WHAT IS A ROTARY DRYER ? Rotary dryer is one of the most widely used dryers that are used to dry various chemicals, minerals, food. These dryers are based on rotary ovens designed and upgraded by English Ransom in 1885. These dryers are composed of metal pipes with a diameter of 60 to 300 cm and a length of 6 to 24 meters, which are placed on rollers and rotate with a gentle slope around the horizontal ridge. Agricultural and vegetable wastes such as beet pulp, sugarcane pulp, tomato pulp and citrus peel are among the plant and agricultural materials that are used by rotary dryers to produce animal feed. In the chemical industry, rotary dryers are used to dry iron sulfate, manganese carbonate, zinc carbonate, zinc sulfate, etc. Also, in the production of asphalt, a rotary dryer is used to dry and heat the sand in the asphalt.
