A system for separating glass particles from a mixture containing magnetic materials and glass, which system comprises a completely enclosed apparatus which protects against pollution by harmful silica dust and avoids excessive abrasion of conveying mechanism by utilization of pneumatic impulse feed devices whereby mixed particles are transported from a pressure vessel to one of a series of magnetic roller separators and further including dust separation or air cleaner means whereby substantially only glass and magnetic particles to be separated are introduced into the magnetic separators.
