In the calcium carbonate industry, especially heavy calcium carbonate, there are problems such as power consumption, ore loss, dust and noise pollution in the production process. Heavy calcium enterprises must fully realize green and sustainable development from the aspects of product transformation, process control and waste reduction treatment.

1. Product - Refinement and functionalization

my country's heavy calcium has higher value is its deep processing products - fine, high-purity, surface modification products. At present, the downstream market has put forward higher and higher requirements for heavy calcium products. The refinement of heavy calcium products is a direction of future development. To achieve product refinement, large-scale wet/dry equipment technology, modified equipment and ultra-fine A complete set of technology for graders. The functionalization of calcium carbonate products is more reflected in appropriate surface treatment, such as providing compound active agents in a targeted manner, surface treatment with stearic acid and coconut oil, and silane coupling active agents to enhance active heavy carbonic acid. calcium quality level, expand service areas, and improve application value.

2. Production - large scale

my country's heavy calcium production enterprises have a large production capacity, with an annual production capacity ranging from 100,000 tons to hundreds of thousands of tons or even millions of tons. However, there are only a handful of heavy calcium production equipment with a unit output of 50,000 tons. Large-scale high-efficiency energy-saving production equipment and advanced production technology can be used to achieve the purpose of reducing energy consumption. It can learn from the successful production and management concepts of world-renowned calcium carbonate companies, such as vertical mill/ball mill and other large-scale dry grinding equipment and ultra-fine classifier combination technology.

3. Waste - Recycling and Reduction

Enterprises should establish a waste water recycling center, and concentrate all the domestic and industrial water waste water pipes in the factory to the waste water treatment center, and adopt the methods of flocculation, sedimentation, recovery and recycling to save water and reduce waste discharge. For coal combustion, high-heat and low-sulfur coal should be selected. At the same time, the waste gas generated by coal combustion should be dedusted by water film, and then discharged after purification.
