Standard Size / PSD
Reference phosphate rock particle size distribution.
The following size profile is taken from the old product file and presented for buyer handling, feeding, dust and logistics review.
| Size Fraction | Result % | Operational Note |
|---|---|---|
| + 4.5 mm | 0 to 2 | Controlled oversize to protect hopper feeding stability. |
| -4.5 to -0.16 mm | 70 to 80 | Primary sized fraction for consistent handling and processing. |
| -0.16 to +0.08 mm | 10 to 15 | Fine fraction managed to limit dust and handling losses. |
| -0.08 to +0.05 mm | 3 to 5 | Micro-fines controlled for shipping and discharge behavior. |
| -0.05 mm | 5 to 8 | Ultra-fines monitored to protect moisture and dust performance. |
PSD should be confirmed against the buyer’s process and discharge system. Powder and lumps may require different acceptance windows depending on application and packing method.

FAQ
Frequently asked questions about phosphate rock specifications.
What P₂O₅ grades can TAS Flowrance discuss?
TAS Flowrance can discuss Phosphate 21 to Phosphate 30, subject to availability, buyer requirement, updated analysis and quotation confirmation.
Are the specification values final?
No. The values are reference data for buyer screening. Final contractual values must be confirmed by COA, accepted tolerances and quotation documents.
Why was Na₂O marked as COA confirmation?
The old technical file showed an inconsistent Na₂O range. For professional buyer trust, the final value should be confirmed by updated COA before offer.
What is the reference PSD from the old file?
The main fraction is -4.5 to -0.16 mm at 70 to 80%, with controlled oversize, fines, micro-fines and ultra-fines for handling review.
What should buyers send for a technical quotation?
Send target P₂O₅, form, PSD requirement, quantity, packing, destination port, Incoterm, application and required documents.
Can powder and lumps have different specifications?
Yes. Powder and lumps may need different size, handling, moisture and packing review depending on the buyer’s process and shipment conditions.
