ABSTRACT:
A method for separating tobacco and sand in stemmery discards is disclosed. The sand tobacco mixture is passed through dryer (14), to reduce the moisture content, agitated by conveyor (16), passed through sieve (18), to obtain the correct particle size and to mechanically agitate the mixture, and is then passed through electrostatic separators (24) and (25) to separate the sand from the tobacco. Portions of the electrostatically separated sand tobacco mixture may be passed through another electrostatic separator (26) to achieve a further separation of sand and tobacco.
