Case: Mondi Stambolijski Bulgaria: Trim handling system for a winder.
The customer’s trim conveying system was not efficient enough. The existing system was ejector-based. The winder was not able to run at full speed and the ejector air was blown to the pulper causing the area to become overpressurised. Additionally, the energy consumption was too high.
Installation of a Trimvac® trim conveying system as well as design and supply of new trim chutes. The equipment installation was carried out during a short shutdown. The tight schedule included installation, commissioning and start-up of the systems, since it was an online winder. A successful delivery ensured that the production did not suffer.
The winder is able to run at full speed even with significantly wider trims. The energy consumption is reduced. The pulper area is no longer overpressurized, resulting in reduced humidity in the area thus eliminating the corrosion of the equipment.
After a successful start, the winder was immediately able to run smoothly at full speed, trouble-free. There were three main results: Full capacity of the winder could be utilized, energy savings and reduced corrosion.
