Thevibratingmachine with thedual-masssystem driven bytwoexciters is avibrating screen. Tables 1 and2show the parameters ofvibrating screenand parameters oftwoexciters of thevibrating screenseparator as shown in Figure 9, respectively.

Vibrating screen“dual mass”Designed for high capacityscreeningand required low power. The performance and low maintenance costs ofDual mass vibrating screensare ideal for the most demanding screening applications. They are available in fixed configurations of centrifugal force (FRC) and use adual masssystem.

General KinematicsTwo-Mass Vibrating Screensall include the following features:Two-massdesign achieves up to 5 times electrical savings over typical direct drivescreens(150 HP+ compared to GK's 30 HP). Load responsive, the higher the tonnages, the higher thescreeningefficiencies.Two-massdesign maintains stroke level,...

Sep 11, 2012· revibrating screenefficiency calculation. Hello Raj,Screenefficiency is obtained using different equations, depending on whether your product is the oversize or undersize fraction from thescreen. The following information is required to calculate thetwo screenefficiencies;-Qms(f) =Massflow rate of solid feed.

The rotary electric vibrators are designed with two sets of weights mounted on each end of the motor’s shaft (see the cutaway photo below for the basic design). These weights become the “unbalanced” mass that is used to generate vibratory force as the vibrator rotates.

Jan 01, 2017· This paper will present some actual examples of the use ofTwo-Mass screensas a solution to these overloading problems and the advantages ofTwo-Mass screensin other high tonnage applications.Brute Force Drive Compared toTwo MassDriveVibratingScreensThe standard singlemass screenas depicted by figure 1 is generally recognized in the ...

To break through the drawbacks of the one-mass vibrating screenlike pluggingscreen, high noise and etc., a new vibrationscreenwithtwo-massand high energy which could generate transient high vibration intensity was analyzed. To meet the requirements of energy-saving and system stability, a spring with nonlinear and hard features was used in the main vibration system.

Dual mass vibrating screensare available in various widths, depths and lengths. he steel screener can be customized based on your application (one or more screening decks, openings of thescreen, crown deck, etc.). The centrifugal force transmitted by the counterweight motors can be adjusted with counterweight.

For linearvibrating screenand high frequencyvibrating screen, the poor screening quality may be related to the movement direction of eccentric block, becausetwogroups of eccentric blocks with the samemassneed to rotate in self-synchronization and reverse direction to produce a single exciting force along the vibration direction at each ...

Freelyvibrating screens. By freelyvibrating screensone meansscreensthat are supported on springs, and the box is vibrated by avibratingmechanism (also called an exciter) which vibrates thescreenbox in various ways, depending on the type ofvibratingunit. Circular motion.Screenswith a circular motion are the most common type.

Oct 16, 2015·Screening of Materials and Types of Screens. ... The tuned spring-mass, or natural-frequency,vibratingconveyor is sometimes adapted, in balanced or unbalanced versions, to screening applications. In a few exceptions, the vibration is applied directly to thescreenmedia mounted in a stationary frame. ... Thetwomost common types ofvibrating...

However, we’ve found that converting it into this slightly more user-friendly configuration does the trick, F =2.85E-5 x unbalanced x rpm2. The unbalanced is the weight of the rotatingmassx the distance from the center of gravity of thatmassto the center of rotation, units being inch-pounds.

The energy in a sound wave is both kinetic and potential. Just as in avibratingspring, the medium hasmassand moves and so movingmassis kinetic energy.
