Abstract: The aggregate processing system is a substantially closed onshore system that provides significant improvement in economy by substantially eliminating the spread of dust and dirt and/or the partial filling of the berth with sediment during the offloading of aggregate materials from a bulk cargo ship. The system includes one or more extractors that draw the bulk aggregate material from the hold(s) of the ship by entraining the aggregate in a stream of water and air. The aggregate is automatically cleaned during this step, and passes to a separating hopper where the sand and water settle out and the clean gravel is transferred to surface transport. The sand and water pass to a settling tank, where the sand is recovered for use and the water is recycled for continued use.
