A calcite crushing and screening machine is used to process calcite ore into various sizes for different industrial applications. Calcite is a mineral composed of calcium carbonate (CaCO₃) and is widely used in industries such as construction, agriculture, pharmaceuticals, and manufacturing. The crushing process reduces large calcite rocks into smaller particles, while the screening process separates these particles into specific sizes. This ensures that the final product meets the required specifications for its intended use, such as in the production of cement, lime, or as a filler in plastics and paints.
