rotary kiln cooling down

The most common setting in which a cooler is required is when the product needs to be handled immediately after processing in the kiln. Material exiting a rotary kiln can range in temperature anywhere from 100⁰C to 1500⁰C, which is often too hot for subsequent handling and could risk damaging equipment. Cooling the material exiting the kiln

    Rotary Kiln Refractory: Preventative Care

    Each time the rotary kiln is heated, the refractory expands with the drum. As the kiln cools down, the refractory retracts. If a kiln is constantly being heated up and shut down, the refractory can easily become stressed, causing cracks. Similarly, cracks can also occur from heating or cooling the kiln too quickly, which also stresses the
