Despite these difficulties, existing literature has focussed on creating one-dimensional models which can capture quantitatively the kiln operation while.

Top Applications for Rotary Kilns - FEECO International, Inc.

A cement plant uses a rotary kiln, also referred to as a cement kiln or rotary cement kiln, to heat raw material into a product commonly referred to as 'clinker.' While the types of cement kilns have changed and evolved over the years, modern cement processing typically uses a continuous direct fired kiln to thermally process.
