Inquiry (采购产品): Rotary Kiln Dryers I am with US Bentonite, and we currently have 20, 30, and 50 ton dryers, diameters, 6',7', and 9' respectively. We will be using these dryers to dry bentonite @550 degrees, 60lbs in density. Can you provide any information as to the type burners we would use in conjunction with these dryers to obtain optimum results as to drying the bentonite in the most cost/energy efficient manner.
