Washing

The washing system consists of a rotating barrel that serves to separate different materials according to their specific weight. The physical principle of the selection process involves turbulent motion, which can be adjusted according to the incoming water flow. While lighter materials are kept on the surface (floating) by the turbulence, and dragged in the direction of flow, the heavier materials are collected together on the bottom. As the barrel rotates during processing, it conveys the heavy materials in the opposite direction to the water flow.

The washing water is conveyed for recycling, first passing into the holding tank to remove the coarser materials. A pump collects the cleaner water from the upper layer and emits it back into circulation. The process sludge will tend to build up on the bottom of the sedimentation tank, where it will be filtered and disposed of according to current standards.

At the end of the process, the selected and washed materials will include, for example: mixed metals, steel and rubber, lithoids, and inertoids, which, according to their characteristics, can be sold on as Secondary Raw Materials, sent for waste to authorised external plants for recycling/disposal, or sent to other plant sections (e.g., for manual sorting into the different metals).
