Feb 10, 2016· The production process for portland cement first involves grinding limestone or chalk and alumina and silica from shale or clay. The raw materials are proportioned, mixed, and then burned in large rotary kilns at approximately 2500°F until partially fused into marble-sized masses known as clinker. After the clinker cools, gypsum is added, and both materials are ground into a fine powder which is portland …
