Our company is a top notch Manufacturer, Supplier and Exporter of Mica Flakes from Jharkhand, India. We package the Mica Flakes in high-grade materials so there is no loss in the quality or properties during storage or transportation. We are proficient in handling bulk orders of Mica Flakes and ensuring their timely delivery.

Highlights : Mica Natural Flakes are made out of selected Mica Scrap, Dried, and 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 be 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.

• In 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 meshes. These flakes and powder are classified into various mesh sizes with the help of sieve classifiers.
  • Coarse Mica Flakes: Plus 6 mesh, having a bulk density of 0.17kg/ltr. Have high percentage of relatively large flakes for sealing large openings.
  • Medium coarse mica flakes: Plus 10 meshes having a bulk density of 0.18kg/ltr. Area generally used to combat mild circulation losses in porous information
  • Fine Mica flakes: Plus 20 mesh having a bulk density of 0.20 kg/ltr is particularly used when a sealing agent is needed small enough to allow the mud to pass through a shaker screen without interfering with the operation.

Specifications :

• Uses : Natural muscovite mica flakes are used as raw mica material for regrinding, micronizing, sheet and pulp manufacturing for mica paper. Small sized of mica flakes are required for roofing felt industries, decorative purpose & mica board manufacturing to insulate the wall of houses for preventing noise, heat & ultra violet rays.
• Packing : It depends up to the customer. Generally it's packed in HDP, jute or paper bag of 10, 25, 50kgs.
• Delivery : Minimum one 20' T.E.U. (full container load of 20 ton)
• Inspection : Can be carried out by the buyer or the buyer nominated independent inspection agency before shipment at our works
• Capacity : In our machine we can produce 10 tons per duly screened.

• 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 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.
• Mica powder in various forms is obtained by grinding/breaking mica scrap, which is a slow costly & extremely complicated process, because of the scrap being tough and having plate like structure. Meticulous care & precaution has to be taken so that is no deterioration of its natural brilliance, color and properties
• Our factories are fully equipped with latest grinding media, pulverizers and classifiers. Powder testing equipments are present there to control quality, mesh size etc.
• Personals always supervise the production, packing, transportation of raw material to end product for the satisfaction of the customers.

General Characteristic of Dry Ground Mica Powder :

• It is highly responsive to the action of light, heat electricity, water and other chemicals.
• It transmits and reflects light to produce decorative effects and also prevents penetration of "SUN" rays, moisture, heat, gases etc. on the surface on which it's coated.
• It produces stiffening effect of calendered sheets.

• It has very high lubrication value and can be used as :
  • High temperature grease, mould release etc. in rubber & plastics
  • Dusting surface.
  • Anti Friction powder of compounds.

• It produce lifting effects in liquid products due to low specific gravity and as such, remain uniformly dispersed over the surface of liquid vehicles.
• It has excellent di-electric & thermal insulation properties.
• It has very little abrasive effect and can easily get wetted by resin and dyes.
• It has an excellent anti-sticking property and as such, during vulcanization, it prevents sticking and movement of sulphur, at the same time, it permits the air bubbles to escape.
