Chenxing Mica Your Economic Choice for Industrial Applications A group of minerals having perfect basal cleavage and capable of splitting into thin laminae is called mica. Chemically they contain complex silicate of aluminium and alkalies with hydroxyl.Taking the advantage of large reserve and mining capacity of muscovite mica mine, Chenxing company has been producing mica products since early 1960, our products have been sold to USA, South Korea, Japan, Europe and are widely applied in the fields:l Automotivel Paints and coatingl Plastics l Plasterboard and joint compoundsl Pearlescent pigmentl Rubberl Drillingl Brake pad & clutches Dry Ground Muscovite Mica Quick ViewMuscovite Mica Specific Gravity 2.6 Refractive Index 1.58 MOH hardness 2.5 pH value 6.5-7.5 CommodityDefinition Size Raw materialsMica scrap8-20meshDryMicaPowderSeriesBuildingmaterials20mesh40mesh60mesh80mesh100mesh16-30 mesh40-100meshPlasticGrade60mesh100mesh200mesh325mesh400mesh600mesh Wet Ground Muscovite Mica Scrap mica is ground by three processes, namely dry grinding, wet grinding and micronising. The marketed product is classified according to the grinding process which indicates quality and properties like colour, mesh size and bulk density. Dry mica powder is prepared by grinding in high speed hammer mills. The edges of the flakes get crushed and powdered mica is produced which gives the appearance of flour. Wet-ground mica is produced by grinding in water involving preferential delamination of flakes. Churn mills, with large wheels or rollers rotating on horizontal shafts are used for this purpose.
