Technical advantages

①       This technology not only utilize the waste but also promote the energy conservation of the traditional light calcium carbonate industry and reduce the consumption of limestone resources.

②       The production process maintains a closed-loop material recycling, which greatly reduce the material consumption and achieve an environmentally friendly production.

③       Compared with the traditional light calcium carbonate production enterprises, the unit output investment with the production and operation costs are substantially reduced, which makes the enterprise more competitive.

④       The performance indicators of light calcium carbonate products meet and exceed the standard of HG / T21776-1996.
