Dolomite Powder
Manufacturers in India
Finely milled, high-purity mineral filler from a trusted dolomite powder manufacturer in India.
Unmatched Purity
& Performance
Dolomite powder is a finely ground mineral filler produced from dolomite rock, a naturally occurring double carbonate of calcium and magnesium with the chemical formula CaMg(CO3)2. It forms in sedimentary rock deposits over millions of years and is mined much like limestone, though its added magnesium content sets it apart both chemically and physically. Once crushed and milled, dolomite powder is valued for its natural whiteness, chemical stability, moderate hardness and low oil absorption, properties that make it one of the most widely used functional fillers in Indian industry.
It works as an extender, an opacifying agent and a cost-effective substitute for higher-priced minerals such as titanium dioxide or pure calcium carbonate. Because dolomite carries both calcium and magnesium carbonate, it is harder and more weather-resistant than plain calcium carbonate, which is why formulators across paints, plastics, rubber, glass, ceramics, agriculture and construction continue to specify it. As one of the established dolomite powder manufacturers in India, Vrindavan Minerals processes raw rock into paint grade, plastic grade and industrial grade powder entirely in-house, handling everything from small trial quantities to bulk jumbo bag orders.
High Weatherability
Exceptional resistance to weathering and atmospheric conditions, making it ideal for exterior applications.
Aravalli Mineral Belt
Direct proximity to Rajasthan's dolomite reserves keeps our sourcing and quality control tight.
Why Udaipur & Rajasthan
Rajasthan is home to some of India's most significant dolomite reserves, particularly across the Aravalli belt that runs through Udaipur, Rajsamand and neighbouring districts. This geological advantage is a major reason why dolomite powder manufacturers in Rajasthan are concentrated in and around Udaipur, giving the region direct access to high-purity raw material without the added freight cost of transporting rock over long distances.
Being based here as a dolomite powder manufacturer in Udaipur gives us a practical edge. Raw rock reaches our processing unit quickly, quality can be checked closer to the source, and we maintain tighter control over whiteness and chemical consistency than units that depend on rock sourced from multiple, distant quarries. Vrindavan Minerals runs its own crushing, grinding and screening facility rather than operating purely as a trading intermediary, which lets us function as one of the dependable dolomite powder suppliers in India for paint, plastic, rubber, glass, ceramic, agriculture and construction buyers, with shorter dispatch timelines across Rajasthan, Gujarat, Madhya Pradesh and beyond.
How Dolomite Powder Is Processed
Turning raw dolomite rock into a consistent, application-ready powder involves several controlled stages. Exact parameters vary by grade and mesh requirement, but the core manufacturing process generally follows four steps from mine to finished bag.
Mining & Selection
Dolomite boulders are extracted from Rajasthan's Aravalli belt and sorted to remove low-purity or discoloured rock before it enters processing.
Crushing & Drying
Selected rock is crushed into smaller chips and dried to remove surface moisture, which is essential for stable whiteness and preventing lump formation.
Grinding & Mesh Grading
Dried material is ground in ball mills or micronizers and screened to the required mesh size, from coarse 100 mesh to fine 1250 mesh.
Testing & Packing
Each batch is tested for whiteness, chemical composition and moisture before being packed into moisture-resistant bags for dispatch.
Key Properties & Grades
Not all dolomite powder is milled to the same specification, and choosing the right grade has a direct impact on how it performs in your formulation. Coarser mesh sizes such as 100 and 300 are typically used in agriculture, construction and lower-cost industrial fillers, while finer grades from 500 mesh up to 1250 mesh are preferred in paints, plastics and rubber compounding where smooth dispersion and surface finish matter more. Whiteness requirements follow a similar pattern: paint and plastic formulators generally look for 90% or higher so the filler does not interfere with pigment shades, while agriculture and construction uses are less sensitive to this figure. The tables below summarise the physical and chemical parameters we test on every batch of industrial grade dolomite powder, so you can match mesh size, whiteness and chemical composition to your process before placing an order.

Industrial Applications
Dolomite powder's combination of whiteness, hardness and chemical stability makes it a functional filler across a wide set of industries. Paint formulators use Dolomite Powder for Paint as a partial substitute for titanium dioxide, improving scrub resistance and opacity in wall putty and decorative coatings. Plastic and PVC processors use Dolomite Powder for PVC to add rigidity and dimensional stability while reducing resin consumption. Rubber compounders rely on it to reinforce mechanical properties, glass manufacturers use Dolomite Powder for Glass as a fluxing agent, and ceramic producers add it to glazes and bodies for improved thermal stability. In agriculture, Dolomite Powder for Agriculture is applied as an economical soil conditioner.
Paints & Putty
Our Paint Grade Dolomite Powder acts as a superb extender. Improves scrub resistance, reduces TiO2 consumption, and creates brilliant white wall putties.
Plastics & PVC

Rubber & Tyres
Used as a reinforcing filler in rubber compounding, dolomite powder improves mechanical strength and helps reduce material cost in tyres, seals, mats and moulded components.
Glass Manufacturing
Dolomite Powder for Glass manufacturing acts as a fluxing agent, lowering the melting temperature of the raw batch while improving structural durability and clarity in the final glass.
Ceramics & Glazes
In ceramic bodies and glazes, dolomite powder acts as a flux and whitening agent, improving thermal shock resistance and surface finish in tiles and glazed ceramic products.
Agriculture
As a soil conditioner, Dolomite Powder for Agriculture neutralizes acidic soils and supplies vital calcium and magnesium nutrients that support healthier crop growth.
Quality Factors To Check
Before finalising an order, ask any dolomite powder supplier for a current test certificate covering four essentials: whiteness percentage, chemical composition (CaO, MgO and SiO2), moisture content, and mesh or particle size distribution. These figures determine how consistently the powder will disperse, how much it will affect the final colour of your product, and how it behaves during processing.
It is equally important to check batch-to-batch consistency rather than relying on a single sample report. Ask whether the supplier tests every dispatch or only periodic batches, and confirm packaging details, since moisture-resistant HDPE bags with proper liners protect the powder during transit, especially over long distances or humid conditions. Finally, check whether the manufacturer can support both small trial orders and recurring bulk volumes, so you are not forced to switch suppliers as your requirement scales.
Choosing A Manufacturer
India has no shortage of dolomite powder manufacturers, but not all of them control the complete process from raw rock to finished mesh. Many operate as traders who buy semi-processed material and simply repack it, which makes it harder for them to guarantee mesh accuracy or chemical consistency order after order. Working directly with a manufacturer that mines, crushes, mills and screens its own material generally means tighter quality control and more transparent pricing on bulk volumes.
When evaluating dolomite powder manufacturers in India, look for a track record of pan-India dispatch, clear batch documentation, and the flexibility to produce custom mesh sizes rather than a fixed catalogue. Vrindavan Minerals combines in-house processing with batch-wise testing from our Udaipur facility, giving buyers a dependable dolomite powder manufacturer in Rajasthan to rely on for consistent grade, timely dispatch and responsive technical support.
Dolomite powder remains one of the most versatile mineral fillers used across Indian manufacturing, from paints and PVC to rubber, glass, ceramics, agriculture and construction. Getting consistent results depends less on the mineral itself and more on choosing a supplier who documents whiteness, chemical composition and mesh size on every batch. As dolomite powder manufacturers in Udaipur, Rajasthan, Vrindavan Minerals combines direct access to raw material with in-house processing and testing, so buyers across India can source paint grade, plastic grade and industrial grade dolomite powder with confidence.
