The patented dry cleaning drum System Mozer® TRH replaces the use of rock washing equipment in the preparation of limestone
The customer
- Internationally operating customers in the stone and earth industries.
The challenge
- During the extraction of limestone, a so-called pre-screening debris often accumulates, which consists of up to 90 percent good limestone, but is frequently very heavily contaminated with clay or loam.
- Without appropriate cleaning, the limestone can only be sold as an inferior product.
- To clean the impurities on the limestone, rock washing plants have often been used to date, followed by a further process to dry it.
- The use of rock washing plants is associated with considerable investment and energy requirements and, moreover, cannot be operated in a technically and economically viable manner during severe frost or in areas where water is scarce.
The solution
- The patented dry-cleaning drum System Mozer® TRH combines the process steps of drying and cleaning and thus replaces the use of rock washing plants.
- After pre-drying the rock in the first section of the dryer, clay and loam components adhering to the limestone are removed in the second section by a targeted combination of residence time and mechanical stress.
The result
- As a result, the TRH dry cleaning drum is characterized by very good cleaning results.
- The process is also convincing due to its particularly efficient mode of operation and moderate investment and operating costs.
- Allgaier Process Technology also offers solutions for the downstream process steps of screening and sorting with the MSizer and MSort from Mogensen.
