·HOW GREEN ISLAND CEMENT IS MADE
4༔
Green Island Cement is manufactured from hard limestone and, clay. It is necessary that these materials should be finely ground in order that they may come into intimate contact with one another in the burning process.
The finely pulverised materials are mixed in a certain definite proportion, "roughly one. part of clay to three of limestone, and are fed to the Rotary Kilns.
In these kilns they meet the hot gases and flames generated by pulverised coal blown in at the other end of the kilns, and after various chemical actions have taken place, they combine to form Portland Cement Clinker..
The Clinker is ground down with a small percentage of gypsum, to regulate the setting time, and Green Island Portland Cement is thus produced.
Although sounding so simple, in reality the process is an intricate combination of mechanical, physical and chemical operations, needing great akill and care. Nothing but constant and accurate supervision will yield the results so well-known with Green Island Cement, namely, strength, uniformity and reliability.
