We also include within this group the attapulgites, sepiolites and bentonites. Main applications of this family of materials are the Ceramics Industry, Absorbents Industry of several types, Refractory Industry and Paper Industry, a bit less in plastics, paint, etc
To prepare the clays for later operations, ANIVI recommends Roller Mill technology, ideal for semihard and non abrasive minerals. The Mill is provided with a High Efficiency Dynamic Classifier, by which we can change the particle size without stopping the plant and from the control panel. These plants are designed to let add a simultaneous drying, in those cases when the product moisture content so requires it, making in this way the production costs sensibly lower.
ANIVI also offers dryers when the supply conditions demand a drying of the final product or in an intermediate stage of the process.
Calcining is one of the operations to improve clays and kaolins features. ANIVI can offer rotary kilns for chamottes production or kaolin calcinations to generate materials with low LOI or losses of ignition. The productions obtained make these plants economically feasible.
