Fertilizer-grade bentonite granules are not the same as general-purpose granules. The fertilizer industry has specific, non-negotiable requirements: granule hardness sufficient to survive auger mixing without crushing, moisture content controlled to prevent caking in 50 kg bags during warehouse storage, dust level below 2% to keep blending lines clean, and mesh consistency tight enough that the NPK formula does not drift out of specification.
At our Bhavnagar facility, fertilizer-grade production is a dedicated product line with separate raw material selection โ we use bentonite from mine faces with proven low grit content because grit (silica sand particles) accelerates wear on fertilizer plant blending equipment. The granules are double-screened to remove undersize and oversize, then tested for crush strength before packing.
We supply fertilizer-grade granules to NPK plants across Gujarat, Rajasthan, Madhya Pradesh, and Maharashtra. Several plants have been repeat customers since 2021, receiving scheduled truckload dispatches aligned to their monthly production calendar.

What Makes Fertilizer-Grade Different from Standard Granules
A fertilizer blending line is a high-throughput continuous process. Granules that break during mixing create dust that clogs filters, drifts onto the factory floor, and alters the NPK ratio of the blended product. Fertilizer-grade bentonite must survive the mixer, the conveyor, the bagging hopper, and warehouse stacking โ all without significant degradation. Standard agriculture-grade granules, which may be adequate for field broadcasting, often fail under the mechanical stress of a blending line.
Our fertilizer-grade granules are produced to tighter specifications: narrower mesh tolerance (ยฑ1 mm versus ยฑ2 mm for standard grade), lower moisture ceiling (10% versus 12%), and measured crush strength (above 2 kg per granule). These three parameters are tested for every production batch and recorded on the certificate of analysis provided with dispatch.
Scheduled Supply for Continuous Production
Fertilizer plants run continuous production campaigns โ typically 20โ25 days per month, 10โ11 months per year. They cannot afford to run out of bentonite on day 18 of a 20-day campaign because a truck was delayed. Our scheduled supply model addresses this: contracted monthly volume, fixed dispatch dates (e.g., the 1st, 10th, and 20th of each month), and buffer stock reserved for the contracted buyer.
For new buyers, we recommend starting with a trial truckload (10โ15 MT) to validate granule performance on your specific blending line. Once the trial is successful and specifications are agreed, we set up a quarterly or annual supply contract with fixed pricing and scheduled dispatches.

Can you match the specification from my current bentonite supplier?
Yes. Send us your current supplier's specification sheet or a sample of the material you are currently using. We will analyse mesh distribution, moisture, crush strength, and bulk density, and confirm whether our standard fertilizer grade matches or whether adjustments are needed.
What testing do you provide with fertilizer-grade shipments?
Each truckload includes a certificate of analysis showing: mesh distribution (% retained on 8 mesh, % passing 16 mesh), moisture content, bulk density, and crush strength. Additional tests (CEC, pH, swell index) can be included if specified in the supply contract.
Do you offer annual rate contracts for large fertilizer plants?
Yes. For buyers with monthly offtake above 100 MT, we offer annual rate contracts with quarterly price reviews. This gives the plant procurement team budget certainty while allowing price adjustments if raw material or fuel costs change significantly.
