In conjunction with our affiliate companies Louisville Dryer Company, Vulcan Ironworks, and Industrial Kiln & Dryer, Stansteel has built over 5,000 rotary heating, drying, cooling and mixing devices in over the last 100+ years. It is without question one of the most critical and important pieces of machinery on any hotmix asphalt plant. In evaluating the specific customer requirements, whether it’s on a high production counterflow drum mixer, a batch plant or a rotary device that is attached to some other equipment, it is mandatory that a number of factors have to be taken into consideration for the proper engineering design, the application know-how, and the precision fabrication of both the internals and the externals.
Please remember that an average rotating drying unit on most asphalt plants will experience over 1,000,000 revolutions in a year. The revolving process of this heavy piece of machinery with varying loads of materials, with varying temperatures and conditions, needs to be well thought out, well engineered in order to give an acceptable service and life cycle. We do not recommend or manufacture throw-away type drying units. Whether it is a replacement shell, an all-new counterflow dryer or one of the highest production drum mixing plants on the market today, we study and evaluate the conditions and build extremely heavy duty and rugged components throughout.
In looking at the externals of the heating and drying units, we evaluate the following items:
