Molybdenum Concentrate Dryer-Dongding Drying Equipment

Molybdenum Concentrate Dryer Machine Working Principle Firstly, wet material is crushed by the crushing machine, then transported to the rotary drum dryer bythe belt conveyor. Because of the inclination of drum dryer, material with hot air moves to the end of dryer body, during which process wet material gets fully contact with the hot air. After drying, most of the dry material is
