Micronizers
Micronizer is a pulverizing machine which uses high-speed compressed air to grind dry-type materials into ultra fine powders. It consists of screw feeder, milling nozzle, milling chamber, classifier chamber, and etc.
In adjustable speed, screw feeder doses the raw materials stably and continuously into the jet mill. Compressed air reaches a very high speed when rushing through the special designed nozzles. Carried by the compressed air, materials crash in the midst of air flow, where they grind with each other by impacting repeatedly. The ground materials fly upwards with the rising air; entering the classifier chamber, where ground materials facing two forces – the centrifugal force result from the fast rotation of classifier wheel and the pneumatic attraction by the suction fan. If the ground materials are finer than grading range, pneumatic attraction is stronger, so materials pass through the classifier wheel and move on to the cyclone and dust collector to be collected. In contrast, coarser materials are rejected back to the milling chamber to be re-milled.
