For low maintenance, high production.

The CBI Prescreener is a low-maintenance, high-production means of separating dirt and abrasive fines out of all types of fed material. It is a reliable machine due to its rugged, simplistic design.

The open-top design allows the operator to feed in large volumes of brush, stumps, C & D, yard waste, grass, bark, bulky, or irregular material without binding or clogging.

Used in front of a CBI Grizzly Mill, the CBI Prescreener reduces the amount of component wear on the grinder and increase productivity. Whether used as a stand-alone unit or feeding a grinder, this prescreener will reliably deliver the tonnage needed to keep a high production grinder working at full capacity.

Designed to work in tandem with the CBI 4800 Magnum Force or Grindall to remove abrasive fines prior to grinding, as well as, provide a picking station for contaminants that cannot be mechanically removed.

The Prescreener separates feed material into three fractions:

• fines
• ferrous metals
• overs ready for processing

The CBI Prescreener is available in a stationary or portable model, with either diesel or electric drive.
