SILO FOR SEPARATING CRUSHED SAND FROM POWDERY MATERIAL

摘要

The present patent relates to a way of using a silo that makes it possible to separate sand from powdery material which, when in excess, is prejudicial to the use of sand in civil engineering. This allows using sand in conformity with the standards of the Brazilian National Standards Association (ABNT), and also using the separated powdery material for specific applications, such as pipe laying.
