Description
Technical field
The utility model relates to a kind of nano level superfine milling apparatus, specifically, relates to a kind of high-effect stirring-type nanon ball-mill.
Background technology
By micron order, submicron order ceramic slurry, being worked into nanoscale is further when previous more difficult problem, domestic relevant research mostly adopts agitating ball mill and sand mill to carry out testing and small lot batch manufacture, but be all limited by that the efficiency of grinding own is low, cost is high, cannot produce in batches, and because which limit the application of nano material on pottery.This case proposes and optimizes the motion model of the high-effect grinding of nanopowder, and accordingly to Ball-stirring mill mill type modification, provides the apparatus and process technology of a set of high-efficient grinding nanometer scale ceramics powder.
The difference of agitating ball mill and ball mill is the agitator in agitating ball mill, with the form of rotating, kinetic energy is passed to abrasive media and input energy fully to make to obtain between abrasive media, thus make the material be polished more easily reach desired smashing fineness.The abrasive action of agitating ball mill can be determined by the shearing force of abrasive media (mill ball).The motion of abrasive media is mainly divided into the movement of peripheral direction laminar flow part and radial direction to circulate the movement of part.The motion of abrasive media is arranged by the translational speed of frotton (dish), and with barrel type shape and grind that Jie measures number relevant.
The factor affecting the grinding usefulness E η of nanometer slurry mainly contains: radial velocity ν, radial velocity gradient d ν θ/dr, vertical speed ν Z, vertical speed gradient d ν Z/dz, mixing drum effective volume V, mill Jie diameter of phi, mill Jie density p m, pulp viscosities exponent gamma, material new surface energy coefficient τ s.
Nano-grinding process is no longer an independent physical process, but one based on abrading-ball motion, and whole system is closely related the complex process of Coupled motion, even also includes the generation of many physical-chemical reactions.Grinding efficiency can not the size of the input of alone energy again be measured.This case proposes to take factor as the leading factor to grind usefulness, and have found the other factors relevant to it.Because Physical grinding nano-powder there is no the successful case of large-scale production before this case, the mathematical relationship of the description that we cannot be quantitative between them.The method that this case adopts is, under the relatively-stationary condition of its dependent variable, finds a certain variable and the relation of grinding usefulness E η, until find the high-effect optimal value completing each parameter being ground to nano-powder task from micro-powder by experiment with theory analysis.
Agitating ball mill is the capital equipment of ultra-fine grinding industry for a long time always, and it has, and structure is simple, grinding efficiency advantages of higher.But in the grinding of nano material, due to defects such as its rotating speed are low, and abrading-ball shape of movement is single, and velocity gradient is little, granularity more fine lapping usefulness is lower.Because which limit its application in nanoprocessing industry.Also counteracts that nanometer technology applying at ceramic industry.
