Cooling of high-temperature bulk materials (up to 1,400°C) of all kinds in an indirect water cooled rotary tube. Extremely high throughputs are handled safely and reliably.

Cooling of hot, free-flowing bulk materials (up to 1,200°C) in a water cooled tube-bundle heat exchanger. Highest throughputs are handled in a very compact apparatus.

Cooling of high-temperature bulk materials (up to 1,000°C) of all kinds in an indirect air cooled rotary tube. Using the dust-free 200 – 300°C cooling air can save up to 15% primary energy in firing systems.

System solutions for the production of highest grade polyphosphates (as additives for detergents and foodstuffs) of all particle sizes, bulk densities and phase compositions that are in demand on the market.
