Coal feeder airlock feeders are used for feeding limestone lumps to raw mills, and coal lumps to coal mills in the cement industry to avoid false air entering into the mill thereby decreasing its efficiency. It is designed to pass hot air through the rotor pockets to reduce moisture in the material, thereby avoiding clogging of material in the rotor pockets.Coal feeder thus helps maintain the capacity.

Rotary Airlock Valves, often referred as Rotary Airlock/ Rotary Valves, are a type of rotary feeders which are used in a wide range of applications in process industries where there is a need to minimize system air losses while transferring material between vessels with different pressures. These are employed to regulate the material flow from one chamber to another while maintaining a good airlock condition.
They are used to maintain pressure and provide an optimal airlock seal between different product conveying transitions, such as gravity to pneumatic conveying lines. An optimal airlock condition is essential to prevent air pressure loss in high pressure and high temperature conveying systems. Besides this, they are employed to regulate feeding and metering functionality of a standard feeder.
