We are leading manufacturer , Exporter, Supplier of Rice Husk Ash.

Rice milling generates a by product know as husk . This surrounds the paddy grain. During milling of paddy about 78 % of weight is received as rice , broken rice and bran .Rest 22 % of the weight of paddy is received as husk . This husk is used as fuel in the rice mills to generate steam for the parboiling process . This husk contains about 75 % organic volatile matter and the balance 25 % of the weight of this husk is converted into ash during the firing process , is known as rice husk ash ( RHA ). This RHA in turn contains around 85 % - 90 % amorphous silica. So for every 1000 kgs of paddy milled , about 220 kgs ( 22 % ) of husk is produced , and when this husk is burnt in the boilers , about 55 kgs ( 25 % ) of RHA is generated.

India is a major rice producing country , and the husk generated during milling is mostly used as a fuel in the boilers for processing paddy , producing energy through direct combustion and / or by gasification . About 20 million tones of RHA is produced annually. This RHA is a great environment threat causing damage to the land and the surrounding area in which it is dumped. Lots of ways are being thought of for disposing them by making commercial use of this RHA. The particle size of the cement is about 35 - 45 microns . There may be formation of void in the concrete mixes , if curing is not done in properly . This reduces the strength and quality of the concrete . Our product ? Silpozz ? which is made out of this RHA is finer than cement having very small particle size of 25 microns , so much so that it fills the interstices in between the cement in the aggregate. That is where the strength and density comes from. And that is why it can reduce the amount of cement in the concrete mix .

RHA is a good super-pozzolans . Silpozz can be used in a big way to make special concrete mixes . There is a growing demand for fine amorphous silica in the production of special cement and concrete mixes ,high performance concrete ,high strength, low permeability concrete, for use in bridges, marine environments , nuclear power plants etc. This market is currently filled by silica fume or micro silica , being imported from Norway, China and also from Burma . Due to limited supply of silica fumes in India and the demand being high the price of silica fume has risen to as much as US$ / ton in India.

Rice husk ash is used in the production of special high-quality steel with low thermal conductivity and density. ZRSH is added to the heat-insulating mixture to cover the mirror of the metallurgical ladle, which additionally ensures compliance with the temperature regime of continuous casting processes. Ash is used as a filler in polymers and rubbers for the production of car tires, as an adsorbent for heavy metals for wastewater treatment. In the pharmaceutical industry, ash is added to stabilize emulsions, as an agent, thickener and suspending gel in the preparation of semi-solid products, in perfumery, RHA is added as a filler for toothpastes and creams.

Equally important is the use of rice husk ash as a natural source of high performance amorphous silica.

Fly ash is a by-product of coal burning at the utility plants. As coal is burned, non-combustible mineral impurities in coal evaporate andcondense into tiny particles of glass, almost totally spherical inshape. The individual particles are very small, like talcum powderand are carried up and out of the boiler in the flow of exhaust gasesleaving the boiler after the coal is consumed.

The fly ash particlesare removed from the exhaust stream in bag houses or electrostatic precipitators and then stored for later shipment

The difference between fly ash and Portland cement becomes apparentunder a microscope. Fly ash particles are almost totally spherical inshape allowing them to flow and blend freely in mixture. Thatcapability is one of the properties making fly ash adesirable admixture of concrete.
