Sepax vortex classifier fully absorbs the technical advantages of FSN vortex classifier and rotor classifier, breaks through the "secondary separation" theory of conventional classifier, and successfully realizes the crushing of materials.
"One into three" is a new generation of efficient classifiers.
⑵
The inverted cone classification ring of the rotor classifier is changed into a cylindrical classification ring with a horizontal partition, and a circle of wind guide blades is added around it, so that the inertia force of the same mass particles at any position on the surface of the cylindrical classification ring and the moving distance from the rotor surface to the shell are unchanged, and the classification accuracy and stability are improved, and the classification accuracy of particles below 45μm is as high as 95%.
⑵
Compared with FSN vortex classifier, Sepax vortex classifier is equipped with dispersion and pre-classification devices. Aerodynamic analysis method is used to optimize the whole flow field. Adopt suspension dispersion technology to fully disperse materials; Pre-classification technology effectively reduces the interference between large and small particles and creates conditions for accurate classification.
⑷
Compared with centrifugal classifier, cyclone classifier and single (double) rotor classifier with similar size, Sepax vortex classifier has the advantage of large processing capacity, so it can better meet the needs of mass production. The advanced and reasonable structure makes the air volume, output and powder feeding rate of the classifier change in a wide range without affecting the efficiency of powder selection, and the classification performance is stable and reliable.
⑸
Wear-resistant materials or wear-resistant technologies are used to treat the vulnerable parts of classifier, such as distributor, spiral angle of cyclone, wind guide blade, rotor blade, fan impeller, etc., and the wear rate is extremely low, which effectively prolongs its service life.
⑹
A new design scheme is adopted for the bearing seal under the spindle, and a dry oil station is used for forced lubrication of the bearing, which effectively solves the two major problems of ash ingress and oil leakage of the bearing and effectively prolongs the service life of the bearing.
⑺
An efficient dust removal system can collect a large number of particles below 30μm into the finished product in time, effectively improving the specific surface area of the product.
