iDEAL® EvoLock® Yankee Dryer
Our new EvoLock® decision, starting from the fantastic technological base of our Yankee Dryer Forged® YD, accommodates all the A.Celli utilized sciences already acknowledged and appreciated, like utilizing a monobloc shell solid from a single metallic ingot. The novelty lies in a novel and very fashionable head-to-shell connection system, which does not require utilizing structural welds or bolts. This decision permits, from an engineering viewpoint, to scale back the deformation of the shell edges induced by the deformation of the heads, which in itself is attributable to the inside steam stress. This important attribute improves the runnability on sheet edges and consequently the effectivity of the machine.
The actual design moreover permits to reduce the final width of the shell, supplying you with the potential of drying a much bigger format sheet with the similar current machine gauge and, as we’re going to analyze inside the subsequent paragraphs, to reduce the obligatory inspection interventions.
Required inspections: comparability between EvoLock® and completely different metallic Yankee Dryers
For our analysis, we’re going to bear in mind two forms of metallic Yankee Dryer within the market:
- A typical Yankee Dryer with welded shell and shell associated to the heads through full penetration structural welds.
- The model new A.Celli iDEAL® EvoLock® decision, with solid shell and a model new head-to-shell connection system who does not require bolts nor welds.
The subsequent desk compares the forms of the required checks for the aforementioned Yankee Dryers by means of the primary 12 years of life.
