Complex Screening

The application of traditional screening methods is used as a pre-treatment process to remove plastics, steel, paper, cloth and wood.   The plant would typically consist of a primary screener removing oversize hard material feeding to an aggressive three way screener or trammel discharging to separate streams for air jetting to remove light fractions, coarse aggregate washing to remove organic debris and finally to hand picking stations

By the clever modification of the vibrating screener decks, Heijmans and HBR have successfully converted the process into a complex asbestos cement fragment removal system.
