The material velocity of a circular vibrating screen can be calculated from the corrected theoretical speed of the product formula written below. Example: Determine the material velocity of a screen vibrated at 900 RPM with a 12 mm stroke and 20° degree inclination angle. To calculate

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 complex screen capacity calculations in much shorter time.

Basic capacity figure is expressed as . tph per sq.ft. • Figure is multiplied by the sq. footage of the screen deck. • Calculation gives the basic capacity of each deck and the total capacity of the vibrating screen. • The vibrating screen capacity is determined: • Using a standard sizing formula (9 variables). • Basic capacity of

Average ores carrying up to 10% moisture can be screened to 10 mesh without previous drying: beyond that, the vibratory screening should be wet with 3 to 3.5 ratio of water to ore. Approximate Tons thru screen per square foot screening area per 24 hours, wet or dry. moisture and screen efficiency Screen Capacity of Crushing Plants Screens are made of perforated steel plates or woven wires

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 Applies when open area of screening surface is less than the open area shown in the Factor "A" capacity chart. Factor "G" =

Unbalance motors are provided and are suitable for driving vibrating systems, such as vibrating pipes, vibrating feeders, vibrating screens,

screen sheaves are specially machined so that, when in operation, there is a point of zero sheave run out. In other words, if a line were drawn from the center of the driven sheave through the center of the motor sheave, there would be no movement towards or away from the motor sheave where that line crosses the outer diameter of the screen
