The main items of dust determination include dust concentration, particle size analysis of dust, analysis of free silica content, analysis of toxic dust content ( lead , chromium , arsenic , antimony , cyanide, mercury, etc.) and true density determination of dust.

The Centrifugal Coater is used for powder material's coating, such like pellet coating, film, enteric release, protective layer. slow releasing coating. coating and drying can be finished in one body, it has high repeatability of process, auto spraying of coating powder and the measure is accuracy, With compact action of centrifugal force, it can treat material with low density. The design and manufacture are inconformity with GMP. It is quick and full to clean and no cross pollution.
