Medium-speed micro-grinding enables kaolin widely used in the paper industry

Kaolin is a common mineral, soft white color, has a good plasticity, adhesion, fire resistance and excellent electrical insulating properties, it is also these advantages can make obtaining in the ceramic, rubber, chemicals, paints, pharmaceuticals, especiallyis widely used in the paper industry.

Application of kaolin in the paper and other industrial sectors, need for technical processing become a powder mill equipment processing, integration with other industrial materials, and then can be used in the manufacture of industrial products. Kaolin grinding into a powder fineness of its plasticity, the slurry viscosity, ion-exchange capacity, molding performance, drying performance, firing properties have a significant impact on the mill whether kaolin processing to the required fineness of industrial production, will directly affect the effect of kaolin application.

Although the various industrial sectors on the different uses of kaolin has a specific particle size and fineness requirements, but high in some industrial sectors such as paper, paint kaolin into a powder fineness, such as the United States as a paper filler kaolinrequirements of less than 2μm (microns) accounted for 78-80%, as a coating to less than 2μm content accounted for 90-95%. However, the difficulty of processing such ultra-fine powder, fine powder mill equipment demanding, therefore, we must choose the high-performance micro-grinding equipment.

The HGM ring medium speed micro powder mill, Henan Liming Heavy Industry Science & Technology Co., Ltd. introduced advanced milling technology in Sweden, for the domestic milling industry trends and market demand, developed to produce a fine powder and ultrafine powderThe new grinding and processing equipment. The device uses the extension of continuous polishing, grinding recycled many times, and finished a finer granularity (the smallest up to 3250 mesh), milling efficiency, kaolin, bentonite, limestone, calcium carbonate material at the same time, have exceptional performance in the processing of talc, mica, illite, pyrophyllite, vermiculite, barite, gypsum, alunite, graphite, fluorite and other material for high fine powder.

The liming Heavy Industry (shanghai) HGM ring medium speed micro powder mill has been widely used in the processing of the major kaolin mine, by the kaolin superfine powder grinding process has been successfully applied to the coated paper, coated paperindustrial production, gives the paper good coverage performance and coating luster performance, increase the whiteness of the paper, opacity, smoothness and printability, which greatly improves the quality of the paper by the paper industry's consistentrecognition.
