Ground calcium carbonate manufacturing process

Production process of ground calcium carbonate 1. Dry production process First, manually select calcite, limestone, chalk, shells, etc. from the quarry to remove the gangue; then use a crusher to coarsely crush the limestone, and then use a Raymond mill (pendulum) to grind to obtain fine limestone powder. Finally, the classifier is used to classify the milling powder, and the powder that meets ...

Manufacturing Process - Tums

Manufacturing Process Calcium carbonate is often made into chalk or limestone, but is also the main ingredient in Tums. This compound is a raw material, and is also the most commonly found organic compound. It can be found in many places, for example: rocks, caves, and even sea shells! Although calcium carbonate can be used as chalk, it can also be used in edible items.
