22 Jul 15: Applications 21: Control Systems

Those of us used to dealing with physical items, and I'll throw paper scientists, mechanical engineers and chemical engineers into this basket, often take controls, control schemes and control programs for granted. This is a mistake. Do a Pareto analysis of your major causes of downtime, and I'll suspect electrons of one use or another rank high on the list. And we are content with this.…See More

1 Jul 15: Materials 11: Printing your Paper Machine in situ

In the past, we have shared our vision of "printing" a new paper machine in place rather than fabricating it elsewhere and moving the pieces to the erection site and assembling them.  We see this first happening with machine frames, and perhaps first with dryer frames. Of course, by "printing" we mean Additive Manufacturing or 3-D Printing. For more, click here...See More

Today, we do not bother with cladding, stainless is cheap enough that nearly all wet components are stainless without cladding. Relative to everything else, materials are becoming less and less expensive.  We are also seeing more substitutions where traditionally items made of metals have been made of plastics.…See More

You may think we are always talking about new machine installations here at the Light Green Machine Institute. We are not. We are talking about your machine, your pulp mill, or whatever operations you are in charge of today.For more, click here.See More

Light Green Machine Institute Weekly 13 May 15: Applications 19: Controlling and Measuring Quality

It has always puzzled me--the location of the paper machine gauge. It is at the dry end, often after the calender stack. I once worked on a machine that had three gauges, but that is another story--most just have one. This has troubled me for a long time--the location of the gauge. For more, click here.See More

6 May 15: Applications 18: Segregation, part 2

It occurred to me since last week's column that there is another way to achieve the same idea (separating the atmosphere of the machine motors from the atmosphere of the machine) in a way that may be superior. That way is this...For more, click here!!!See More
