### SCREEN CAPACITY CALCULATION - VIBFEM

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.Vibrating Screen Capacity Calculations – MEKA 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 the bed depth of the material, the following formula is used.Dynamic design theory and appli ion of large vibrating screen Conventional static strength calculation and analogy method was used in the design of vibrating screen in our country at present which neglect the dynamic characteristic influence of higher modal frequencies on the vibrating screen. High exciting force is likely to lead to fatigue damage of vibrating screen.

### DESIGN AND ANALYSIS OF SHAFT AND BEARING FOR VIBRATING SCREEN

The design is based on the standard design procedure. In the present work by using the standard design procedure diameter of vibrating screen shaft has been designed. Select the bearing based on shaft diameter from the standard design data and calculate the bearing life.Vibrating Screen Design Parameters Screen amperage and overload calculations are based on the greater of either the total screen feed or the oversize tonnage. Total feed load is based on the assumption that a screen area of 14.9 m 8 ft x 20 ft is capable of handling 1000 tph. Oversize load is based on this same screen handling 700 tph of oversize.Construction, Working and Maintenance of Electric Vibrators . 6 Factors Affecting Screen Performance 42 7 Vibrating Screen Installation, Start up and Adjustments 54 8 Operation and Maintenance of Vibrating Screens 57 9 Checking of Stroke Length and Stroke Angle 63 10 Natural Frequency and Resonance 65 11 Optional Design Features 67 - References 70
