The screen will be small so it would be relatively easy to get the screen that has a big operating window and controll the flow with a frequency controller. ■
Re: Best Design Point For Feed Variation.
Thanks Ziggy
I am confident we can make the right selection.
However, I am hesitant to install a VVVF.
For a fixed speed drive, is it better to design screen for the median operating point? ■

In this instance you shall design the screen for the maximum load - midpoint is fine for low and mdedium load but what is going to happen when have high load and your screen is not up to it? ■
Design For Worst Scenario
When we speak to folks about sizing an application...we typically ask what is average TPH......and what is MAX tph....we design for the bigger or worst case.....to fills all needs. ■
Re: Best Design Point For Feed Variation.
Then what are the other criteria to be considered for sieve design (or selection)? ■
Other Criteria?
Sorry, I did not understand what you are asking. ■
Re: Best Design Point For Feed Variation.
I mean; what should i consider during the design process of the screen except capacity? Hardness of material? Size range? And what? ■

Your question is very general - you're asking for someone to explain to you the whole design process. There are diffrent types of screens and different applications and different design philosophies.

Best Design
Dear Sir,
Please design the as stated below.
1.Provide a surge hopper over the screen.
2. Locate a vibrating feeder below the surge hopper with VVVF drive.
3. Design the screen for 100 tPH.
This will solve the prioblem.

Best design point for feed variation.
Greetings All.
I am trying to reccommend a screen mod to a colleage who is thinking about replacing an existing screen in his plant.
The problem is the feedrate to this screen is very varibale, with a range of 50tph-100tph.
Assuming that this variability cannot be resolved.. can anyone suggest what is the best point to design to?
I have considered reccomending designing to a middle point i.e. 75tph, to minimizing overloading/underloading during normal operation, but there is also a case to be made for designing for maximum tonnages.
Any advice here?? ■
