Engineering technology for a rock wool insulation production facility

Project description

Knauf Insulation, a leading international manufacturer of insulation materials, offers a one-stop-shop for complete solutions from the basement to the roof for new builds and modernisation. We provided the EI&C planning and installation, as well as the automation and control technology and switchgear construction for a new production facility.
The new production line extends over a length of approximately 200 m. The electrical supply is provided by two new transformer stations, a low-voltage main distribution board and four electrical distribution compartments. With a construction time of just 10 months, this was a very ambitious investment project.

The production line is divided into the following subsystems:
stone silo, binder storage, binder preparation and dosing, furnace system, de-fibering system, blow-off units and binding agent injection, primary scale and shuttle and belt conveyor systems including a secondary scale, pre-press and longitudinal pressing station, annealing oven, cooling zone, longitudinal saw and edge chippers, crosscut saw, gauge saw, dual thickness grinder, ejector for manual stacking, collection shaft extraction and filter chamber, hardening furnace extraction and filter unit, cooling zone extraction filter unit, water treatment and cooling systems.
