Clean Rolls Make a Difference in Metal Processing Lines

Processing strip metal in continuous form is full of challenges. The strip is conveyed over and through numerous rolls, many of which contact the strip and have a direct effect on quality. Adding roll cleaning systems has proven to help maximum run rate, yield and improve product quality in these processing lines.

Dryer Bars and Paper Dryer Performance

Dryer bars are axial bars placed on the inside of steam-heated paper dryers to create turbulence in the rimming condensate layer. If the spacing of the bars is chosen correctly, resonant waves are created in the condensate film, between each pair of bars.

Advances in Press Roll Dewatering

Blind drilled, grooved, and suction drilled rolls are commonly used on presses in the papermaking process. The open areas in these rolls are designed to accept water from the fabric. It is important all the water in these rolls be evacuated before the nip to prevent re-wetting the sheet and to ensure optimum press nip performance. In some cases these rolls rely solely on centrifugal force to evacuate water, but this is often not sufficient, especially when the fabric becomes filled and cannot accept as much water.

Dryer Syphons

It has been well-documented that the distance between the condensate entrance of a syphon and the dryer shell, referred to as the syphon clearance, has considerable influence on the operational efficiency of a paper dryer. Suboptimal clearance adversely affects heat transfer capacity and the cross-machine temperature uniformity of the cylinder.

White Water Recovery – the Benefits Go Beyond Just Saving Water

Corporate sustainability statements often emphasize water reduction as a goal associated with minimizing a company’s environmental footprint and impact on the community. Being a “good neighbor” by optimizing the use of water and reducing water costs are the two most obvious benefits.

Revolutionary Change in Corrugating Steam Systems

Increased visibility into the system, from boiler to condensate return, maximum heat transfer, and improved runnability are what top-performing corrugators are saying can make a critical difference in their plants - allowing them to run consistently at cut-off knife speeds.
