Portland Cement Clinker - an overview | ScienceDirect Topics
Portland cement clinker is nodules (diameters, 5–25 mm) of sintered material produced by heating a homogeneous mixture of raw materials in a kiln to a sintering temperature of approximately 1450 °C for modern cements.The resulting clinker consists of four main minerals: 11 1. Alite or tricalcium silicate, Ca 3 SiO 5 (in oxide terms 3CaO.SiO 2), abbreviated to C 3 S;

The essentials of electrical systems in cement plants | EEP
All machines are driven by electric motors. Majority of the motors are 400- 440 volts. A selected few motors of higher ratings are MV motors with 3300, or 6600 or 11000 volts. Most motors are fixed speed and unidirectional motors. Motors for kilns and coolers, feeders, and some fans are variable speed motors.
What Is Exhaust Gas Recirculation (EGR) & How It Works?
The term EGR stands for Exhaust Gas Recirculation. It is a part of modern-day diesel engine vehicles which helps to decrease the Nitrogen Oxide (NOx) emissions. Exhaust Gas Recirculation is the technique used for reducing the nitrogen oxide in both the internal combustion diesel engines as well as petrol engines.

Milling Machine: Parts, Types, Operations, Milling Cutter ...
Milling is the machining process in which the removal of metal takes place due to the cutting action of a rotating milling cutter.In a milling machine, the cutter is rotating due to workpiece is fed against it.This machine can hold more than one tool at a time. The cutter rotates at high speed, and because of the many cutting edges, it removes metal at a very fast rate.

History of Portland Cement in the United States
On the other hand, portland cement is an artificial mixture of raw materials, has a calcination at a temperature above 2,000 degrees Fahrenheit, and purer raw materials were used than necessary for natural cements. The raw materials used in the manufacturing of portland cement at this time were cement rock, limestone, shale, and coal.

Rawmill - Wikipedia
A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect …
