The rotary dryer, a reliable and low-main-tenance machine for high throughput rates, can handle even materials with difficult properties. Whether installed as a stand-alone unit or in conjunction with other machines, rotary dryers are ideal for drying – and optionally for preheating/pretreating fine-grained and lumpy materials. They can

A rotary dryer is a device that uses rotation, gravity and warm gasses to dry a material. These driers range from small clothes dryers to large industrial systems. Regardless of their size, the majority of rotary dryers work the same way. A drum rotates and moves material while hot gasses quickly dry it out.
