Mill Machine for Calcium Carbonate
In the past ten years, the rapid increase of China's heavy calcium carbonate production, nearly 15 times in 5.2 million tons. Coarse whiting industry in China is developing so quickly, because which are benefit for the mill industry development, especially in Shanghai Clirik HGM series ultrafine
mill machine.
Ultrafine mill machine is used for the ultimate equipment, powder grinding calcium carbonate can be processed up to 3000 mesh. Coarse whiting powder is widely used in rubber, plastic, papermaking, coating, paint, toothpaste, sticky thorns, and other fields. Can say milling machinery in our country is every innovation in different degree to promote the development of coarse whiting powder industry.
At first, the slow development of industry of our country coarse whiting and a large gap compared with developed countries, such as basic research is weak, backward technology and equipment, research depth and breadth in the field of application is not enough, and so on. China's heavy calcium carbonate scale production began in the early 1980 s, calcium carbonate products in domestic market, each enterprise on the initial carbonate is mainly produced 100, 200, the purpose of coarse powder.
Later, with the popularity of Raymond mill, to start producing purpose products, 325 ~ 600 in the 90 s, with the widely application of the classifier, 800 ~ 1250 purpose products appeared on the market; In the mid - 90 - s, began to spread, wet process can produce superfine heavy calcium carbonate, 2500 ~ 12500 from the superfine heavy calcium carbonate into a fast developing period. According to China's non-metallic mineral industry association of professional committee of the calcium carbonate, calcium carbonate processing enterprises nearly thousand at present in China, which has a certain scale of more than 400 heavy calcium carbonate, the annual output 4 million tons, the product structure, accounted for 50% of 200 ~ 325 mesh, 325 ~ 35% 1250 mesh, 1250 mesh for more than 15%, after surface treatment (12%)
Ultrafine mill machine is processed into coarse whiting will heavy calcium carbonate powder and use, coarse whiting powder production methods are divided into two kinds of dry method and wet method. Below 2500 mesh products, is dry process production; 2500-6500 products, usually with wet production advisable. At present, the world's large-scale enterprises dry processing in processing equipment and technology such as vertical mill. Dry process equipment mainly include Raymond mill, three-ring medium superfine mill and vertical mill, the equipment between the product market demand for further improvement.
