Alumina gas calciner

Smaller footprint Flexible operating fuels Cost-effective No moving components One source supplier Our calciner aims to offer a more productive experience At FLSmidth, we understand how important it is to have a gas suspension calcination system that provides optimal performance while also being able to maintain economic benefits. That’s why we offer you our Gas Suspension Calciner, a system designed to be affordable and provide the most productive experience available. As a world leader in gas suspension technologies, we have been supplying these systems since the 1970s. They are responsible for processing fine materials, such as potash, phosphate, limestone fines, alumina, trona, clays, talc and other mineral products. We have designed units that have a processing capacity between one tonne per hour and 800 tonnes per hour, making them highly desirable pieces of machinery. They are stationary vessels with few moving parts, no rotating grid plates, and a simple PID control of the fuel. In this particular system, fuel is combusted in an external air heater, and fine ore is made sure to be in direct contact with hot gases produced by it. The material is immediately incorporated in the hot gases and dried in seconds. Dry ore and spent gas are then separated in a cyclone, which results in the refined product.
