Drying plant and technologies

Rotary drums are specially suitable to dry solid products such as raw materials coming from quarries (silca sand, limestone, clays, kaolin, etc.)
Several models are available, every drier is designed according to the specific material to be processed, requested throughput, moisture to be evaporated, available fuel.
Besides the rotary driers, Cimma supplies a wide range of drying-grinding systems.
Cimma’s engineering staff is ready for studying and solving client’s requirement for research and operation activity.
