Archmides screw used in silo storage
In 2019 and 2020, Landustry supplied ESI Eurosilo in Purmerend, The Netherlands with a total of 35 no. dangerous-looking screws, i.e. screw conveyors. Striking of the screws is the notched flight and the material used, in this case Creusabro 4800. Creusabro is a high performance wear resistant steel.
The screw conveyors are used in coal and gypsum silo storage, for mixing and evenly distributing the material. These applications each require a specific external cut. The screws ensure an optimal distribution of the material stored in the silo.
After the first order for coal silos in China, an identical order followed for Turkey, and Germany where the screws are used in gypsum silo storage.
