The increasing domestic market demand for heavy calcium powder leads to the prosperity of the domestic heavy calcium powder mill industry. The main component of marble is calcium carbonate, , accounting for more than 50% of it, so calcium is the main raw material for the production of heavy calcium. Marble contains of calcium carbonate, iron, magnesium, manganese oxide, and its powder material can be used as a pure chemical product, but also can be used as industrial processing raw materials and ecological repair feedstock.

We know that the mineral resource experiences its deep processing through breaker machine and grinding plant, which can significantly improve the utilization of the ore, so this is undoubtedly the opportunities to reverse the passive situation for domestic mineral enterprises. Deep processing of ore needs basic equipment including: crushing plant, and all types of mill equipment. In order to meet the development needs of the trend of large quantities of mineral processing, the production and processing efforts of crushing equipment and grinding mills products will inevitably need to have a greater degree of improvement, which promotes the crusher and mill production enterprises to accelerate technology research and development and introduces more efficient milling equipments.
