A classification system is composed of a classifier, a dust collector and a draft fan. The material suction force under the action of the fan by the lower inlet classifier with the updraft speed to the classification area, strong centrifugal force generated in the high-speed rotation of the turbine grade, the thickness of material separation, meeting the size requirement of fine particles by classifying blade gap into the cyclone separator or dust collection, disappear the speed of the coarse particles entrained fine particles hit the wall, along the cylinder wall decreased to two times after two times the wind outlet, strong washing effect, the particle separation of fine particles up to two grade grade area, coarse particles down to the discharging port at discharge.
1, without water, washing, completely dry production, can obtain a narrower particle size distribution and pollution free abrasive powder; a classification according to the current domestic and foreign standard processing into any brand (such as: GB W63 ~ W3.5, Japanese standard 240#~3000， European standard F230/53 ~ F1200/3). Single rate of finished products reached more than 75%.
2, high classification accuracy, cutting particle size more accurate, lower speed required, long service life.
3, independent casting bearing seat, never deformation, long service life.
4，the optimized transmission design, the axle bears the force small, the service life is long.
5, unique pipeline design, to help powder flow, and help to reduce wear and tear, easy to wear parts, easy to change and deal with.
6, the company unique frequency conversion feeding system, to help the dispersion of materials, can guarantee the continuous, uniform and stable feeding, to help product particle size control.
7, unique internal circulation, two times wind design, classification cone gap adjustable, gas consumption greatly reduced, so that classification energy consumption reduced, fine powder extraction thoroughly.
8, the separation of the flow path will help to reduce the wear of the bottom of the grading wheel, and more conducive to the control of large particles.
9, closed vacuum operation, no dust pollution.
10, stability is good, once adjusted fixed parameters, can be stable production;
11, especially the extraction of fine powder more thoroughly, good stability, this core competitive advantage has been widely recognized by the industry.
12，the whole system adopts automatic control, which can realize one button type start and stop. The operation is simple and convenient, and the central control connection can realize remote control.
ZJ-F series precision air classification function that cannot be classified in the general classification sorting equipment for the material, especially suitable for processing strict restrictions and requirements of maximum particle size distribution is confined, such as calcium carbonate, kaolin, talc powder, barite powder, copier toner and coatings, mica, graphite, auxin, aluminum hydroxide.
The ZJ-F series precision air flow classification function can satisfy the requirements of grain size and particle size distribution of materials which are very strict with the impurities content or are extremely sensitive to iron. Typical materials are phosphors, titanium dioxide, starch, silica gel, aluminum, copper, phosphors and various high-purity pigments.
Abrasives and hard materials
ZJ-F series precision air flow classification function, superfine classification, Mohs hardness of seven or more rigid materials, vertical turbine classifier applications, so that equipment wear minimal. The speed of the grading wheel can be adjusted, and the crushing parameters can be optimized. After the combination of the multiple classifiers, a narrow grading of several particle size segments can be completed at one time. Typical products are: diamond, silicon carbide, boron carbide, tungsten carbide, special ceramics, Emery and so on.
Food, health care products, medicine
ZJ-F series precision air classification function of fine processing of food and medicine and health care products, the characteristics of low temperature crushing, high purity and fine finish and easy to clean, make the ZJ-F series ideal for pharmaceutical, health care products and food industry, not only improves the bioavailability and efficacy of the drug, and reduce production cost. Typical products are: pollen, hawthorn, letinous edodes, pearl powder, stomach medicine, nimodipine, antibiotics, contrast drugs, Ganoderma lucidum, Chinese gallnut, Polygonum multiflorum and so on.
ZJ-F series precision air classifier can be classified into inert gas under closed circuit system, and the items which are easy to burn, oxidize and explode can be classified. Such as carbonyl iron powder, nickel powder, tungsten cobalt alloy powder and fine powder etc.
Note: only a partial list of types of equipment in the box above, our company can be a multistage classification device can be a product of a multistage classification equipment for scientific combination according to the actual needs of users, such as ZJF series precision air classifier can one-time 1-5 standard products.
