Vibrating screen

Roc vibrating screens are installed on site with an angle of 15-20°. They feature a basic design and are especially useful and cost-effective for screening rocks and other materials. The vibrating unit consists of an unbalanced eccentric shaft with counterweights allowing for different stroke travels to generate a circular motion.

General SCREEN Information

The tension spring is always located towards the screen sheave. The location of the motor on the pivot base is very important as well. By locating the center of the motor one to four inches horizontally past the center of the motor base, away from the screen sheave, the weight of the motor actually assists in maintaining belt tension. Final belt

Vibrating Feeders: How They Work and Effectiveness

Eccentric Weight This is the weight attached to the shaft or flywheel with a slight offset from the axis of rotation. Rotating the shaft produces an unbalanced moment creating oscillations. ... A way to counter the high vibration transmitted is to use a counterweight or counter-vibrating double troughs. ... If this vibrating screen medias ...

VIBRATING SCREEN

Apollo make Vibrating Screen consists of two spherical roller bearings in each housing with bore sizes up to 140mm. These housings are connected using a cardan shaft which reduces the weight of the vibrator mechanism, reduces shaft deflection and increases the space between the decks when changing screen media.

How To Size and Select a Vibrating Screen for an

What is a Vibrating Screen? Vibrating Screens are machines used to separate aggregates by particle size by means of an exciting force applied to the machine. The vibration lifts the material, causing it to stratify, allowing the smaller material to move from the top of the depth of material to the bottom of the material, thus exposing them to ...

Exciter Mechanisms & Vibration Types

Exciters are the main vibration source of the screens. They generally comprise a housing, bearing, shaft and an eccentric mass. The vibration results from the rotation of the eccentric mass about the exciter shaft. Generally, power is transmitted from the drive motor to the assembly via a V-belt transmission. ... The stroke length can be ...

Evaluation of the movement performance of a vibrating screen …

Essentially, most vibrating screens operate with a shaft that has two eccentric masses attached, one on each side.
