Construction Industry: Dolomite powder serves as a critical aggregate in concrete and asphalt mixes. Its increased hardness and density make it superior to standard limestone aggregates, providing enhanced structural integrity in buildings and infrastructure projects.
Glass Manufacturing: In glass production, dolomite provides essential calcium oxide (CaO) and magnesium oxide (MgO) components. These elements improve glass durability while magnesium specifically reduces undesired devitrification during manufacturing processes.
Paint and Coatings Industry: The material functions as an excellent extender in water-based paints, emulsions, distempers, and primers. Its high whiteness and brightness contribute to superior paint quality and light reflection properties.
Steel and Iron Industry: Dolomite acts as a flux material in blast furnace operations, helping separate metals from ores during smelting processes. It removes unwanted elements while enhancing the quality of final steel products.
Agricultural Applications: As a soil conditioner, dolomite neutralizes acidic soils and provides essential calcium and magnesium nutrients for plant growth. It improves soil structure, enhances water retention, and promotes healthy root development.
Roasted Bentonite Granules undergo specialized thermal treatment at temperatures reaching 700°C. This double-roasting process fundamentally alters the molecular structure, creating calcined, inert, and sterile granules with enhanced absorption capabilities.
The thermal transformation removes residual moisture content to less than 1%, resulting in dust-free granules with distinctive black coloration that signifies superior quality. This roasting process significantly increases absorption capacity while creating hard, crystalline particles suitable for agricultural and industrial applications.
Pesticide and Fertilizer Carrier: These granules serve as excellent carriers for pesticides, herbicides, fungicides, bio-pesticides, and bio-fertilizers. The roasting process creates inert properties that prevent contamination while extending shelf life of active ingredients.
Soil Conditioning: The granules act as natural soil activators, converting saline soils to neutral pH levels while improving soil structure and water retention capacity. They enhance dark leaf coloration, promoting photosynthesis processes essential for plant health.
Slow-Release Properties: The material releases active ingredients gradually over extended periods, reducing washout risks during heavy rainfall or water-logging conditions. This controlled release mechanism ensures sustained nutrient delivery to plants.
Water Management: Roasted bentonite granules significantly improve soil water retention, particularly beneficial in arid regions where irrigation frequency needs reduction. The enhanced absorption properties help maintain consistent moisture levels for optimal crop growth.
Chemical composition includes silica (SiO₂) minimum 40%, iron (Fe₂O₃) minimum 10%, magnesium (MgO) minimum 5%, manganese (Mn) in trace amounts, and calcium (CaO) minimum 4%. The liquid holding capacity ranges 15-20% with bulk density of 1-1.2 gm/ml.
Available mesh sizes include 10×20, 12×25, and 16×35 ASTM standards, providing flexibility for various application requirements. The granules maintain free-flowing properties even after absorbing 15-22% liquid content.
The roasted granules are bio-degradable, breaking down into smaller particles when exposed to water in field conditions. They provide natural preservation of active ingredients from direct ultraviolet radiation while maintaining non-hazardous and non-alkaline properties.
