Abstract
A tubular free-fall separator for the electrostatic separation of particles of a plastics mixture, includes two parallel opposite rows of vertical tubes which are either arranged rotatably around their own axis or are fixedly installed and are connected with a direct current voltage source for maintaining an electrostatic field between the rows. The tube rows are arranged in such a manner that two adjacent axis points of the tubes of one row always form a parallelogram, which has no right angles, with the opposite adjacent two axis points of the tubes of the other row.
