Description
Technical field
The present invention relates to powder and the industrial equipment field of the nano-milled technology of wet method, specifically superfine powder slurry
The efficient centrifugal piece-rate system of nanometer sand mill.
Background technology
Sand mill since the advent of the world has won in material fine field scientific research person, corporate boss due to haveing excellent performance
Good reputation, with new energy, the rapidly increasing of new material market demand, the requirement to its performance and quality is also increasingly stringent, special
It is not that the developed countries such as America and Europe have tightened up requirement.The wet grinding that group of Germany is strangled from the last century nineties by China
Technology successfully introduces the country.
Sand mill is also known as ball mill, is mainly used for the wet grinding of chemical liquid product, can substantially be divided according to performance
For vertical grinding machine, horizontal sand mill, basket type sand mill, stick pin nanometer sand mill etc..It main application field can be with 2000
Year is diacritical point.With the promotion of people's living standard, the light of 3C Product, thin, short and smallization and nanometer fineness material are white using it
How ultra-fine grinding techniques are applied to the making of nano material and disperse to grind the important topic become instantly by thermalization,
Before 2000, how business circles problem encountered is improves dispersion grinding efficiency to reduce labour costs, such as Ran Liao ﹑ oxygen
The industries such as Hua Gao ﹑ Gui Suan Gao ﹑ Tu Liao ﹑ paint, You Mo ﹑ pencils, food.And after 2000, how industrial technology bottleneck is then
Obtain miniaturization（Nanosizing）Material and how nanosizing material is distributed in final products, such as photoelectricity industry TFTLCD ﹑ Jet
Na meters of Cai Liao ﹑ electricity Chan Ye ﹑ Guang electricity Chan Ye ﹑ medicine of ink ﹑ Ci Cai Liao ﹑ Bao Jian Pin ﹑ bio-pharmaceuticals and Xi born of the same parents' Po Sui ﹑ Yangization Wu ﹑
Biochemical Chan Ye ﹑ chemical fibres Chan Ye ﹑ building materials Chan Ye ﹑ metal Chan Ye ﹑ soap, leather, electronic ceramics, electrocondution slurry, offset ink, weaving
Product, bio-pharmaceuticals, painting printing ink, chip polishing fluid, clasmatosis, cosmetics, ink-jet ink, ceramic ink jet, new energy battery
The industrial circles such as material, metal nano material, plastic material, extraordinary nanometer aeronautical material.
Existing lapping mode mainly has two kinds of dry and wet, and the operation principle of wet grinding sand mill is using stirring
Lapping mode, adds in abrasive media ball in closed grinding chamber before starting to work, material to be processed is mixed in advance with water
Liquid slurry is delivered to grinding chamber by circulating pump, and during rotor high speed rotation, when driving the movement of abrasive media ball, drive is referred to as
The abrasive media and grinding charge of " ball "（Slurry）Eddy motion is done, makes abrasive media under the influence of centrifugal force along inner tube wall under
It moves upwards, redrops and under the effect of gravity when reaching liquid level.It realizes to solid particle in solid-liquid phase mixture
Crushing, reciprocating extrusion, grinding, collision between rotor and its stick pin and mill ball and solid-liquid phase mixed material in this course of work
Powder, generates strong collision, friction, extruding, shear action, milled solid particle, and discharging tube end is fixed with piece-rate system
Strainer, the guarantee of piece-rate system mesh size, which is ground material, to be passed through, and mill ball cannot pass through, and then pass through piece-rate system
Grinding material and abrasive media are realized into separation, so as to play the role of refining material.Material is flowed into from feed pipe, by closing
Working chamber is acted on rotor, mill ball, is flowed out from discharge nozzle, and work is carried out continuously.Existing sand mill discharging piece-rate system sieve
Using clearance-type piece-rate system, be directly separated material and abrasive media, not only separating effect is poor, but also separative efficiency compared with
It is low.Most of cylinder or drum is round, and there are two types of the sieve pore formed between screen bars is general, its a kind of cross section is square
Shape, the sieve pore shortcoming of this sieve is that discharging is slow, and is easily blocked by the bulky grain in material or broken abrasive media；Separately
Its a kind of cross section is trapezoidal, and the sieve pore discharging of this sieve is fast, but shortcoming is easy to wear, sieve pore section is caused to become larger, material
Grain size is uncontrollable, and is susceptible to leakage abrasive media phenomenon, seriously affects product quality, therefore service life is short.
