Zhejiang Fengli ultra-fine roller grinding into the first choice for non-ore deep processing equipment

Ultrafine grinding technology plays an increasingly important role in all areas of the national economy. In particular, the use of non-metallic minerals depends on the degree of deep processing. The effective ultra-fine grinding is the prerequisite and guarantee for various deep processing. Ultra-fine roller pressure grinding is one of the most important deep processing technologies. Because most non-metallic materials are crushed under the action of ordinary mechanical impact force is difficult to reach 1000 mesh (13 microns) or more. For the non-metallic materials that need to reach 1000 mesh (13 microns) or more, the best way to crush is to use a roller mill. For this reason, scientists and technicians from various countries have conducted a lot of research in this area, hoping to find an ideal method that can superfine such materials at room temperature. Research in this area has been fruitful for the former Soviet Union, the United States, Britain and Japan. Germany's research in this area is also very systematic and comprehensive. There is a rotatory method of rotation and revolution that can crush non-metallic minerals above 1000 mesh (13 microns) at room temperature, and the yield is high.
China's non-metallic mineral processing equipment - ultra-fine roller mill production is still in its infancy, so far, the country has not yet established a good model, generally still use the ordinary crusher to crush, it is difficult to achieve the ideal Requirements; the use of jet crushing costs too high, it is difficult to be accepted by the industry.
The national high-tech enterprise Zhejiang Fengli Crushing Equipment Co., Ltd., which enjoys the reputation of “China Crusher Expert”, aims to improve the status quo of non-metallic mineral powder processing equipment in China and improve the level of non-metallic mineral powder deep processing technology, introducing advanced powder technology from Germany. Combining years of experience in producing various types of smashing equipment, we have independently innovated and successfully developed a super-compact, high-efficiency, small-footprint, easy-to-install, uniform-grained product that can match the level of similar foreign products. Grinding equipment - CGM ultra-fine roller mill, suitable for ultra-fine grinding of kaolin, limestone, calcite, talc, graphite, carbon black and other non-inflammable and explosive materials with moisture of less than 8% and Mohs hardness of 6 or less. It is an ideal deep processing equipment for non-metallic mineral powder materials. Satisfy the demand for such equipment in the non-metallic mineral industry, and break the situation that has long relied on imports. Not long ago, this equipment has been appraised as a new product in Zhejiang Province in 2014.
The new product is an internal classification high-pressure ultra-fine roller grinding, which can complete the two processes of fine powder grinding and fine powder separation at the same time.
Its superior performance is: First, compared with Raymond Mill, jet mill, the production efficiency is more than doubled under the same power conditions, the rolling force of the grinding wheel on the material is increased by 30% to 40% under the action of high-pressure centrifugal force. The second is that the output is large. When the calcium carbonate is crushed, when the fineness is 10 microns, the output per hour can reach more than 1 ton. Third, the product fineness index is good, d97 = 35 ~ 3 microns, to achieve the fluid bed type jet mill fineness index. Fourth, stepless speed governor equipped with stepless impeller can adjust the granularity of the product without shutting down the machine, and the fine powder can be completely recovered without polluting the environment. Fifth, the complete set of equipment is easy to install and no large-scale civil engineering is required. Equipment can be put into production after installation. Sixth, the dust removal effect fully meets the national dust emission standards.
