The Purpose of a Vibrating Screen. Bulk material processing plants make use of vibrating screens powered and supported by vibrating feeders and electric vibrators to separate and process particles. This process of screening material is applied in order to size, scalp, classify, dewater, deslurry, and remove dust from the desired material.Web

VSC = D * W * V * C. Where VSC is the vibrating screen capacity in tons per hour, D is the depth of the bed, W is the width of the screen, V is the speed of travel of the material on the screen, and C is the bulk density of the material. The depth of the bed refers to the thickness of the material on the screen surface. Generally, a screen's ...Web

Speed and Stroke are selected based on the application. Vibrating screens typically operate with a vibration G-force between 3G to 7G (3 to 7 times the force due to gravitational acceleration). Following are the typical G-force levels as per one of the leading vibrating screen manufacturer. Inclined Screen: 3.3 to 4.0; Horizontal Screen: 4.5 to 7.0Web

In coal preparation, screening machines serve two purposes: sizing and media recovery. Oftentimes, the initial screening is performed by a scalping screen located outside the plant. This prevents the screens inside the plant from becoming overloaded. The deslime screens make the next cut and most prep plants size to minus 1 mm.Web

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 the screening surface.Web
