Lime stone is a fine powder obtained from the processing of Limestone. It can be added to Portland cement as an addition, wither at factory to create a composite cement or at the batch plant to form a combination cement.
Limestone is a sedimentary rock primarily composed of calcium carbonate, often in the form of the mineral calcite. It can also contain dolomite (calcium-magnesium carbonate). Limestone is formed through the accumulation of marine organism remains, like shells and coral, or through chemical precipitation from seawater.

Calcined Bauxite is obtained by calcining (heating) superior grade Bauxite at high temperature (from 850 oC to 1600 oC). This removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57 % to 58 % in raw Bauxite, Calcined Bauxite has an alumina content of 82 % to 86 %. The heating is carried out in rotary kilns. Calcination is done at different temperatures ranging from 850 oC to 1600 oC depending upon the customer’s application.
We export Calcined Bauxite for various applications such as refractory bricks, abrasives, steel polishing, etc. We provide consistency in quality and availability of Calcined Bauxite at extremely competitive prices.
Applications of Calcined Bauxite:
Refractory Grade Calcined Bauxite (CB - I and CB - II Grade) : To make refractory grade, Bauxite is thermally treated at 1600 oC to produce Calcined Bauxite where the Alumina content is mostly above 82%.
Brown Fused Alumina, Proppants and Road Surfacing : To make the above grades, Bauxite is thermally treated at 1000 oC - 1200 oC to produce Calcined Bauxite where the Alumina content is anywhere between 80-88% depending on the requirement.
