Rotary Calciners

Rotary Calciners are used to calcine materials at high temperature. The rotary calciner comprises of rotating shell, rollers or tyres, combustion chamber, stationary hood, screw conveyor and many more tools. The rotating shell is supported on rollers and a suitable drive arrangement is provided. The internals are suitably refractory lined to minimize the heat losses. The combustion chamber produces hot gases which are required for calcination. This combustion chamber is connected to stationary hood and the feed material is fed at the controlled rate. The calcined material flow in counter current fashion within the calciner and gets discharged through discharge hood.
