Flour And Grain Mills

In a flour mill the roll gap gets the attention, but the flour specification is largely decided before the wheat reaches the first break: by how much stone, dust and surface dirt the cleaning section removed.

Reality On Site

Pain Points We Hear

  • Stones and glass reach the rolls and cause damage that stops the mill mid shift.
  • Surface dirt raises the ash figure and the flour misses its grade.
  • Insect fragments and microbe counts fail a customer audit.
  • The cleaning section throttles a mill that was bought for a higher capacity.
  • Durum and oats need more intensive scouring than the standard rotor allows.
Requirements

What The Plant Actually Needs

  • A destoner rated above the mill capacity for the wheat actually bought
  • Horizontal scouring with aspiration at the discharge
  • Multi deck sieving with inlet aspiration to reduce sieve load
  • Conveying that matches the section capacity in both directions
  • Storage silos that hold wheat at a stable moisture before milling
Process Route

The Flour And Grain Mills Process Route

IntakeWheat received, weighed and conveyed to the raw wheat silos.
Pre CleaningCoarse and light impurities removed before storage.
DestoningMTSD destoner separates stones, pebbles and glass by density.
First ScouringHorizontal scourer removes adhering dust, sand and earth lumps.
TemperingWheat rests at controlled moisture before the second cleaning.
Second ScouringSecond pass improves sanitation and prepares the kernel for milling.
Sifting And GradingMulti deck sieve and plansifter separate the fractions.
PackingFlour bagged on quantitative scales or in doypack pouches for retail.
Scenarios

Typical Project Scenarios

  • New cleaning section for a wheat mill
  • Durum line needing intensive scouring
  • Maize or rye cleaning ahead of milling
  • Wheat storage added in front of an existing mill
FAQ

Flour And Grain Mills Questions

How much cleaning capacity should I install?

Size the cleaning section above the milling capacity. A TTS-400 scourer at 18 TPH in front of a smaller mill keeps working when the wheat is dirtier than usual.

Does scouring damage the kernel?

Scouring works on the surface. Rotor and screen jacket designs are selected for the crop, with intensive versions for durum and oats.

Can the destoner handle maize?

Yes, at up to 16.5 t/h on corn and maize. The same machine also handles rye, rice and soybeans.

Do you supply wheat storage as well?

Yes. Galvanized silos for flour milling are part of the same project scope, including the conveying between silo and mill.
