Cement and Lime | Tunstead

The Tunstead site is home to one of the largest limestone quarries in Europe, producing over six million tonnes of stone a year. The process is highly efficient as the extraction of limestone, production of lime and cement are all intrinsically linked and over 99% of quarried material is converted into saleable products and the remainder is used on site for restoration purposes.

Stage 1: Quarry Process | Cement Production

Limestone Quarries. Limestone is the chief ingredient in powdered cement. Limestone in most all regions is quarried rock. In brief, Limestone is drilled, blasted and loaded into Haul trucks. From there it travels to a Crushing Unit. Sometimes there is a combination of Primary and Secondary Crushers used to reduce the limestone to a usable size.

Manufacturing Process of Portland Cement

The manufacture of Portland Cement takes place in a number of steps: At TCL''s Mayo Quarry, limestone, one of the main ingredients in cement manufacture, is excavated. The limestone raw material then goes through several categories of ''crushing'', until it is fine enough for water, sand and iron oxide to be added to produce a mixture known as Slurry.
