how to determine required screening area a separate calculation is required for each deck of a multiple deck screen, although the same formula is utilized for each calculation screening area = u = square feet: a x b x c x d x e x f x g x h x j: the succession of unknowns that must be established before using the formula is as follows:.
a vibrating mechanism attached to the middle of the screen imparts rapid vibrations of small amplitude to its surface, making the ore, which enters at the top, pass down it in an even mobile stream. the spring-loaded bolts, which can be seen in section in fig. 7, move with a hinge action, allowing unrestricted movement of the entire screening surface without transmitting the vibrations to the frame.
