Process selection
1.Continuous coating process
A.”Double-power Pin disc grinding + Deagglomeration machine” continuous coating process (popular application in European and American well-known mineral companies).
B.Three-roller Mill continuous coating process(mature technology, low investment, suitable for powder coating with stearic acid; self-friction heat generation, less auxiliary equipment; suitable for coating the powder of 325~1250 mesh).
C.Turbo Mill (tower type mill) continuous coating process(Simple process, popular in Chinese mineral companies).
2.Batch coating process
High-speed mixer + Classifier/Deagglomeration machine”(Intermittent operation; coating time and temperature can be adjustable; good adaptability to different modifiers and formula; suitable for surface chemical coating of small and medium batch powders.).
3.Compound coating process
Suitable for more complicated coating requirements.
