11.19.1 Sand And Gravel Processing

After being transported to the processing plant, the wet sand and gravel raw feed is stockpiled or emptied directly into a hopper, which typically is covered with a "grizzly" of parallel bars to screen out large cobbles and boulders. From the hopper, the material is transported to fixed or vibrating scalping screens by gravity, belt conveyors, hydraulic pump, or bucket elevators. The scalping ...

Sand Casting - an overview | ScienceDirect Topics

Sand casting is a very versatile process and can produce castings of extreme complexity in a wide range of aluminium alloys. Interest in light weighting and improvements in the technology of sand casting has driven the average weight and size of aluminium sand castings upward, with many parts weighing over 50 kg and with some parts as large as 100 m 3.
