The recycling facility’s waste stream consists of single stream material which contains high volumes of recyclable material. The Impact density separator, with zigzag baffles, provides extremely high levels of separation resulting in a gratifying stream of clean glass that will go on to remelt and reuse. Other materials captured from the <2” waste stream are light plastics, trash and fibre. Ferrous removal can be added post zigzag with a simple magnetic head pulley on the outbound material conveyor.
The infeed to the ZAC800 enters through a heavy duty rotary valve with moulded single piece rubber blades for extended wear and flexibility which will allow for proper metering of the material to the zigzag separator and contain the vacuum in the separation chamber.
The zigzag chute includes internal baffle plates to ensure the falling glass material is interrupted as it cascades through the hood, causing the lighter material to be separated and lifted from the heavier glass.
The zigzag baffles are constructed from chrome carbide cast alloy wear plates to exceed 500BHN hardness to ensure improved durability, thus reducing downtime. With the use of moulded rubber rotary valve veins, cast Chromium wear plates and stainless-steel splash plates, the ferrous material can be removed post zigzag after the light fraction is removed from the stream as there is no issue with magnetic materials commonly found in the <2” material in a single stream facility building up and blocking the zigzag chamber and rotary valve. This allows for a far cleaner removal of the ferrous material.
Impact used its largest zigzag unit at the Anaheim site, which has a constant 8” gap between the internal baffle plates allowing increased glass throughput, but also allow large oversize objects to pass, reducing the potential to block the system. The cleaned glass exits the last zigzag section and deposits directly to the existing glass transfer conveyor exiting the building.
