The tribo-electrostatic belt separator is relatively compact. A machine designed to process 40 tonnes per hour is approximately 9.1 meters (30 ft.) long, 1.7 meters (5.5 ft.) wide and 3.2 meters (10.5 ft.) high. The required balance of plant consists of systems to convey dry material to and from the separator.

A triboelectrostatic separation system consists of a tribo-charging of materials and a separation of the charged materials in an electric field. Selective charging and optimum charge density (charge-to-mass ratio: nC/g) of materials in tribo-charging are the most important parameters for separation efficiency. In this study, a new tribo-charger ...
