Vibrating scalping screens are traditionally used to remove impurities or oversize in a bulk material process. Also known as trash screens they can help protect the plant from unwanted contamination.
Common applications for scalping screens includes:
- Removing material that has clumped together in the manufacturing process.
- As insurance against impurities that may fall into the material during processing or storage.
- Preventing oversize particles from blocking equipment such as transfer chutes or crushers.
As a large percentage of the material will pass through, the screen size area does not need to be as large compared to a sizing screen.
To pass the volume of product through, scalping screens are typically designed with an open trough discharge.
Retro fitting scalping screens to existing plants is a common practice as unforeseen contaminants affect plant operations significantly. Compact units, installed at transition points and other areas where space is limited can be designed by Vibroflow.
