Official Grain Dockage Sieves - Seedburo

Sieves should be replaced when the perforations show wear, to maintain accurate results. Slotted sieves used in sizing barley and oats need to be replaced regularly since these grains are highly abrasive. A worn sieve lets too much material pass through, giving inaccurate results. Damaged or dented sieves should always be replaced.
