Mineral powder is widely used in the fields of building materials, chemical industry, metallurgy, etc. Mineral powder can be used as a raw material for various fillers, such as rubber products, plastic products, paints, coatings, etc., which can increase the strength, hardness and wear resistance of materials. Adding mineral powder to building materials such as cement and concrete can improve their compressive strength and adjust the various properties of materials.
