Ceramic filter disc are vacuum-disc filters comprised of sintered alumina sector plates with uniform micro-pores. The micro-pores create suction through capillary action and once wetted, the filter medium allows only liquid to pass through during the filtering process. A filter cake forms on the surface of the disc and is removed by a …

The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium- to high-grade (+62% Fe) and are directly used in blast furnace and in direct-reduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and …

Wash water is generated as a by-product of ready mixed concrete production. Reuse of the water as mixture water is limited, in practice, by the negative material performance impacts associated with the water chemistry and suspended solids (i.e. hydrating binder phases and very fine aggregate); the effects are intensified with increasing content of suspended …
