There are also vibrating screens that are loaded by the center and the product moves radially to the outputs that are on the periphery. For the correct advancement of the product it is necessary that the process is continuous, and it is due to the vibration if the screening surface is horizontal. Most of the screens have a certain inclination in such a way that the advance movement of the product is due to a combination between gravity and vibration.
4.1 Classification Based on Sieving Vibrating screens The basic method of operation of a screen is very simple. The screen presents a barrier to the passage of oversize material while it readily passes undersize material. It is only necessary to ensure that each particle has an opportunity to reach the screen.
VIBRATING SCREEN CAPACITY CALCULATIONS Throughput per square foot of screen area is the name of the screen game, and no design engineer wants to be considered short in the area of capacity and efficiency. It behooves the buyer/operator to examine and evaluate the data available before committing to any screen type or system.

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 .
The Horizontal Vibrating Screen: 840 rpm , 1/2 stroke at 45°. Each has a .063 dia. wire screen with 1/8 clear opening, moving under a particle travelling at an assumed 20 fpm, for A, 40 fpm for B., 80 fpm for C, and 60 fpm for D. Omitting details
Title: VSMA screen calc method
V belt drives for free floating screens, positive drive screens and horizontal screens will be discussed next, INCLINED FREE FLOATING VIBRATING SCREENS The drive on 2 bearing screens without pivoted motor bases should be placed on the horizontal centerline of the driven sheave, either atthe feed or discharge end of the screen, so load variations on the screen will not tighten or loosen the V belt When no pivoted motor base is used, the manufacturer should have the driven sheave designed ...
