Optimization of the geometry of cyclone separators used

This study presents the possibilities for improving the process of clinker burning by optimizing the geometry of first-stage cyclones that form a part of a cyclone suspension preheater. Due to the high energy consumption and scale of the process involved in cement production, the aim is to improve the efficiency of the system.

Cyclone (cement) – buildup measurement VEGA

In clinker production, cyclones are used to preheat the raw meal. Before the raw meal enters the rotary kiln it is preheated to +900 °C in the cyclone. Constant monitoring of the buildup thickness on the walls ensures a continuous process.

Parametric Studies of Cement Production Processes

The cement industry is one of the most intensive energy consumers in the industrial sectors. The energy consumption represents 40% to 60% of production cost. Additionally, the cement industry contributes around 5% to 8% of all man-made CO 2 emissions. Physiochemical and thermochemical reactions involved in cement kilns are still not well understood because of their complexity.
