[0002] The main component of limestone is calcium carbonate, an inorganic compound that is commonly used in the construction industry, papermaking industry and rubber products. With the continuous advancement of science and technology and the development of nanotechnology, the application field of calcium carbonate will be further broadened. In the production process of calcium carbonate, the limestone raw materials need to be crushed first, so a crushing device is needed to perform the crushing work.
