Introduction to Rotary dryer A rotary dryer is an industrial dryer that is used to dry material by eliminating or reducing the moisture content. Its basic components include a rotary body, raw material feeding plate, driving mechanism, supporting devices, among others. The raw material plate is arranged conveniently to allow adjustable angle positions. The material to be dried is inserted to the rotary cylinder through the raw material plate. Hot air flows within the cylinder causing the separation of water from the material by converting it into vapor which is discharged into the atmosphere. At this point, the material becomes dry. Rotary dryers are widely used in drying of a variety of materials such as slag, clay, sand, limestone, cement, chemicals, animal feed, fertilizers, human food, etc. They’re very popular among construction industry, chemical industry, fertilizer industry, recycling industry, metallurgical industry, just to name a few. Its advantages include but are not limited to the following: a high capacity for drying material, high output capability, its low energy consumption (is economical), smooth rotation, and ease of operation.
