Drum Dryers Single-shell, double-shell and triple-shell drums Allgaier rotary drum dryers are used, primarily in the minerals industry, for drying free flowing, as well as sticky and abrasive, wet materials. Their main features are high throughput rates and the ability to process solid materials with widely differing grain sizes. The drum dryers are available in single-shell, double-shell and triple-shell versions and the design ensures high performance in a small space. Special versions also allow for the use of combined processes. Allgaier Rotary Dryers use proven flighting designs...

System RK/KT-R Single-shell drum with Screen - dries and screens materials such as aluminum scrap and shredded recycling products, therefore reducing the need for separate downstream screening steps. Single-shell drum with Cleaning Zone replaces separate washing steps for materials such as limestone aggregates, and also increases the amount of good material from dry separation. Two different models of indirect rotary drum coolers for hot bulk materials such as titanium dioxide, slag, hydroxides and gypsum, that provide for heat recovery from the hot products. This static, water-cooled sand...

Fluidized bed dryers and coolers Allgaier fluidized bed dryers can be used effectively for the treatment of materials such as sand, limestone, ceramics, pellets, granules, mineral fertilizers, salt and fine chemicals. The high rate of heat transfer in the fluidized bed ensures economical solutions and results in small plants. The dryers are extremely well-built and have no moving parts inside the process space. This results in minimal costs for maintenance and spare parts. Features • Low temperatures of the dried materials • Careful drying of sensitive products like granules and pellets •...
