Dry cleaning of stone
"MOZER TRH system"
Drum dryers for simultaneous product cleaning have an area in the inside of the dryer in which the solid material is rubbed against itself to an increasing extent. Adhering dirt is removed by the coarse material and can be blown out with the dryer exhaust air.
The process replaces the complicated procedure of washing coarse minerals (especially limestone). Effective cleaning is achieved at low energy.
