Steel and Aluminum Dryers
As we have stated previously, we are going to be taking the ideas developed in this column over the last couple of years and developing them into design practices.  This is how it works.  We will provide the basic narrative here for one design practice each week.  We will keep it open for comments for one month.  After that, we will finish it in formal form and offer it for sale at a modest price.  Here is where you come in.  If you make a substantive contribution to a standard, the organization for which you work will be granted a pro bono license to use that standard with its current issue number for as long as you like.  We have had good response so far!  Contribute, please

This week's:
Steel and Aluminum Dryers (LGM 2013.011.01
when issued)


Cast iron dryer cans are the classic case of something that exists because we have always done it that way.At the time that they were invented, they were the only economical material available.More than 150 years have gone by and we are still using them.

Alternative material such as Steel and Aluminum offer much more attractive options: The materials are lightweight (meaning they will require less starting torque and smaller gear trains), have better heat transfer coefficients and are safer, not to mention they will also reduce foundation and structural loads.


To eliminate the use of cast iron dryer cans, replacing with alternate material such as steel or aluminum.

So, give us your comments by 16 April 13, please!

Hi Jim,


In my former paper research life, I developed a laboratory papermachine to form paper modeled on commercial scale machines ... this technology was transferred to CSIRO in the form of a modified MK systems former...anyway, whilst I haven't engaged with the paper literature for sometime I'm sure this lab papermachine could be used to meaningfully study this effect of 'squaring the sheet' [probably by shaking the whole machine with some rock music!]...anyway.... as a result of research changes at CSIRO this machine is sitting idle [somewhere]...as we don't do significant pulp/paper research as a team...and as a matter of personal pride for me I'm wondering if there's a home somewhere in the US who might like to take it on ...??
