Where to Install a Grain Cleaner Before Truck Loading

Keep useful grain moving toward the truck

When stored grain needs cleaning before delivery, fit the cleaner to both the unwanted material and the route out of the bin. The useful result is a cleaner grain stream headed to the truck, with removed material collected separately. Start with a bin-to-truck sketch—not just an open spot where a machine might fit.

Draw the route, including the material you remove

Trace the existing route from the bin outlet through each auger or conveyor to the truck. Mark the proposed cleaning point, then add:

– Where grain enters the cleaner and how its feed will be controlled.
– Where cleaned grain leaves and how it reaches the truck.
– Where removed material will be collected and taken away.
– The inlet and discharge heights and connections that need to match.

The ADS manual calls for feed and discharge conveyors arranged to provide continuous separation. That makes both sides of the cleaner important: getting grain into it is only half the fit.

Keep the removed-material route separate from the cleaned-grain route. On ADS models with a cyclone dust collector, dust, chaff and other waste leave through dedicated waste trays. Include those collection points in the sketch rather than treating them as leftover space.

Choose the separation, then check the loading rate

Match the cleaner to what needs to leave the grain:

– Size-different dirt and debris: VDSC screening separates by size and removes debris, including dust and small impurities. It can work alone or in a cleaning line.
– Lighter unwanted material: ADS or ADS-CDC separates material by its response to airflow, directing it into separate fractions while retaining useful grain.

Next, write your required loading rate beside the route. Compare it with the rate that produces the needed separation—not simply a listed primary-cleaning capacity. The ADS operating manual ties usable feed rate to cleaning or grading quality and notes that results vary by crop. Metra’s operating experience also shows that heavily contaminated grain may need a lower feed rate.

If the rate needed for good cleaning is below your usual loadout rate, account for that difference before scheduling the load. A faster conveyor does not make the cleaner separate well at that same rate.

Check the space around and under the cleaner

Use the proposed location to check support, dust handling, power and service access—not just cabinet dimensions.

For VDSC, the installation manual requires a firm base, secure bolting and all machine bases on the same level surface.

For ADS, the manual recommends at least 1,200 mm, or 4 feet, of free space on all sides for maintenance. It also requires a qualified electrician to connect the power supply. Confirm the selected machine’s electrical requirements before arranging that connection.

Location also affects the airflow configuration. ADS without CDC is specified for outdoor use because dust exits with the air; it still needs the weather protection required by its manual. ADS-CDC includes a cyclone dust collector. Account for that configuration and its waste collection when checking the available space.

Bring the sketch and the cleaning job together

Your sketch should now show the grain’s path, the removed-material destination, the required loading rate and the site constraints. Metra can use that information to help fit equipment and settings to your grain and existing setup.

You do not need to choose a model first. For help removing the unwanted material while retaining useful grain for delivery, arrange a free test of your own grain with the Metra team at [info@graincleaner.com](mailto:info@graincleaner.com). The team can demonstrate separation, evaluate the cleaned and removed fractions, and recommend suitable equipment and settings. Your manager will confirm shipping arrangements and any associated costs before you send the sample.
