UniSort Flake – sorting of bulk materials

UniSort Flake – excellent fine product sorting by type or colour

Our UniSort Flake is a sorting unit for separating bulk materials in the fraction range of 3 to 25 mm. It consists of a feed and dispensing device with a material hopper, an acceleration conveyor belt, a containment hood and a compressed air nozzle bar.

The sorting unit is available as "UniSort Flake P" with a high resolution NIR (near infrared) camera or as "UniSort Flake C" with a highly selective colour detection unit.

Sorting can be performed depending on application, e.g. in the case of PET flakes by type or colour. Incorrect colours and unwanted plastics are precisely removed from the PET flow. This ensures very high purity of the sorted material.

The material is passed through a feed and dispensing device and lands on the integrated conveyor belt. The feed material is accelerated by a high-speed belt and pressed onto the belt using the active object control (AOC) system developed by us at STEINERT – and is held in a stable position even after leaving the belt. This relatively elaborate but effective stabilisation helps to steady even the smallest objects on the belt in a controlled manner and keep them in the calculated position on the parabolic trajectory after leaving the belt.

Whilst the sortable material flows through the detection area, the corresponding sensor detects the type or colour as necessary and the position on the conveyor belt. The controller then activates the correct nozzles at precisely the right time and position. The nozzle bar is arranged above the material flow and shoots from top to bottom. Detected foreign particles are then extracted exactly and with low material loss by a targeted blast of compressed air. The sorted fractions can be transported to the next processing stage on material discharge conveyors.

The UniSort Flake is also ideal for use in metal recovery when it comes to cleaning strands of copper or aluminium. Extremely high levels of purity are achieved in sorting copper/aluminium.
