De-powdering plant for a scrap shredding machine and relative method

A de-powdering plant able to be used downstream of a shredding machine and comprising a first processing section for processing a primary stream of powder and air arriving from a first exit line from the shredding machine, which comprises a unit for damping powders using humidity connected to an air intake downstream of the shredding machine, said first processing section also comprising a processing unit using active carbons filtration, downstream of the unit for damping powders using humidity, suitable for the adsorption of the volatile organic substances present in a stream of air exiting from the unit for damping powders using humidity, said plant comprises heating means to heat, directly or indirectly, the stream of air saturated with humidity exiting from the unit for damping powders using humidity, before it enters into the processing unit using active carbons filtration, wherein the processing unit comprises a feed line for air, heated by said heating means, which is fluidically connected to an exit line of the stream of air from the unit for damping powders using humidity, upstream of the processing unit using active carbons filtration, wherein the air from the feed line is mixed with the air from the exit line in order to generate a stream of air with reduced humidity entering the processing unit using active carbons filtration.
