Stroke Setup
A few suggestions:
1. VSMA is a general guide for vibrating screen setups .....not of course thee bible
2. Would definitely check with SCHENcK for their mfr spec setup firstly
3. If you are screening desired TPH and efficiently, change nothing
4. If your chart is from SCHENCK use it...in my opinion
5. Stroke at 5mm long (nominal 3/16" +-) for horizontal is good depending on size of aperture your are screening at.......
6. We are basically lifting the material up in the air here, around 5mm high, allows coarse and fines to GO UP.....and hopefully allow fines to pass an opening in the screen media.....before being tossed up again.....
7. if SCREENING SUCCESSFULLY ...do NOTHING.....DON'T WORRY, BE HAPPY

Stroke For Hot Pellet Screen
Hi ,
We have a hot pellet screen made by Schenck . Now we decided to decrease size of screen dimensions because of operation conditions. Screen is a horizontal screen with two exciters and two mass and spring system (to reduce forces transferred to the steel structure). Also exciters are installed to the screen body with 30º .
Firstly I started to calculate stroke of the present screen. I find that stroke is 5 mm, vertical g is 2,5 g and total 5 g.
It is not recomended stroke value in the VSMA Book. But screening is successful.
My Questions;
I) Should I take 5 mm stroke for designing new screen or use mentioned strokes in the VSMA,
II) If I can use 5 mm stroke, can I use attached table for conveying velocity.
Thansks for helps
Best Regards,
