PROCEDIMIENTO Y DISPOSITIVO PARA LA OBTENCION DE POLVO DE PLOMO PARCIALMENTE OXIDADO

摘要

In a process and a device for manufacturing partially oxidized lead dust from lead pieces, the natural pile of dissociated coarse and fine material formed in a rotating drum is mechanically disturbed by radially extending guide plates in the interior of a drum which plates are arranged in pairs and displaced toward each other by 180 DEG in the direction of the circumference of the drum and the individual plates of each pair of plates are spaced axially apart, by which arrangement the efficiency of the process and the product quality are greatly improved.
