A. A Boateng, in Rotary Kilns (Second Edition), 2016. 10.4 The Cement-Making Process. Rotary kilns are synonymous with cement making, being the workhorses of this industry. There are many types of rotary kiln arrangements for producing cement clinker with each incremental design goal aimed at improving energy efficiency, ease of operation, and product quality and minimizing environmental ...

Rotary Kiln - an overview | ScienceDirect Topics

Whenever the operator increases kiln speed, kiln inlet temperature will decreases, requiring increasing fuel rate to the kiln. Any increase in the fuel rate will require an adjustment in kiln fuel rate and an increase I.D. fan speed. Both should be increase in a manner equal to that practiced in increasing kiln speed. 5.Clinker cooler control

Within the British context, the simple "long" kiln with a rotary or planetary cooler was the norm in the first half of the twentieth century, and in this simple system the ground rules of kiln control were developed. The operator has four basic controls: kiln rotational speed – which controls the rate at which the feed advances down the kiln

VFD in Cement Industry - Variable Speed Drives

Therefore, in the operation of rotary kiln, we need to judge the calcination temperature through the parameters of current, NO x and flame temperature at the kiln head, and adjust the coal feeding rate, raw material feeding rate, air flow rate, secondary and tertiary air temperature and kiln speed to control the calcination temperature in an appropriate range.

Cement Kilns: Kiln Control

In cement plants, VFDs provide controlled torque and speed to the kiln, which increases the life of the mechanical system, and reduces maintenance and operating costs. The VFDs also provide feedback signals, which improve cement kiln process control. Gozuk provides both ac and dc drive technology suitable for cement kiln applications.
