### SCREEN CAPACITY CALCULATION

modified version of the VSMA (Vibrating Screen Manufactures Association) formula to determine screen capacity. The twelve factors used in the formula below are based in large part on the VSMA charts and formula. Formula: A = B * S * D * V * H * T * K * Y * P * O * W * F “A”, the calculated capacity per square foot of screen area in tons per hour. B = Basic capacity per square foot in tons

01/09/2009 Dynamic optimal design of vibrating screen The initial force mainly distributes on the side plate and cross beams when the vibrating screen works. Then it makes a rigid motion and elastic deformation which generates a greater dynamic stress on the side plate and leads to fatigue crack of the side plate [11] . Adding stiffeners to base structure [12] is an effective method to control stress

THE SCREEN WITH VIBRATING SIEVES In practice, a sieve design is limited to the determination of surfaces of the sieves. In most cases the sieve width and efficiency are imposed and then a designer is to calculate such sieve length that guarantees the desired efficiency. For this purpose a model with discharge function can be used (Sztaba 1993). The external surface of the granular layer
