structural strenght of slotted screen
(OP)
Hello,
we are looking at building a new batch pulp digester to replace our venerable almost 100 Y old ones. The original sulfite digesters are made of 'black steel' lined with brick. We will replace one of them with 2205 SS. The new digester will a bit different and we will try it for few years before we will replace all of the others.
The digester has liquor recirculation and the collector ring in the current model has vertical slot. The slot pattern in the current digester works fine but with the new digester we will need a different plate arrangement with the similar pattern. I am a little but concern with the structural strength of the new model of screen plate to avoid the screen plate collapsing.
Any one has any advise on how to estimate the strength of a slotted screen
thanks
Eric

You may not buy from one of the ones you ask first, but you have to ask first before you can start talking about quotes.

"digester" ... lots of vibration ? ... hard to analyze

Different perforators have pretty good knowledge of their products. You may want to discuss what you want whttp://www.eng-tips.com/viewthread.cfm?qid=378645i... a perforator before getting too deep into the design so that you can avoid the cost of new tooling.
