Annual output of 200,000 tons of heavy calcium carbonate grinding plant

Posted: May 17, 2018 Source: Kefid Shanghai Machinery Views:

Heavy calcium carbonate is ground by natural carbonate minerals such as calcite, marble, and limestone. Heavy calcium powder is a commonly used powdery inorganic filler, widely used in rubber, plastics, paints, coatings, papermaking and other industries.
 
Heavy calcium powder processing is divided into general fineness processing (80-400 mesh) and ultrafine powder processing (400-3000 mesh).
 
80-400 mesh (200 micron-33 micron) heavy calcium powder production technology and process:
 
For this fineness range calcium powder processing,we can select Kefid's European type grinding mill or vertical mill. It is all dry-processed. Through high-efficiency separators, the mill can make preparation of heavy calcium powder without external screening or sorting. Due to use of internal circulating air, the heavy calcium powder that meets the finished product can be quickly blown out, completely avoiding the phenomenon of excessive grinding, which greatly increases the capacity and production efficiency. At the same time, due to the use of advanced dust collectors, the system meets the national environmental protection requirements.
 
Among them, the European type grinding mill's capacity is 3-50t/h, vertical mill's capacity is 6-80t/h.They can meet the needs of an annual output of 200,000 tons of heavy calcium carbonate production.
 
425-3000 mesh (3 micron-33 micron) heavy calcium powder production technology:
 
For this range of heavy calcium powder processing,we can choose LUM ultra-fine vertical mill and ultra-fine powder mill. They are mainly used for the grinding of ultra-fine calcium carbonate. The fineness of the finished product is D97 = 3-33μm.
 
Because the fineness of the finished product is improved, the capacity of the machine is naturally reduced, we will choose the right equipment according to the actual production demand.
