cement and limestone mining
Cement Production
The cement production process, for example, starts with mining of limestone, which is then crushed and ground to powder. It is then preheated to save energy before being transferred to the kiln, the heart of the process. The kiln is then heated to a high temperature of up to 1480 degrees to convert the material to a molten form called clinker.

Electrification is driving sustainability in cement and mining
It captures excess power and converts limestone into hydrated lime through electrolysis. This is a process demonstrated at laboratory scale, which we are conducting with our academic partnerships. Such a cement plant could be small scale, decentralised, automated, easy to deploy, easy to start-up and shut down. It is a very different approach

03.05.2022By replacing some of the clinker in the cement, which is the main energy-intensive ingredient, with limestone, you are reducing the level of carbon emissions from the cement's production. As limestone grinds finer than clinker, the result is a far denser particle packing with increased particle distribution.

Cement manufacturing begins with quarrying operations in which limestone in mines is quarried and brought to crusher for crushing. Limestone quarries are opencast mines. Often limestone appears as an outcrop right on the surface. At other times it is under an overburden that can vary in depth but is generally less than 3 metres thick.
