Utilizing Rotary kilns as the key pyro processing equipment, HANDA has experience with over 80 different types of ores, minerals, chemicals and wastes. Some of the materials calcined, roasted, nodulized, burning or otherwise processed in rotary kilns are: cement clinker, limestone, magnesite, dolomite, fire clay, blast furnace dust, sludge, lightweight aggregate, petroleum coke, zinc minerals, calcium carbonate waste, gold ores, paint pigments, lead minerals, catalysts, etc. Applications for rotary kilns continue to grow to meet new processing needs. When unproven process are required or calcinations of unusual materials are desired, HANDA offers batch and pilot scale kilns that can simulate conditions in continuous commercial rotary kilns, allowing our customers to test small samples of material under various process conditions, as well as part of a continuous process.
