Bhavnagar district produces over 60% of India's bentonite. When you buy bentonite granules from a Bhavnagar manufacturer, you are buying at the source — closer to the mines, closer to the processing expertise, and closer to the transport corridors that move bentonite across India and to export ports. Radhe Enterprise has manufactured bentonite granules at our Thordi, Bhavnagar facility since 2020, producing Red Ball, Black Ball, Brown, Fertilizer-grade, Organic, Humic Ball, Seaweed Ball, and Absorbent granules.
The bentonite belt of Bhavnagar exists because of geology: a thick sequence of sedimentary clays deposited during the Tertiary period, altered over millions of years to calcium bentonite by groundwater percolation and volcanic ash weathering. This geological history created bentonite deposits with a range of properties — from high-swelling calcium bentonite (preferred for drilling and foundry) to calcium bentonite with high iron content (preferred for fertilizer and agriculture). Our factory draws from multiple mine faces to produce the full range of bentonite granule grades.

Why Bhavnagar Is India's Bentonite Capital
Bhavnagar district processes over 2 million tonnes of bentonite annually through more than 50 processing units ranging from small-scale grinder operations to fully integrated manufacturer-exporters. The district's dominance comes from three factors: geology (the bentonite seam runs thick and accessible within 50 km of the city), infrastructure (NH-8A connects Bhavnagar to Ahmedabad and the national highway network, while Mundra, Kandla, and Pipavav ports are within 3–4 hours for export), and labour (multi-generational expertise in bentonite mining, processing, and trading — workers who can judge clay quality by feel and colour).
For industrial buyers, this concentration of bentonite activity creates a competitive, transparent market. Buyers can visit multiple factories in a single day, compare material quality and pricing directly, and make informed procurement decisions without relying solely on trader intermediaries. Radhe Enterprise welcomes factory visits — we are located in Thordi village, approximately 35 minutes from Bhavnagar city centre via NH-8A.
Choosing the Right Bentonite Granule for Your Application
The bentonite granule that works perfectly for a fertilizer plant (hard granules, 8–16 mesh, moderate swell) will underperform in a foundry (needs higher swell, Black Ball preferred) and be completely wrong for a cat litter manufacturer (needs 1–4 mm granules, low dust, specific absorption profile). The most expensive mistake a new bentonite buyer makes is ordering "bentonite granules" without specifying the application — and receiving a grade that is technically bentonite but practically unusable for their process.
Our recommendation: start by identifying your application from the list below, then navigate to the dedicated product page for detailed specifications, pricing guidance, and buyer-specific FAQs. If your application does not match any listed category, contact our team with a description of your process and we will recommend the appropriate grade.
Bhavnagar Factory Visit — What to Expect
A factory visit to our Thordi facility typically takes 1–2 hours and covers: raw material storage (see the different bentonite grades segregated by mine source), the granulation line (pan granulators in operation, screening stations, moisture monitoring), the QC lab (moisture balance, sieve shaker, swell index testing, sample retention shelves), finished goods warehouse (bagged stock ready for dispatch, jumbo bags, container loading area), and a discussion with our production manager about your specific requirements.
We recommend factory visits for buyers planning annual contracts above 50 MT per month. Seeing the operation in person gives you confidence in quality control, production capacity, and the team's technical capability. To schedule a visit, contact us with your preferred date and we will confirm availability.
Pan Granulation — The Core Process
All our granules — Red Ball, Black Ball, Brown, and specialty grades — are produced on pan granulators. The pan granulator is an inclined rotating disc where fine bentonite powder is fed continuously while water is sprayed onto the material. The tumbling action causes the wetted particles to roll against each other, gradually building spherical granules like snowballs. When the granules reach target size (typically 2–4 mm for standard 8–16 mesh), they overflow the pan rim and are conveyed to the drying stage.
The skill in pan granulation lies in controlling three variables: pan angle and speed (determining residence time and granule trajectory), moisture content (too low → no granulation; too high → mud balls), and feed rate (matching the pan's capacity). Our operators adjust these variables based on the specific bentonite grade being processed — Black Ball granulates differently from Red Ball because of different clay plasticity. This grade-specific process knowledge is developed through years of experience and is one of the capabilities that distinguishes a reliable granule supplier from an inconsistent one.

Frequently Asked Questions
What is the difference between Red Ball, Black Ball, and Brown bentonite granules?
The colour difference reflects iron oxide and organic content in the source clay. Red Ball (8–12% Fe₂O₃) is used in fertilizer and agriculture. Black Ball (high organic content, swell index 15–25 ml/2g) is used in foundry and drilling. Brown granules (moderate organic content, swell index 8–15 ml/2g) are the cost-effective choice for general agriculture and basic fertilizer binding. Each colour variant serves a different performance tier and price point.
Can I buy mixed grades in a single truckload?
Yes. For buyers serving multiple customer segments (e.g., an agro-input distributor who supplies both fertilizer manufacturers and direct farmers), we can load mixed products in a single truck. The minimum per product is typically 2–3 MT within a mixed load.
How far is your factory from Bhavnagar city?
Our Thordi facility is approximately 25 km from Bhavnagar city centre, accessible via NH-8A. Driving time is approximately 35–40 minutes from the city. Clear signboards mark the route from Bhavnagar to Thordi village.
Do you offer annual supply contracts for large buyers?
Yes. For buyers with monthly offtake above 50 MT, we offer annual supply contracts with quarterly price reviews, scheduled monthly dispatches, and reserved buffer stock. Annual contracts provide price stability for procurement budgeting and supply security during peak demand seasons.
Can I get custom mesh sizes for my specific application?
Yes. While standard production is 8–16 mesh, we can produce custom mesh ranges including 8–30 (finer granules for better distribution), 4–8 (coarser for slow-release applications), and 16–30 (for blends requiring finer material). Custom mesh orders of 10 MT or more can be scheduled with 5–7 working days lead time. Custom mesh may carry a small premium depending on the yield loss at the screening stage.
