Mica Dealers in Bow Bazar, Kolkata

We offer mica is a complex hydrous potassium-aluminum silicate mineral, common in igneous and metamorphic rocks, characteristically splitting into flexible sheets used in insulation and electrical equipment. Mica is invaluable in the electrical industry because of its unique combination of physical, chemical and thermal properties, low power loss factor, dielectric constant and dielectric strength. Dieletric strength is the ability to withstand high voltage without puncturing. mica flakes is mica scrap ground into sizes ranging from 2 mesh to 30 mesh. This material is prepared mainly by the means of rotary hammer crushing machine in which the mica is literally beaten till such time that the required size is not achieved and the material passes out from graded sieves attached therein. mica scrap is obtained from mica mines, it is screened over ½" sq. Inches openings and have an average size between 12 mm – 50 mm with thickness between 0.15 mm – 5 mm. Mica scrap should be cleaned, dried, hard, free from mineral and non-mineral impurities, such as: quartz, felspar, garnet, tourmaline, stones, mud-stained or biotite mica, clay, send as well as other inclusions such as paper, wood-leaves, straw, iron contents etc. mica powder in various forms is obtained by grinding/breaking mica scrap. Meticulous care and precaution has to be taken so that there is no deterioration of its natural brilliance, colour and properties
