My sales and R&D want to launch a product that is a coarse fiber. Some of the pieces are up to .5 inches in length. (everything else we make is ground to powder) Can anyone think of a way to sieve for foreign material? The raw material is an agricultural product (dried orange peel). We do currently metal detect down to 2.0mm, but what about anything else? Any experience with this? I added a picture of the proposed product.
