The raw lime stone is first screened & washed to remove undesized material and then it is fed to the vertical shaft lime kiln for preheating, calcinations & cooling operation. Here process is controlled automatically and quick lime & CO2 gas are obtained. Then quick lime is hydrated with process water in batch reactor and screened to remove lime impurity. The line slurry is then further processed to reach at designed process conditions, required in reactor for carbonation. The CO2 gas from lime kiln is cooled and washed in a vertical washer and then it is charged to the batch reactor. The required conditions are maintained in reactor to obtain different grade of precipitated calcium carbonate. This slurry is further washed, filtered and dried to get fine powder of precipitated calcium carbonate.

It is used as filler & coating pigment for premium quality paper products. PCC improves optical properties and print characterized of paper products, improves paper machine productivity & reduces paper making costs through the replacement of more expensive Pulp fiber & optical brightening agent.
PCC also finds many industrial uses, based on the ability to achieve small particle size and special crystal shapes. In rigid PVC, such as vinyl siding and fencing, PCC increases impact strength, with some of the smaller parcticles able to replace expensive impact modifiers. Nano PCCs (less than 0.1 micron in size) control viscosity and sag in automotive and construction sealants, such as PVC plastisols, polysulfides, urethanes and silicones. In paint, PCC?s unique particle shapes improve hiding and allow reductions in titanium dioxide levels.
An Effective acid neutralizer, PCC is often used in calcium-based antacid tablets and liquids. Being high in calcium content, PCC enables the formulation of high dosage calcium supplements and multi-vitamin/mineral tablets. The small particle sizes and special particle shape contribute to the development of good tasting calcium fortified.
In paint, which is another important applications, calcium carbonate has now established its self as the main extender. Fineness and particle-size distribution determine the opacity. Moreover, calcium carbonate offers interesting properties as regard to weather resistance, low abrasiveness, low electrolyte content, pH stabilizing effect, and improved anti-corrosion and rheological properties of coatings. Calcium carbonate is also important in water-based system, in which it contributes to the shortening of the drying time with - for example - important implications in road - line markings.fly ash brick making machine for sale in usa

SBM has been engaged in hematite iron ore beneficiation with its gravity separators since the mid nineties. The delivery of jigs started for the upgrading of iron ore for its utilization in a Direct Reduction Plant in Australia. Since then, various other installations with jigs for lump and fines as well as upstream separators for fines are in operation in Brazil, Australia, India and South Africa. Low grade run of mine and/or dump ores are being processed with SBM and gaustec separators as the core equipment.
This paper describes the project of a 1500 t/h beneficiation plantforhaematiticiron ore in India. The data presented show the entire project from flowsheet development to plant engineering and construction. It focuses on the specific advantages of jig application on iron ore upgrading due to the possible high gravity cuts and the easy and low cost operation. The gaustec wet high intensity magnetic separators offer high capacity in combination with unsurpassed process flexibility.
