Fine cleaning · Model MDJY

Grain Length Grader

Removes broken, shrivelled and diseased kernels by length alone.

  • 60+ years manufacturing
  • 10–500 t/d capacity range
  • 100+ patents
  • Turnkey commissioning

What it does

An indent cylinder grades by kernel length, which no screen can do. It pulls out broken grains, ergot-adjacent shrivelled kernels and light diseased grain that would otherwise inflate your ash and downgrade your flour colour.

Technical parameters

Nominal values at standard conditions. Confirm final specification on the order drawing.

Selection guidance

Essential for seed production and for any market that grades visually. For plain commercial flour milling it is optional — but it pays back quickly on high-value wheat.

Maintenance

Indent pockets wear at the leading edge; re-cut or replace cylinders every 3–5 seasons depending on tonnage.

Frequently asked questions

Straight answers to the questions engineers and mill owners actually ask us during plant sizing. If your case is not covered, send the wheat specification and your target tonnage.

What is the difference between the two separation figures?
Broken-in-whole is how much broken grain remains in the accepted stream (lower is better). Whole-in-broken is how much good grain is lost to the reject stream (also lower is better). Together they define the machine's efficiency.
