How James Hardie Went From Asbestos To Cement King

James Hardie's first breakthrough came in 1923 when the company introduced the "Sutton Process." Named after the employee who had developed it, the process used flat sheets of asbestos cement wrapped around a mandrel and cured underwater to form pipes. This pipe-making process was particularly beneficial due to the low capital cost it ...

The Cement Manufacturing Process - Advancing Mining

Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are ...
