cannelure, and rolled heap powder-deposit around central axis by the circular pressure roller driven, roller is rolled over similar to it, and just material is by falling within eminence between two rollers, and bears two roller pressure.Rolling powder agglomerate is fallen into be parallel to each other and the roll shop building with certain interval is pulverized and shaping.Ball milling puts into drum after being mixed by a certain percentage by mill ball large and wear-resisting to powder and hardness, drum rotates along axle, mill ball in drum is elevated and is then fallen in staving rotary course, thus powder is impacted and makes stressed and friction mutually between particle.Vibration mode is similar to ball milling method, and distinguishing at vibration staving is move back and forth along single direction with certain frequency, thus makes mill ball carry out impacting to material and grind.Recent Ye You Tsing-Hua University patent, describes and a kind ofly adopts high-speed striking, the mode of shearing carries out spheroidization or Morphological control method and apparatus to powder.
No matter roll, rolling or vibration, ball milling, their limitation is: processed powder or there is in the effective processed stage part contacted with air with the mixture of abrasive media, namely there is the situation of open to the outside world or " fractional open ", at material by between action period, pressure or impulsive force can be discharged or part release.For the material of relative " softer " or " harder ", as having the metallic particles of toughness, because the absolute dynamics and controllability of processing process is limited, be difficult to the efficiency producing a desired effect and expect.In addition, all there is the separation problem of mill ball and processed powder in non-circulating type ball milling and vibro-grinding, and along with the continuous consumption of mill ball, processing intensity will change, this brings uncertainty to processing technology, in addition, also have and utilize centrifugal force to increase the grinding of processing dynamics, but the cost paid of so same existence and last obtain the high limitation of effect ratio.And noise problem, the energy consumption problem of wasting driving equipment body and mill ball to move all are difficult to overcome.In these defects, most importantly process controllability and energy consumption.
Summary of the invention
The object of the present invention is to provide a kind of apparatus and method with shaping of pulverizing, it is strong to the processing dynamics controllability of material, and processing intensity stabilization, efficiency is high.
For achieving the above object, the present invention is by the following technical solutions:

Detailed description of the invention
By reference to the accompanying drawings the present invention is described in further detail by the following examples.
As shown in Fig. 1 a-Fig. 1 c, this example show general principle of the present invention.
As shown in Figure 1a, adopt a perfect elasticity cavity if pulverize with apparatus for shaping, powder granule is wrapped in this flexible cavity.Original state, powder granule is only subject to being squeezed because of parcel power.Apply equal pressure up and down to this cavity, this flexible cavity will produce transverse horizontal distortion (even expanding), by the spherical elliposoidal become as shown in Figure 1 b.As illustrated in figure 1 c, when external force is removed, this flexible cavity returns to original form.The illustrated external force causing flexible cavity to be out of shape is pressure, but this external force is not limited to pressure, such as, also can be to make it deform to flexible cavity pulling force of exerting pressure.
In this cyclic process, in cavity, the powder granule of different parts will be subject to multi-faceted extruding; Meanwhile, due to Wall deformation (or volume also changes), extruding, friction will be produced between the adjacent powder granule be positioned at wherein because of relative movement, shear, although extruding has different from friction degree because being in the difference of cavity diverse location (A, B, C 3 point as in Fig. 1 a, 1b, 1c).Amplitude of deformation, speed etc. that the treatment effect of powder granule depends on outer elastic packaging power and causes by external force, and these can be controlled.
Simultaneously, flexible cavity offers at least one passage for entry/exit material while processing, make processing limit, limit can entry/exit material, this can get rid of rapidly the new material particles affecting efficiency adding and produce man-hour on the one hand in process, optimize shaping effect, improve working (machining) efficiency, continuous productive process or cycle operation continuously efficiently can be formed on the other hand, the material processed or part processes is delivered to outside cavity, other processing process can be implemented, and optionally the material after the extracorporeal treatment of chamber can be returned cavity by passage foldback again and process further.
Based on above-mentioned announcement, if meet the following conditions, then can be different from the embodiment of above-mentioned flexible cavity to implement the present invention:
