Bentonite dryer equipment is suitable for rapid drying of mineral soils such as bentonite, kaolin, bauxite, diatomaceous earth, clay, clay, yellow mud, etc. It adopts a single-cylinder dryer or a three-layer drum dryer structure, depending on the user Designed according to demand, using high-temperature hot air drying process, the moisture content of the dried materials is less than 5%, and the drying and wetting are even. The drum is used to dry bentonite and other mineral materials, which has high heat utilization rate, large daily processing capacity, simple operation, low maintenance cost and durability.
Working principle of bentonite drying equipment
The bentonite drying system is mainly composed of a hot air furnace, a feeding conveyor, a rotary drum, a discharging conveyor, an induced draft fan, a cyclone dust collector, a bag dust collector (or wet dust collector) and an 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: First, the guide area. The bentonite enters this area and contacts the high-temperature hot air to quickly evaporate the water. The bentonite is guided at a large guide angle. When the plate is moved, it is introduced into the next work area; the second is the plate copying area, where the bentonite is lifted up 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 into water vapor. , the water vapor is immediately removed by the induced draft fan, thereby achieving 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). After heat exchange, the bentonite reaches the required moisture state. Enter the discharging area at the back; the third is the discharging area. The drum does not have a copy plate in this area, and the bentonite rolls and slides in this area to the discharge port to complete the entire drying process.
Bentonite uses: drilling fluid, metallurgical industry pellet binder, molding sand binder, feed additives, cat litter, etc.
