Optional reverse pulse dust collector available on request to avoid the use of dust socks.
Debagging: The system is designed with Twin Station Debagging allowing for continuous processing from 1 bag at a time. A Sensor mounted above the discharging Rotary Valve will alert the control system to divert to the other bag once it is empty and illuminating a light bar on the front of the bagging station for operators to identify a bag needs to be changed.
The material is then pneumatically conveyed to a Pre Cleaner for separation of dust and labels.
The dust and labels are collected in a bulk bag or hopper(not included) and the PET flakes fall to the Flake Classifier (Linear Screener) mounted below. The purpose of the Flake Classifier is to separate flakes larger than 14mm and smaller than 3mm from the material. Testing shows that the majority of the contamination are particles smaller than 3mm. This also Flakes larger than 14mm may be granulated and returned to the process.
The classified flakes are then pneumatically conveyed to an Intermediate Dosing Hopper above the Flake Purifier fitted with High, Medium and Low Level sensors. The hopper is divided the same as the Flake Purifier allowing to dose the resort lane.
The SESOTEC Flake Purifier (Can be sourced direct or through Telford Smith) is installed on an included Mezzanine.
The sorted target material is pneumatically transported from the Flake Purifier to a Double Bagging Station.
Rejected flake is diverted back to the ‘resort loop’ of the SESOTEC Flake Purifier where reject material is blown to a reject Single Bagging Station and target material is returned to the Sesotec Flake Purifiers main line. The Target Fraction bagging station is fitted with Pneumatic Bag Shakers to provide maximum weights and balanced bag filling.
This system can optionally be provided with Bag Weighing and an automatic bag diverter. Alternatively target material can be blown to a customer supplied material Silo.
