Ironsand - Wikipedia
Deposits of iron ore were scarce in Japan, so, around the 8th century, iron-making technology developed with the use of ironsand as the raw ingredient. Because of the loose nature of the sand it was difficult to smelt in a normal bloomery, or to use in a blast furnace to make pig iron, so the Japanese developed an open-topped bloomery called a tatara. The tatara was built with a low,Sand Making Machine,Vertical Shaft Impact Crusher,VSI,,VI Series Vertical Shaft Impact Crusher (sand making machine) is Yifan Machinery introduction of Germany advanced technology R & D and production efficiency iron ore crusher. High performance sand making equipment with international advanced level, its performance plays an irreplaceable role in the various ore fine crushing equipment. VI Series Vertical Shaft ImpactSand Making Machine | VSI6X Sand Maker Supplier,VSI6X Sand Making Machine has two feed modes – “feed at center” and “feed at center & sides”. As for “feed at center”, materials at the feed hopper firstly pass through the central hole into the high-speed spinning rotor. Next, materials hit the surrounding vortex material linerinside the vortex chamber together. Finally, finished products are discharged from the bottom discharge opening.
