The production capacity of ordinary heavy calcium in the domestic market has become saturated, and the product price is low, and the technological content and added value are not high. For ultra-fine and active heavy calcium, domestic production capacity cannot meet the demand and still has great market potential. Overall, the main development trends of heavy calcium carbonate industry technology are large-scale, functional and intelligent. This is an inevitable requirement for the intensification, stabilization, structural optimization or specialization of heavy calcium carbonate production, as well as improving production efficiency, reducing energy consumption, wear and tear and reducing production costs. It is also an inevitable requirement for the development of production technology due to the significant increase in market demand and saving the amount of resin in polymer-based composite materials.It is necessary for domestic heavy calcium carbonate companies to learn from the successful experiences of world-famous calcium carbonate companies such as Omya and Imerys, and adopt high-efficiency, energy-saving large-scale equipment and advanced production technology to promote the in-depth development of my country’s heavy calcium carbonate industry in terms of scale and product refinement.As an equipment supplier recognized by Omya, HCM has provided calcium powder processing machinery and equipment to many Omya factories around the world, which are highly praised and favored by customers. If you have purchasing needs for calcium powder processing machinery and equipment, please contact us for details of the equipment. Email:hcmkt@hcmilling.com
