Had a customer send in these pictures to share with everyone on how he loads & unloads his dry wash towers with wood chips.
He loads the wood chips in disposable paint strainers from a hardware store (ie. Home Depot) and then shoves the load up into the tower one bag at a time. When it's time to change them out, they come out much quicker & cleaner than if it was just saw dust.
I threw the pictures into a sort of tutorial of sorts to show how he does it.
