Calcium carbonate powder that is supplied without any additional coating or treatment to its surface is called an uncoated calcium carbonate powder. It is produced in our factory where we use heavy-duty machines to crush and grind the calcium carbonate lumps into fine powder. Paint, paper, and other industries demand this fine powder to use in their production processes as a filler that also improves the consistency of products and enhances their properties. It is also added to building materials as a filler. The other uses of uncoated calcium carbonate powder are agriculture and gardening
