发明名称 Controlled conversion of minerals to pigmenting elements systems and methods
摘要 The present invention may provide talc calciner systems and methods to produce better and more efficient products by engineering a* and b* values for calcinated products perhaps by processing low iron talc in an indirectly heated, multiple zoned calciner which may progressively heat the feed supply at perhaps specifics residence times to produce a desired product.

主权项 1. A method of talc calcination comprising the steps of: milling low iron talc to provide a feed supply; inputting said feed supply into a multiple zoned calciner comprising a calciner tube having at least one alloy; indirect variably heating at least three zones of said multiple zoned calciner resulting in a product; processing said feed supply in said at least three zones of said multiple zoned calciner; cooling said product; and outputting said product.
