Stone Crushing Machine : drywasher gold gravel in sudan - We provide customers with a variety of good quality construction and mining crushing equipment, and optimize the combination of various types of equipment to meet different process needs.
Even today, some dry washers have trouble recovering gold after the top layer of dry sand has been removed, due to the moist sand and gravel below the surface.
