/. A vibrating screen, also known as a separator or sifter, is a machine that is used to separate particles or materials into different sizes based on their particle size or shape. Here is a guide covering the definition, types, working principle, price considerations, and applications of vibrating screens.
Calculating Screen Efficiency. Step #1 – Calculate oversize in feed. 860 TPH Feed x 73% passing 1 1⁄4"= 630TPH undersize in feed. Step #2 – Calculate TPH undersize in deck oversize. 382 TPH Oversize x 40% passing 1 1⁄4" = 152 TPH undersize in overs. Step #3 – Calculate TPH undersize that passes the deck. 630 TPH – 152 TPH = 477 ...

This is found to be 500 ft/hr. Next, measure the bulk density of the material being sorted. In this case, the bulk density is measured to be .0225 tons/ft^3. Finally, calculate the Vibrating Screen Capacity using the formula and information above: VSC = D*W*V*C. VSC = .5*3*500*.0225. VSC = 16.875 tons/hr.

Vibrating screen. This example shows the bearing selection process applied to an application case in which a vibrating screen manufacturer is selecting the bearings for a new machine. Each step of the example is described in an expandable/drop-down section below. The steps in the example follow the sequence in the bearing selection process.
percentage of small feed material the greater the screen capacity. The faster the material passes through a screen the more open area there is left to screen the remaining material. A feed material with 40% of the feed being half the opening size or smaller equates to a factor of 1.0 . Figure 6 uses the percent of feed material half the
