the high-pressure micropowder grinder is a new type of high-efficiency, which is developed by the engineers through several years' hard work depending on the production experiences.it adopts the fineness grading technology from germany and japan and tackles the difficulty in classifying super-powders. it is mainly used in super-powder processing with more than 500 kinds of materials, such as feldspar, talcum, barite,marble, limestone, charcoal blacks, and china clay, with a fineness of 500 meshes (25um) to 2500 meshes (5um) and the minimal fineness of 3500 meshes (3.55um).
