Technical Field
[0001] This utility model relates to the field of powder processing technology, and in particular to an ultrafine powder microsphere sorting system. Background Technology
[0002] Fly ash is a multifunctional powdery mineral resource with significant market value. There are many methods for treating fly ash, among which sorting is an important means to improve its resource utilization. Sorted fly ash can be applied in multiple fields. Fly ash contains special microspheres, most of which are small, lightweight, smooth-surfaced, hollow spherical particles, called hollow microspheres or glass microspheres. Their main chemical components are oxides of iron, aluminum, and silicon, which constitute a large proportion of fly ash and are important products for advanced fly ash utilization. Microspheres can be classified into various forms according to their structural properties, each with its own unique properties. Therefore, it is necessary to design an ultrafine powder microsphere sorting system to sort the microspheres in fly ash, and then modify the sorted fine microsphere powder to improve its utilization value and apply it to more fields, thereby bringing good economic and social benefits.

[0027] The working principle of this utility model is as follows:
[0028] The materials in the raw material warehouse 101 are metered by the rotor scale feeder 102 and then conveyed to the primary classification buffer silo. From there, they are sent via powder feeding tank 108 to the primary vertical single rotor classifier 109 for primary classification. Powder with a particle size greater than 180 mesh is sent to the primary coarse powder silo 122.
