Superfine Pendulum Grinding Mill Protects Talc Powder Industrial Coatings

Experts of Guilin Mining Machinery Co., Ltd. absorbed advanced fine classification technology from Germany and Japan on the basis of many years'research on industrial grinders. According to the principle of fluid mechanics, they devoted themselves to developing Pendulum Grinding Mill, which is comparable to air grinding, thus solving the problem of the high cost of air grinding in China and the difficulty of classification of ultra-fine powder. The output and energy consumption of Pendulum Grinding Mill has reached the national standard, ranking in the advanced level at home and abroad, and are highly praised by users in various industries. The machine is mainly suitable for grinding and grinding of various materials, mainly used for ultra-fine powder processing of more than 500 kinds of materials, such as kaolin, limestone, calcite, marble, barite, gypsum, iron oxide, iron green, aluminium hydroxide, pigments, clay, coal, activated carbon, feldspar, calcite, talc, barite, marble, limestone, carbon black and clay, with fineness of 500 meshes (25 meshes). The finest powder is 3500 meshes (3.55 microns).

Magnesium silicate is the chemical name of talc powder. Talc ore is abundant in reserves all over the world, usually a mixture of various crystal forms. Generally, the deep processing of talc must be ground into a fine powder of various sizes through a grinder, and then applied to various fields. The influence of industrial talc powder on the performance of coatings is controlled by its structure type, powder fineness, and particle size distribution. Therefore, we classify the products of talc powder: fibrous talc powder, flake talc powder, and granular talc powder. It can be seen from the application of talc powder that both coarse and fine powders are widely used.

Talc powder is easily wetted and dispersed in all liquid coatings, such as organic solvents, varnishes, alkyd and water systems. Talc powder has excellent suspension property in coatings and can also help other pigments in the system to keep suspension state. Coarser talc powder is suitable for coatings requiring rough or "dentate" coatings, such as interior wall paints, primers, and crepe paints. Medium-sized varieties are suitable for house paints and general fillers. Ultrafine talc powder is suitable for controlling the gloss, consistency and hanging property of semi-gloss coatings. Talc powder is widely used in cement, Crack Filler and putty. According to different requirements, talc powder with coarse or fine particle size is selected for special products.
