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.

Gold Wash Plant for Sale - 911Metallurgist
Using a gold wash plant, exposed gold-bearing gravels are mined using a bulldozer that pushes and stockpiles the gravel near a wash plant.The stockpiled gold-bearing gravel is then fed into the wash plant by a front-end loader or large backhoe. This practice promotes equipment efficiency by allowing the bulldozer to continue mining while the loader or backhoe feeds the wash plant at a steady rate.
