A new centrifugal atomization technique of spray rotation for powder preparation

摘要

A centrifugal atomization equipment of spray rotation with high pressure fluid as actuating medium was designed. Because high pressure fluid on one hand forms fluid kinetic pressure lubrication at ro- tary pair, on the other hand drives rotary plate rotate at high speed when spraying at high speed from the ends of hollow leaves of leaf-type rotary plate, the rotary speed of the plate is up to 30 000r/min, not only increases the fine powder ration of equipment, but also the equipment possesses the characteristics of low noise, pollution- free, easy starting, stepless speed regulation, convenient controlling and so on.
