Ground Calcium Carbonate (GCC), also known as ground limestone powder, is an inorganic powder material produced by mechanical crushing and classification of natural carbonate minerals such as calcite, marble, limestone and chalk. Unlike precipitated calcium carbonate (PCC) made by chemical precipitation, GCC retains the crystal structure of raw ores. It features high chemical purity, high whiteness, low oil absorption, good dispersibility and competitive price. As an important industrial filler, GCC is widely used in papermaking, plastics, rubber, coatings, building materials, feed and other industries. It effectively increases product volume, reduces costs and improves the physical and mechanical properties of finished products.
Compared with PCC, GCC has higher production capacity, lower manufacturing cost and strong market demand. Equipped with LM Vertical Roller Mill, LUM Ultrafine Vertical Mill, MTW European Trapezium Mill and other equipment, large-scale GCC grinding production lines can be built to stably supply mineral powder of various specifications for different industries.
