Calcium carbonate crushing processing

Calcium carbonates are composed of the crystalline mineral, calcite, which occurs naturally in the form of chalk, marble or limestone. Chalk is usually finely textured and is relatively impure. Marble deposits are limestones changed by recrystallisation under conditions of extreme heat and pressure. In some cases, this natural process yields pure marble of exceptional whiteness, such as the famous deposits of Carrara in Northern Italy. Calcium carbonates are widely used as extenders in a variety of coatings.


The Moh’s hardness of calcium carbonate is 3,which means calcium carbonate is easy to crushing, in a whole calcium carbonate crushing process line, we provide jaw crusher for primary crushing, and impact crusher or cone crusher for fine crushing.we provide two types of jaw crusher, PE Jaw crusher and PEW jaw crusher which is an advanced jaw crusher, we provide two types of impact crushers,and four types of cone crusher. besides ,we also provide mobile crushing plant for calcium carbonate crushing processing.
