Vibrating Screen Efficiency Calculations - MEKA For the efficient use of screens, number of conditions need to be met, starting from the selection of a suitable screen. Many factors related to the screened material, such as type, humidity and size distribution should be considered in the selection of the right screen.

Dear All, How to calculate the rate of travel or velocity of material on feeder if we know the stroke angle, motion type (linear/ circular), speed of feeder in RPM? As per VSMA for horizontal screen it is 45 fpm and for inclined screen 75 fpm, but what is the formula for exact velocity of material? Regards, StuD

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 each deck opening. • Unique factors of that application. •

I'm trying to carry out some calculations such as G-Forces, Beddepth and Velocity of material on the deck, for our Vibrating screens. Could you please help me with formulas to calculate this parameters. I have all the other parameters …

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.

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.

Screen Stroke The shape and amplitude of the motion of a screen. Usually screen strokes are circular, oval or straight line strokes. • Open Area The area available on a screen for a aggregate particle to fall through a hole in a screen. Usually expressed as a percentage. • Screen Efficiency

Amplitude = 4 to 5 mm. Speed = 1000 rpm. Weight of feeder including vibrator = 3000 kg (approx) max. feed size of material = 600 mm. amplitude = static moment /wt of structure including vibrator. so static moment = 4 mm x 3000 kg =1200 kg.cm. I am going to use two vibrator for getting linear motion.

B. The Shaking Screen: 475 rpm, 1" stroke, zero pitch, 6 deg. slope. C. The Inclined Vibrating Screen: 1200 rpm, 1/4" vertical circle dia. D. 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
