Our client is an American multinational corporation in the plastic sector with offices and production plants in 23 countries and over 35,000 employees.
The client’s need to improve its performance in recycling material waste, whereby they currently only use one material granulator, led SatrindTech to suggest using two twin lines to handle plastic material in PPE. One line will be used to reduce the volume of sprues, while the other will be used to process waste from the plant’s extrusion line.
The engineering of the line consists of three elements: an automatic hoist tilter, a dual shaft shredder (model: K 8/25) and a transport belt placed after the shredder to transport the shredded material to the mill.
The process provides a total automation of the process for the cargo and discharge of material, whereby cargo is carried out by placing the material cargo into the hoist tilter which will lift and carry the material into the hopper. Once the material has been shredded in the shredding room, it will be transferred to the mill using the transport belt. The whole process cycle is managed by a PLC Siemens control panel.
While this solution is in itself a solution that has already been tried and tested during SatrindTech’s history, its uniqueness lies in the fact that the main electrical panel that governs the plant was designed and uses components in accordance with UL 508 / NPFA 79. Therefore, the electrical panel had to be completely redesigned, in keeping with IEC standards, for the use of components that respected the UL standards, as the on-board wiring had to reflect the similar requirements. All of the electrical cables had to be reviewed and replaced in keeping with European standard supplies.
In essence, this legislation regulates the provision of equipment and instructs the technical characteristics which the machine(s) must possess for the United States. Where the certification, in accordance with these regulations, is a contractual requirement, the SatrindTech and its Engineering are able to satisfy any such problematic requests.
