How A Quarry Works
The process starts by breaking off large chunks of rock from the quarry walls, usually through controlled blasting. This rock is then moved using loaders and trucks to a primary crusher. THE PRIMARY CRUSHER. The crusher reduces the overall size of the material to make it easier to process.

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.
