A simple definition of a “screen” is a crusher with a surface (s) used to classify materials by size.
Screening is defined as “The mechanical process which accomplishes a division of particles on the basis of size and their acceptance or rejection by a screening surface.”
Knowledge of screening comes mainly from experience. However, through experiment, test facilities and compilation of field data, reliable criteria has been developed by screen manufacturers. This factual data is now tabulated for use in selecting the type and size of screen best suited for the job.
The most common application of a vibrating screen is to separate an unconfined conglomerate of materials into different size fractions. Other popular uses of screens are scalping, washing, dewatering and de-dusting. A review of the duty is essential to know the type of screen to recommend. When this is established, the capacity chart is then used to determine the size unit required.
Nordberg Screen
Nordberg supplies different types of screens each designed for a specific range of duty. Occasionally there is a choice between the types we offer. In these cases when there is doubt, you can rely on Nordberg experience to help you make the selection.
We begin with a very brief description of the Nordberg screens line . Refer to the literature for further details.
