Common mineral slags dried in rotary drum dryers include blast furnace slag, steel slag, copper slag, zinc slag, nickel slag, and phosphate slag. These are byproducts of smelting and refining operations that require drying before use in construction (slag cement, aggregate), road building, ceramic manufacturing, or further mineral processing. Moisture content in raw slag varies from 8–25% depending on quenching method used.
Mineral slags are highly abrasive due to their hardness and angular particle shapes, causing accelerated wear of drum shells, internal flights, inlet chutes, and discharge areas. Wear-resistant steel liners (e.g., hardox or manganese steel) are used on the drum interior and in areas of high product impact. Flight materials may require hardfacing or replacement with cast wear-resistant alloys. Regular thickness measurements guide planned maintenance and liner replacement schedules.
Mineral slag rotary dryers can operate at inlet gas temperatures of 400–800°C for highly moisture-laden or large-throughput applications. The slag itself can tolerate very high temperatures, but care must be taken in dryer design to ensure the structural integrity of the drum shell at elevated temperatures. Refractory-lined inlet sections protect the drum from hot gas erosion and allow operation at higher inlet temperatures.
GGBFS used in cement production must meet strict quality standards, including moisture content below 1% before grinding. Rotary dryers used in slag cement plants must reliably achieve this very low outlet moisture while handling the large volumes (100+ tonnes per hour) required by cement grinding mills. Precise outlet temperature control and real-time moisture measurement at the dryer outlet are essential to maintain consistent GGBFS quality.
Slag rotary dryers require high-efficiency dust collection because fine slag particles (especially silica-containing slags) present both respirable dust and particulate emission concerns. Cyclone pre-separators capture coarse particles for product recovery, followed by bag filters with pulse-jet cleaning. For slags with very fine particle fractions, wet scrubbers may supplement or replace bag filters. Enclosed material handling systems (covered conveyors, enclosed storage) complete the dust control program.
Mineral slag drying benefits from high inlet temperature operation (to maximize evaporation rate per unit drum volume), exhaust gas heat recovery using air-to-air heat exchangers to preheat combustion air (increasing burner efficiency), and optimization of drum inclination and rotation speed to maximize flight cascade pattern efficiency. Since slag has no fire risk at elevated temperatures, higher-temperature direct-fired operation is fully acceptable and thermally advantageous.
