Daruka Isolants - Manufacturer and exporter of mica powder. India is the biggest producer of muscovite sheet mica in the world. This type of mica is also called Potassium Mica and is the best variety available in the global world. It is tough, chemically inert, immune to climatic variations, non toxic, transparent and water proof. By virtue of these unique qualities, it can be reduced to very small thin particle having diameter to thickness ratio as high as 25 to 1. It can therefore, be transformed into coarse, medium & fine varieties of flakes and powder by dry process of pulverization and there by it renders itself to wide commercial application in these forms.

Specification Muscovite Ruby Natural Processed Mica Flakes Daruka Mica Natural Flakes are made out of selected Mica Scrap, Dried, Screened & Sheared. Process: First the selected mica scrap is dried to avoid any humidity. Secondly mica scrap is screened to avoid dust. Thirdly all the foreign particles like biotite (black Mica), quartz, straw, bamboo (organic & inorganic materials) are removed by hand picking. Here we again screen the material. Now the material is ready to sheared (in grinding machine). Grinded material is then directly through blower sucked & blown in a round screen which is having blower to separate dust from the grinded material & the 8 mesh screen size to bring down the 2-8mesh NATURAL MUSCOVITE RUBY MICA FLAKES.Mica FlakesIn this case, mica scrap & waste are pulverized by mechanical grinders such as high speed hammer, rod, attrition, mills or cage distintefrators which reduce them to flakes and powder of different mesh sized ranging from 2 to 300 mesh. These flakes and powder are classified into various mesh sizes with the help of sieve classifiers.
