PRETREATMENT DRUM & HEATING is a piece of equipment used in industrial production to pretreat raw materials. It usually consists of a rotating pretreatment barrel and a heating system. During the operation, the raw materials are put into the rotating pre-treatment barrel and heated by the heating system. This helps change the physical or chemical properties of the raw material, making it easier to handle during subsequent production processes. This kind of equipment is usually used in chemical, food processing, pharmaceutical and other industries to improve production efficiency and product quality.
