Sand Screws and Cyclones: Which is Best for Washing Sand?
Sand screws handle irregular feed particularly well. You can feed a properly sized screw 30 tons per hour or 400 tons per hour and the screw will keep running like nothing has changed. Cyclones are much more sensitive to overfeed situations. Cyclones are also particularly sensitive to oversize. If an oversize particle enters a cyclone, it only ...
