Don't know what size screen opening you have or how many TPH you want/need. If it's absolutely dry, yes, you can. If there's ANY moisture along with silt or dirt in it the screens will blind. Being filter media it won't matter if it's wet, which I think won't be clean enough without a wash screen and a sand screw to remove all impurities. If the customer doesn't want to pay for the water then weigh a wet sample, dry it, weigh it, and deduct the weight of the water from your price.
