Vibrating Screen Sizing Formula by VSMA bulk . 17-6-2008· Vibrating Screen Sizing Formula by VSMA; If this is your first visit, be sure to check out the FAQ by clicking the link above. I am looking to size a vibrating screen and have found the VSMA formulas online, but I have not found any that reference where the formulas are found in print.
The formula works fine for all screens no matter what type, tonnage, decline or color. Because the tph value that you enter into the formula only represents the oversize passing over the end of the deck (after all the undersize has been removed), we are only calculating bed depth at that single point the discharge end of the screen.

VSMA Approved Method The Vibrating Screen Manufacturers Association (VSMA) is the industry standard screen area calculation method. First developed in the 1960's and adopted by VSMA in 1967 it is the recommended calculation methodology.
In the VSMA screen area calculation, Factor A represents the amount of feed that can be handled per square foot of deck area for various size screen apertures. This basic capacity is an empirical value that has been established assuming that the feed gradation to the deck comprises 25% of material larger than the apertures, and 40% of the feed ...

They can range from 4' to 12' wide and 6' to 32' long. The width of the screen determines the carrying capacity of the screen deck, while the length of the screen determines the overall efficiency of the screen. Typically, the length of the screen is 2.5 to 3 times the size of the width. Every manufacturer has its own screen sizing formula.
Current screen capacity calculations do not take into consideration enough of the factors affecting screen efficiency. The old formulas were designed to keep calculations short and manageable for manual calculation. The common use of computers in today's world makes it possible to do more
