Combined Drying and Cleaning TRH Efficient Treatment of Surface Contaminated Minerals with Combined Drying and Cleaning TRH Combined Drying/Cleaning drums from Allgaier are of single-shell design. This innovative drum design is a combined system in which the drying and cleaning of surface-contaminated minerals take place in a single unit. Therefore, only one drive and one bearing is required in each case. The plant is particularly suitable for the surface cleaning of coarse-grained, crushed rocks such as clay-contaminated limestone. Functionality: In the front section of the Combined Drying/Cleaning drum, the moist, surface-contaminated bulk material is dried very efficiently in co-current. A separate cleaning zone, enlarged in diameter, is located immediately behind the drying zone. Due to the special design of the internal internals in this area, the pre-dried, contaminated bulk material is intensively and dynamically mixed within itself. Benefits: High performance: No separate cleaning unit required due to combined design. Compact design: Compact dimensions and thus smaller footprint compared to wet cleaning. High efficiency: Minimal operating costs for the drying and cleaning preparation stages. Maximum efficieny: Cleaned rock material is already available in a dry state for further refinement. High safety: Frost-proof system, as no washing water and thus no water treatment are required.
