Used Portable Rotary Dryers

A dryer is used for the evaporation of liquids from solids. Most types of dryers are indirectly heated with either an internal exchanger coil or an external heat transfer jacket. This allows the use of remote heating and cooling utilities such as water or oil to precisely control temperatures inside the dryer.

Direct-heated rotary dryer. 2. Indirect- Direct rotary dryer. 3. Indirect rotary dryer. 4. Special type. A rotary dryer is said to be of the direct type if, by virtue of its design, heat is added to or removed from the solids by direct exchange between the gas and solids. The direct heat dryers are the simplest and the most economical class.

May 10, 2007· ABSTRACT An investigation of the thermal drying of lignite has been carried out, by using an indirect heat pilot rotary drum. The process aims at the production of dry lignite and clean steam as part of a gasification procedure. Both flighted and bare drum modes have been employed. Temperature profiles along the dryer length, the amount of evaporation (moisture conversion) and the solids ...
