Bentonite dryer equipment is suitable for rapid drying of mineral soil such as bentonite, kaolin, bauxite, diatomaceous earth, clay, pottery clay, yellow mud, etc. Demand design, using high temperature hot air drying process, the moisture content of the dried material is less than 5%, and the dry and wet are even. Use drum to dry mineral materials such as bentonite, high heat utilization rate, large daily processing capacity, simple operation, low maintenance cost and durable.

Working principle of bentonite dryer

The bentonite drying system is mainly composed of hot air stove, feeding conveyor, rotary drum, discharging conveyor, induced draft fan, cyclone dust collector, bag filter (or wet dust collector) and operation control system. The equipment adopts a downstream drying process, and its working principle is as follows: After the bentonite enters the drying drum, it is divided into the following working areas: one is the material guide area, where the bentonite enters this area and contacts with high-temperature hot air to quickly evaporate water, and the bentonite guides the material at a large guide angle. The plate moves and is introduced into the next working area; the second is the copying plate area, where the bentonite is lifted by the copying plate to form a material curtain state. At this time, the bentonite is in full contact with the hot air, and the water in the bentonite quickly evaporates and peels off to become water vapor. , the water vapor is immediately drawn away by the induced draft fan, so as to achieve the purpose of drying the bentonite; the bentonite is dried in this area into a loose state with a moisture content of less than 5% (or lower), and after heat exchange, the bentonite reaches the required moisture state. Enter the discharge area at the back; the third is the discharge area, where the drum does not have a lifting board, and the bentonite rolls and slides to the discharge port in this area to complete the entire drying process.
