20-Day Delivery and One-Year Warranty
Bentonite is a kind of clay rock, which often contains a small amount of illite, kaolinite, chlorite, zeolite, etc. Due to the changes of iron content, it is usually in white and pale-yellow color and easily become light gray, light green, pink, brown-red, etc. Aimed at the adsorptivity and other characteristics of bentonite, bentonite dryer is designed with large capacity. Zoneding bentonite drying technology adopts new grouped lifting blades equipment to improve the material filling rate and extend the stay time of wet bentonite in the cylinder. With improved production efficiency, Zoneding bentonite dryer machine is customized.
Through the drying treatment with bentonite drying equipment, the moisture content of bentonite can be reduced, thereby enhancing its stability and plasticity, making it more suitable for various industrial and agricultural applications. Bentonite exhibits excellent characteristics such as adsorption, gelling, and swelling. After bentonite drying, bentonite can be utilized as a binder, suspending agent, stabilizer, purifying and decolorizing agent, filling material, feed additive, catalyst, etc., and is widely employed in fields such as petroleum extraction, steel and iron casting, metallurgical pelletizing, chemical coatings, compound fertilizers, papermaking, water purification, pesticides, etc.
The bentonite dryer can be used for the rapid drying of various industrial clay materials such as bentonite, kaolin, and bauxite. It adopts a single-pass drying or triple-pass drum drying structure design and utilizes high-temperature hot air drying technology, resulting in the moisture content of the dried product being below 5%. Compared to other drying equipment, the bentonite dryer has a higher thermal utilization rate, large daily processing capacity, simple operation, low maintenance costs, and longer service life.
When bentonite drying machine is operated, the law of heat transformation and the effect of gravity play the main role. The drum is set at an angle of about 3-5。. Wet bentonite is conveyed into the higher end of the cylinder by feeding system and falls down into a screen, which favors the efficiency of heat transformation. When the drum rotating, bentonite is raised by the blades and falls. Here heat transformation between scorching wind and wet materials works best. Under the gravity, dried bentonite steps down to the lower end of the drum and is blenched out. In the gradual stepping down, the excessive liquid is removed. There equips a professional dust collector to collect waste gas.
