Bagasse Ash/ Sugarcane Ash For Sale Online

Bagasse ash, also known as sugarcane ash, is the residue left after burning bagasse, the fibrous material that remains after extracting juice from sugarcane in the sugar process. Bagasse ash is primarily composed of silica, which makes up the majority of its content. It also contains small amounts of carbon, potassium, calcium, magnesium, and other trace elements.


1) Fertilizer: 

Bagasse Ash is used as an organic fertilizer and soil conditioner
with NPK in calcareous soil. Bagasse ash is rich in micronutrients like Fe, Mn, Zn and Cu and also contained sufficient amount of Ca, Mg, Na, S, K and P. Consequently, total porosity of soil, available P, S and K, Fe, Mn, Zn and Cu content in soil increases with the levels of bagasse ash application.

It also improves water solubility when mixed with other fertilizers and acts as an insecticide also.

2) Portland Cement

Because of the crystalline structure and amorphous silica content in the bagasse ash makes a suitable cement replacement material in concrete

3) Paper Industry

Bagasse is also used as a raw material for paper making because of its fibrous texture

High-grade dolomite with as low Iron and Silica content as possible is required by the glass industry. Glass grade dolomite is typified by its purity and consistency. Dolomite is a double carbonate of calcium and magnesium (CaCO3, MgCO3). The chief undesirable impurities are iron followed by chromite, manganese, vanadium and lead, all of which may cause defects in the float glass or color glass. For certain commercial colorless glass the Fe2O3 content up to 0.25% is permissible, but for pure colorless glass, Fe2O3 content of 0.04% (max) is sometimes specified.

Dolomite Powder that is suitable for making white detergent cakes. Our range is natural form of calcium magnesium carbonate that has high degree of whiteness. White colored Dolomite Powder is used in manufacturing various products like soap, detergent, paints, ceramics and many more.

Dolomite is important mineral filler for paint manufacture. It imparts several benefits to the paint. Dolomite is a hard mineral. Thus, it imparts scrub resistance to the paint. Moreover, it offers tremendous durability to the paint film against weathering. Dolomite has low oil absorption. Dolomite powder is highly dispersible and doesn’t clump together. This ensures homogeneous filler distribution in the paint which is important for uniform consistency in the paint.

Dolomite is also used in converters to maintained MgO levels in the steelmaking slags. It also acts as a slag modifier in case of slag splashing. Burnt dolomite is also used for making refractory bricks for the purpose of lining in steel melting shop. The Dolomite Powder is extensively used in Iron & Steel Industries due to its strength and compatibility in process of purifying Iron & Steel.

Water Filtration

Sand filters are used to treat drinking water in many developed and well as developing countries and they work by using a complex biological film that grows naturally on the surface of the sand. The sand itself does not perform any filtration function but acts as a substrate. However the grading of the sand in filter beds is the most crucial element of any filter plant, which will determine the functionality and longevity of the plant. They are often the preferred technology in many developing countries because of their low energy requirements and robust performance.

Following are some of standard ranges of Filter Media Sand we are generally producing:


No.Size (mm)Effective Size (mm)Hydraulic Size (mm)
10.425 – 0.850.44 – 0.540.522 – 0.64
20.50 – 1.000.522 – 0.640.62 – 0.76
30.60 – 1.180.62 – 0.760.73 – 0.89
40.71 – 1.400.73 – 0.890.87 – 1.07
50.85 – 1.700.87 – 1.071.03 – 1.254
61.00 – 2.001.03 – 1.2541.224 – 1.50

81.40 – 2.801.40 – 1.7051.62 – 1.98

Salient Features:

  • The material is 100 % Silica Quartz with very minor impurities.
  • The specific gravity is higher than required i.e. 2.63 as against 2.5 required.
  • Higher weight does not allow the sand to be washed away during back washing.
  • Hardness coefficient is around 7.5 as compared to the requirement of 4.5, which prevents abrasion during the back washing process, and this will prevent change.
  • The shape of particle is cubical which makes is more efficient for filtration due to better interlocking process.
  • The grading of material is very consistent and lies in the middle of the range allowed as per specifications.

We have the capability to produce and supply any grading according to the project’s unique filtration requirement. In the past we have produced sand and gravel with varying grading for several different projects.
