We are one of the well-known Lime Dust Manufacturers and Suppliers based in Haridwar. We offer the clients superior quality of Lime Dust, which is available in different range of finishes. Apart from this, the Limestone, which we provide, is also available in varied thicknesses and dimensions, meeting the specific decorative demands of clients. Natural Limestone contains silica in different proportions and is largely composed of Calcite Mineral.
Grades of Limestones Offered by us :
- Cement Industry :
- Limestone containing about 45% CaO and above is usually preferred for the manufacturing of cement
- Magnesia content in the stone should ideally be less than 3%, although as high as 5% MgO is used by the industry
- The proportion of Al2O3 + Fe2O3: SiO2 should be 1:2:5. Magnesia sulphur and phosphorus are regarding as most undesirable impurities
- Iron & Steel Industry :
- Limestone is used in this industry both in the blast furnace to lower the temperature of melting and second to from calcium silicate by combining with silica of the iron ore, which comes out as slag
- For this purpose good fluxing limestone low in acid constituents such as silica, alumina, sulphur and phosphorus is required. The limestone should be dense, massive, preferably fine grained, compact and non-fretting on burning.
- Chemical Industry :
- The calcium carbide manufactures generally prefer lime containing 95% CaO (min.), not more than 3% SiO2, not exceed 2%.
- Sugar Industry :
- In sugar industry lime is used for the clarification of juice form can be beets
- Milk of lime 1% in volume of cane juice is added to pre-heated juice
- Limestone to be used in sugar industry must be high in active lime (CaO S 80% min.) must be low in iron, alumina and silica, etc.
