Rotary Kilns

The direct fired rotary kiln is used in chemical and mineral industries for partial or complete splitting off and evaporating combined water from hydrates and crystalline products and in the heat treatment of various substances with the purpose of changing their molecule or chemical composition. NSI Equipments, an established ISO 9001-2000 certified company, supplies rotary kiln systems to perform either endothermic (heat absorbing) or exothermic (heat liberating) processes. The company has designed systems to operate in either parallel flow or counter current flow configuration. It has supplied rotary kiln units for mineral processes, such as calcining, roasting and to various applications up to 2500 mm ID x 44 mtr length; and also specially designed rotary kilns with product discharge through cooling coil fitted over the shell for to process activated carbon. Sealing arrangement at both ends are essential to prevent ambient air from entering the process and air leakage can have varying effects on different
