When the coal burns inside the boiler completely, some of the fine particles such as talcum powder is carried out of it. Those fine particles are called Fly Ash. We make use of advanced devices such as Bag Houses, FGD Systems, Electrostatic Precipitators, etc., we remove the Fly Ash particles from the stacked gases, which are further collected for recycling purposes. We offer the Fly Ash that are heterogeneous glassy substance consisting of silicon, iron, magnesium, silica, calcium and alumina, which in presence of water will combine chemically with the aid of traces of lime that is present in fly ash, to obtain cementitious properties (pozzolan). Our Fly Ash is also high in calcium compounds, which give them a self-hardening property, whenever mixed with water. Some chemical analysis will also depict the Fly Ash compounds to be present as oxides of the chemicals, of which it is made of. However, these compounds occur as aluminosilicate glass interspersed with a small fraction of crystalline compounds, like magnetite, quartz, hematite, mullite, and elemental siliceous or aluminosilicate glass. We offer

• Class F Fly Ash
  • It is produced from the burning of anthracite or bituminous coal
  • It contains silica, aluminum and iron in combinations of greater than 70%
• Class C Fly Ash
  • It is produced from the burning of lignite or subbituminous coal
  • It generally contains more calcium and less iron with its lime (CaO) content in the range of 15% to 30%.
  • It is cementious in addition to pozzolanic.

We are a credible Supplier of Cenosphere. The Cenosphere are hollow glass particles and are also known by the name hollow ceramic spheres, microspheres and glass beads. Known for their unique combination of controlled sizing (prior to processing), spherical shape, exceptional strength in uniform compression, high acoustical and thermal insulating and dielectric properties. These properties of the Cenosphere make them most suited raw materials for preparing high value applications. In addition, we offer reliable marketing and development Services of diverse Cenosphere Applications. The small amount of Cenosphere material may have high market value if its production remains constant over a long period of time. General Physical Features

• 20m-200m in diameter and are spherical, coherent, non-porous shells of silicate glass
• The thickness of the shell is about 10% of the radius
• The floating spheres are usually collected from lagoons
• True particle densities of the individual sphere range from 0.40-0.60 gm/cc, and their bulk densities are 0.25-0.40 gm/cc
• The Cenospheres break down on heating to 300^oC, which indicates release of water dissolved inside the glassy material. The hollow spheres start to sinter at 1200^oC and usually collapse above 1300^oC.
• The cenospheres are formed at an estimated temperature of 1400^oC and the formation and size are governed by the viscosity and surface tension of the fused silicate glass, by the rate of change in particle temperature and by the rate of diffusion of gases in the silicate.
• The molten spheres harden at 1000^oC, trapping the gases which are formed internally through catalytic action of Ferric Oxide (Fe₂O₃), or carbonaceous material present
• The gas inside the Cenospheres consists mainly of CO₂ and N₂. At room temperature, their internal pressure is about 0.2 atmospheres.
