HOW GREEN ISLAND CEMENT IS MADE
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,
gases
In these kilns they meet the hot and flames generated by. pulverised coal blown in at the other end of the kilne, 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 operatione, needing great skill and care. Nothing but. constant and. accurate supervision will yield the results s0 well-known with Green Island Cement, namely, strength, uniformity and reliability.
