Industrial Minerals for Edible Oil Refining and Base Oil Purification - Supplier and Exporter from India
Shri Balaji Mines and Minerals supplies a comprehensive range of clay minerals and adsorbent materials to edible oil refineries, base oil processors, lubricant re-refiners, biodiesel producers and industrial oil treatment facilities worldwide. Our mineral portfolio – including Activated Bleaching Earth, Natural Fuller’s Earth and Silica Sand – serves the critical oil purification, decolorization, degumming and aromatic removal stages of both edible oil refining and mineral or base oil processing operations globally.
Whether your refinery uses the standard contact mixing and filtration method for edible oil bleaching, or the percolation method for base oil purification and aromatic removal – we supply the right mineral adsorbent in the right grade and form for your specific oil type, process configuration and quality specification.
We export on FOB and CIF basis from Mundra and Kandla ports, serving buyers in Malaysia, Indonesia, Vietnam, Bangladesh, Egypt, Ghana, Nigeria, UAE, Saudi Arabia and other global markets.
Minerals We Supply for Oil Refining and Purification
Activated Bleaching Earth - Bleaching Clay / Acid Activated Bentonite
In edible oil refining, Activated Bleaching Earth works through the contact method - mixed with warm degummed oil under vacuum conditions and subsequently removed by pressure leaf filter or plate-and-frame filtration. Acid-activated clays are the primary adsorbent used in industrial edible oil bleaching.
In base oil and mineral oil processing, Activated Bleaching Earth and Acid Activated Bentonite are used via both the contact method and the percolation method - removing aromatic hydrocarbons, polar impurities, colour bodies, oxidation products, acids and surfactants from Group I, Group II and Group III base oils, lubricating oils, hydraulic oils, transformer oils and industrial mineral oils.
Edible Oil Applications:
Palm oil, palm kernel oil, soybean oil, sunflower oil, rapeseed oil, canola oil, cottonseed oil, groundnut oil, coconut oil, rice bran oil and all other vegetable oils and animal fats
Base Oil and Mineral Oil Applications:
Group II base oil purification, lubricant re-refining, transformer oil treatment, hydraulic oil purification, used oil reclamation and industrial mineral oil processing
We supply Activated Bleaching Earth in multiple activity grades - high activity, standard activity and low oil retention - in 200 mesh powder and granule form.
Natural Fuller's Earth - Oil Refining and Percolation Grade
Fuller's Earth has a high capacity for removing colors from oils whether of animal, vegetable or mineral origin - used in both the contact process and the percolation process for treating oils.
In edible oil refining, Natural Fuller's Earth is used as a mild natural bleaching agent for oils with lower pigment loads where acid activated earth is not required, and as a pre-bleaching step before activated earth treatment to extend the life of the more expensive activated grade.
In base oil and mineral oil processing using the percolation method - Natural Fuller's Earth is packed into percolation columns or fixed-bed systems through which the oil flows by gravity or pressure. Fuller's Earth is used for acid removal and surfactant removal in refineries and transformer repair shops - removing acids, oxidation products, surfactants, additives, soaps, colours and other soluble contaminants from lubricating oils, hydraulic oil, insulating oil and mineral spirits.
The percolation method is specifically preferred for base oil processing where the oil is passed through a packed bed of Fuller's Earth for continuous, low-labour purification - removing aromatic content, polar impurities and colour bodies from virgin Group II base oils and re-refined lubricant base stocks.
We supply Natural Fuller's Earth in multiple grades - edible oil refining grade, industrial percolation grade and general adsorptive grade - in lumps and powder form (200 mesh and 325 mesh).
Silica Sand - Filtration Aid and Percolation Media
In oil purification using the percolation method, Silica Sand is used in combination with Fuller's Earth and Activated Clay as a filtration support layer and flow-distribution medium in packed percolation columns - improving flow uniformity, preventing clay compaction and extending the operational life of the clay bed. This combined use of Silica Sand + Fuller's Earth + Activated Clay in percolation columns is a well-established industrial practice in base oil purification, used oil re-refining and mineral oil processing globally.
Synthetic amorphous silica is used in wet bleaching to selectively remove phosphatides, trace metals and other impurities from edible oils - making silica a complementary adsorbent alongside bleaching earth in advanced two-stage edible oil refining systems.
Silica Sand is also used in edible oil refinery filtration systems as a precoat filtration aid alongside diatomaceous earth - improving filtration efficiency and clarity of the refined oil after the bleaching stage.
We supply high-purity Silica Sand in multiple purity grades and controlled size specifications - including mesh size ranges and MM fractions suited to percolation column packing and filtration aid applications.
