Dal Milling Recovery & Whole Dal from Your Pulses

Dal milling turns whole pulses such as tur (pigeon pea), gram (chana) and moong into split, dehulled dal. Recovery is the share of the whole grain that comes out as clean, whole dal — the highest-value product. The rest splits into lower-value brokens and is lost as husk and powder. Better milling pushes more of the grain into whole dal.

Whole dal = whole pulse × dal recovery%, brokens = whole pulse × broken%, and husk/powder is the remainder that makes the totals add to 100%. For example 1000 kg of tur at 76% recovery gives 760 kg of whole dal, with the rest split between brokens and husk depending on how the mill is set.

A well-run mill on sound, properly conditioned grain reaches about 72–82% whole-dal recovery; below that, too much is going to brokens and husk. The exact figure depends on the pulse, grain quality and moisture, the milling method (emery rollers, plates) and how carefully the roller gap is set.

Brokens are dal pieces smaller than a half-split — they still sell, but at a lower price than whole dal, so every kilo that breaks instead of splitting cleanly cuts your return. Over-aggressive milling, dry brittle grain and a tight roller gap all raise brokens, which is why conditioning and gentle, staged milling matter.

Husk is the seed coat removed in dehulling, and powder is the fine flour lost as the cotyledons abrade against the milling surfaces. Together they are the unavoidable loss of dal milling — typically 12–20% — though sloppy milling pushes it higher. Husk and powder are usually sold as cattle feed, recovering a little value.

Pre-treating the grain loosens the husk so it slips off cleanly with less breakage. Common methods are soaking and drying, applying a little oil or water and tempering, and sun-drying — sometimes over several cycles. Well-conditioned grain dehulls in fewer, gentler passes, which lifts whole-dal recovery and cuts brokens and powder.

A roller or plate gap that is too tight grinds the grain and makes brokens and powder; too loose and the husk is not removed, so it has to go round again and abrades more. Tuning the gap to the grain size and condition — and using staged passes from coarse to fine — gives the cleanest split and the best recovery.

Yes — the whole-dal, brokens and husk model applies to any pulse you dehull and split, including tur, chana, moong, urad, masoor and peas. Just enter the whole-grain quantity and your own recovery and broken rates for that pulse, since each behaves a little differently in the mill.

Yes — enter the whole grain you will mill and the tool gives the whole dal, brokens and husk you can expect, so you know how much clean dal an order needs in raw grain, and how much by-product to sell as feed. It works for any batch size in kilograms, quintals or tonnes.

They are reliable planning figures. Real recovery shifts with pulse type, grain quality and moisture, the milling machinery and the operator's settings. Weigh the whole grain and the whole dal, brokens and husk from a few batches, plug in your own rates, and the estimate will closely match your mill.
