A few years later, in 1845, Isaac Johnson made the first modern Portland Cement by firing a mixture of chalk and clay at much higher temperatures, similar to those used today. At these temperatures (1400C-1500C), clinkering occurs and minerals form which are very reactive and more strongly cementitious.

Nowadays many cement factories used modern production technology to increase capacity and quality of cement. In modern technology, they use the equipment, such as a cross belt analyzer manufactured by Gamma-Metrics of USA to find the composition of limestone at the conveyor belts, high-pressure twin roller press, six-stage preheater, and vertical roller mill.

When envisioning the cement plant of the future, it is important to understand the reference for a typical plant today. Our reference plant is a five-stage preheater-calciner kiln with a vertical raw mill and two cement ball mills. It has an annual production capacity of one million metric tons of cement and produces several types of cement.
