air classifier medicine fine chemicals reflective materials

WORKING PRINCIPLE

QLFW Classifier and feeder, cyclone separator, Dust Collector, induced draft fan, control system constitute a set of grading system. Material in the negative pressure under the action of the wind through the feeder quantitative rose to classification, rotating at high speed the classification of turbine under the action of the strong centrifugal force, the thickness of material separation, conform to the requirements of the particle size of the fine particles, through the classification of blade clearance into cyclone separator or dust collection, coarse particle entrainment of fine particles bump wall disappeared rate after, along the wall fell to a secondary tuyere, After the strong washing action of the secondary air, the fine particles are separated from the heart body, and the fine particles rise to the secondary classification of the grading area. The separated coarse particles are discharged through the known powder device.

PERFORMANCE FEATURE

It is suitable for fine grading of powder, especially for materials with light proportion. The particle size of the graded product can reach D95:5 ~150 microns. The particle size of the product can be adjusted continuously, and the variety replacement is extremely convenient.

◆ High classification efficiency (extraction rate)≥90%;

◆ Low speed, long service life, the same graded particle size, graded rotation speed than other horizontal, vertical classifier reduced by 50%. When producing the powder with hardness <5, the grading wheel has no wear; When producing Mohs hardness >7 powder, the service life of grading wheel is 5~8 times higher than other horizontal and vertical types;

◆ Vertical graded turbine device, low speed, wear resistance, low system power configuration

◆ Multi-stage classifier can be used in series to produce products with multiple granularity segments at the same time;

◆ It can be used in series with ball mill, vibration mill, Raymond mill and other grinding equipment to form a closed loop;

◆ System negative pressure production, no dust pollution, excellent environment, high degree of automation, strong stability, easy to operate.

◆ Food, medicine and health care products typical materials are: Lingdream spore powder, pollen, hawthorn, pearl powder, stomach medicine, nimodipine, antibiotics, contrast drugs, gallnut, polygonum multiflorum and so on;

◆ [Fine chemicals, ceramics, abrasions and refractorials] Typical materials are: garnet, silicon carbide, corundum, cerium oxide, alumina, boron carbide, tungsten carbide, emery, etc.

◆ [Magnetic powder, mobile phone electromagnetic powder, copy machine toner and electronic materials] Typical materials are: lead battery nickel-chromium battery, nickel-manganese battery, ferrite, manganese tetroxide, manganese dioxide, lithium cobalt, lithium manganate, carbon, etc.

◆ [Non-metallic ore and powder metallurgy] Typical materials are: quartz, barite, kaolinite, high calcium, talc, mica, graphite, wollastonite, etc.

◆ [Reflective materials, pigments, dyes and powder coatings] Typical materials are: iron oxide, titanium dioxide, glass beads, etc.

◆ Pesticide, feed and biological materials
