Different to other type screens the vibromotors of high-frequency screens are mounted on each deck instead of on the screen body. Aggressive vibration is applied within a range of 3600–5000 RPM directly to the screen media
These vibrating screens can be constructed in either single or a double deck design and used as a heavy duty primary or scalping screen. Inclines of these hi-scalp vibrating screens range from 15-30 degrees and use either singular or double shafted centrifugal circular motion mechanism.
A double-deck linear motion vibrating screen is simulated using the DEM software LIGGGTHS. DEM is used to obtain the ore parameters in the steady state and the force on the screen decks.
The vibrating screen is efficient and it saves plenty of time and it can do work that would normally take several people to do. The vibrating screen is very much helpful since it makes the process of manufacturing a lot easier and ten times more efficient than doing it manually.
6 Vibrating screen is a vibrating system. Thus screen deck mass plus material mass on deck is total mass which is resting on springs. This is vibrated by exciting force. Mass spring stiffness damping factor hysteresis losses and exciting force are complementary; and together will create desired vibration.
Screening is an important operation in mineral dressing for the preparation of the feed material to the next process. Types and Sizes: We make Single Double and Triple deck Vibrating screen with size of the deck from 600 mm 900 mm 1200 mm and 1500 mm width while the length varies from 1200 mm to 3000 mm. Capacity: Capacity of the screening
The experimental data were collected from two large-scale double-deck vibrating screens of identical characteristics. They operate with a small angle of inclination and with fixed vibration.

The fed particles will fall and hit the vibrating deck then either pass the deck and report to the underflow or flow along the screen to exceed the discharge end and report to the overflow as shown in Fig. 3. Their movement details
Vibration screen efficiency affected by different factors such as screen deck inclination mesh size of screen Amplitude of vibration feed rate of material etc. In this study we considered effect of deck slope inclination on screening efficiency of vibration screen.
Abstract - In this paper we simulated the Screen deck inclination and its effect on screening efficiency of a linear vibrating screen using the Discrete Element Method DEM . The simulation carried out on Bulk flow Analysis Software.
