Grinding, micronising and classifying have always been common processes in pharmaceutical industry.The demand in particle fineness changed dramatically over last years.
Spiral Jet Mills are characterized by their simple operation and excellent cleaning possibilities into which into.Compressed gas is fed into the distribution ring surrounding the grinding chamber.The gas enters the grinding chamber at high speed through the tangential nozzles fitted to the distribution ring and causes the feed material in the grinding chamber to rotate.The rotating ring of feed material thus forms into which particles are constantly drawn.
Working Principle:
- The Powder Particles are accelerated in spiral movement inside the milling chamber by number of angular holes in a ring and placed around the periphery of the chamber. Air jet Mill easily micronizes the heat sensitive and low melting point materials
- Jet mills do not have any moving parts, thus the chances of contamination due to contact with grinding media is eliminated. It’s an ideal process to grind material that are heat- sensitive and sticky as no additional heat is generated. It works solely on fluid energy
To prevent coarser particles from flooding through
