Key Benefits

  • High thermal efficiency
  • Gentle treatment of feed material
  • Low maintenance and operating costs
  • Low wear

Highly thermal efficient Wet Ball Dryer

Refractory manufacturers must deliver the ultimate in product quality, but at a financial and environmental cost they can afford. The high thermal efficiency of the Pyroprocessing Shaft Dryer delivers on all fronts, making it a machine that is fit for the future.

The needs of the refractory industry are at the heart of the design of the Pyroprocessing Shaft Dryer, which offers unprecedented efficiency for drying material pellets such as aluminum oxide or spinel.


This unique pellet dryer enables you to reduce the moisture content of pellets or briquettes to a level acceptable for furnace charging. Efficiency is gained through the highly effective heat exchange and the generation of only a small amount of fine dust. The latter not only improves efficiency, but also ensures maintenance and wear stay low. Furthermore, our Wet Ball Dryer offers very quiet operations, even when process exhaust gases are used.

Boost your drying with our future-ready Pyroprocessing Shaft Dryer

Developed in close cooperation with the refractory industry, the Pyroprocessing Shaft Dryer delivers exactly the performance you need for efficient and sustainable operations.

A Wet Ball Dryer with unique features

Our Pyroprocessing Shaft Dryer operates according to the counter flow principle. It is specifically designed to reduce the moisture content of pellets or briquettes to a level acceptable for the kiln feed. Its unique design enables efficient heat exchange and generates only a small volume of fines, thus improving the overall plant efficiency.

How does a pyroprocessing shaft dryer work?


Preheated air (e.g. 300 °C) reaches the upper as well as the lower part by means of a drying air fan. In the upper section, the hot gas enters the chamber and flows through a bundle of pipes from top to bottom. The pipes warm up and contribute to the drying process. To reach the required heat, the drying air is heated to a constant and controlled drying temperature by using an air heater.

 

In the lower section, a cross construction and an arrangement of gas entry and exit cones ensure the distribution of the hot gas, which passes through the material in counter flow. The dried material is discharged through a cone into a tube, which empties into a vibrating feeder.
