Abstract
A jigging machine comprises at least one pulsation chamber, particularly for finest grain sizing of coal or other minerals which traverse the jigging machine on the jig bed which is shorter in the direction of motion of the minerals that at right angles to the direction of motion, whereby the jigging machine is designed as a bottom-pulsed machine. The jigging machine comprises curved lateral walls whose curvature is such that only tensile stresses occur in the walls, is designed suspended in an upper frame, and has the pulsation chamber disposed immediately below the jig bed which rests on cross tie rods.
