Two mass vibrating screen . Brute Force Mechanical Vibratory Feeders The electro-motive drive is older than the magnetic drive for vibrating equipment especially for screens but vibratingThe two induction motors synchronise themselves automatically on the bases of mass.
General Kinematics STM-SCREEN™ Two-Mass Vibratory Screens utilize GK’s proven Two-Mass, natural frequency drive design. This design is load responsive and capable of longer material retention times to work the material more. This means you can get more screening accomplished in the same footprint as your old brute force screens.

The STM-SCREEN™ Two-Mass, extra large vibrating screens for bulk processing utilize GK’s proven Two-Mass, natural frequency drive design. This load-responsive design is capable of longer material retention times to work the material more.
Two-mass design achieves up to 5 times electrical savings over typical direct drive screens (150 HP+ compared to GK’s 30 HP). GK Two-Mass Screens are load responsive. The higher the tonnages, the higher the screening efficiencies. Two-mass design maintains stroke level, while brute force loses stroke as more material is added.

11-9-2012· re vibrating screen efficiency calculation. Hello Raj, Screen efficiency is obtained using different equations, depending on whether your product is the oversize or undersize fraction from the screen. The following information is required to calculate the two screen efficiencies;-Qms(f) = Mass flow rate of solid feed.
For linear vibrating screen and high frequency vibrating screen, the poor screening quality may be related to the movement direction of eccentric block, because two groups of eccentric blocks with the same mass need to rotate in self-synchronization and reverse direction to produce a single exciting force along the vibration direction at each
High frequency vibrating screens are the most important screening machines primarily utilised in the mineral processing industry. They are used to separate feeds containing solid and crushed ores down to approximately 200μm in size, and are applicable to both perfectly wetted and dried feed.
Contributor; The three masses are equal, and the two outer springs are identical. Figure XVII.6 shows the equilibrium position. Suppose that at some instant the first mass is displaced a distance \(x\) to the right and the second mass is displaced a distance \(y \) to the right.
Two-mass design achieves up to 5 times electrical savings over typical direct drive screens (150 HP+ compared to GK’s 30 HP) . GK Two-Mass Screens are load responsive. The higher the tonnages, the higher the screening efficiencies. Two-mass design maintains stroke level, while brute force loses stroke as more material is added.
Innovative structural solution for heavy loaded vibrating screens. Author links open Notwithstanding the higher stiffness and resistance of the body of the modified screen, its mass is only 2050 kg with an increment of 0.04% with respect to two on each stiffened side-wall of the screen at the unloading side (Fig. 13b), two on
The new machine is a free circular motion vibrating screen. The vibrator unit is composed of a shaft with two bearings and counterweights. This means the main radial load rotates with the shaft while the outer ring is stationary. The application drawing is shown in fig. 1.
We are a medium-sized, privately owned company and an international leader in the field of vibration technology. Our core competences are the design and manufacture of vibrating screens, vibrating drives as well as setting up
Abstract: Based on a company's production of single shaft circle vibrating screen, we set up the mechanical model of two degrees of freedom and the vibration differential equation to get the natural frequency of the system, and compared with the working frequency of vibrating screen, it can be roughly judged whether the system work normally

Vibratory Screens custom built screening solutions While a brute force/direct drive screen would require over 150 horsepower to operate, a two-mass screen that relies on background vibration
The vibration of this type screen is created by two eccentric shafts, rotating in opposite directions. This gives the box a linear motion. The stroke angle would depend on the relation of the eccentric weights of the two shafts to each other.
JÖST dual-mass resonance conveyors are used for transporting bulk material and general cargo over long conveying distances. An oscillating system consisting of a trough unit, counter-vibrating frame and working springs is excited at very low frequencies by an eccentric slider-crank drive.
4-3-2016· Figure 2 shows the model of vibrating screen considered in this study, where is the mass of the vibrating screen when in operation; is the moment of inertia of the center of mass of the vibrating screen with respect to -axis;,,,and are the stiffness of springs in horizontal and vertical directions in front and rear positions, respectively
