Small casting clods
We use a two screen trommel to harvest castings - 1/8" and 1/4". About half the castings sort through these screens. The remainder exit the trommel in the form of small marble sized clods.
We run these clods back through, but only get a small amount of harvested material on each pass. We have varied the moisture content, but are starting to run out of ideas.
Is our experience normal?
Any ideas on solutions?
Thanks in advance.
