IN-MILL ENERGY EXCHANGING DEVICE Russian patent published in 1995 - IPC

FIELD: grinding. SUBSTANCE: in-mill energy exchanging device is installed in drum 1 of the mill with lining 2. Ellipsoidal segment 5 is installed in lower part of mill body and inclined in the direction of mill discharging part. Inclined partition 3 is made of bent rods 7, convex part of which is directed to mill charging part. Deflection arcs of the bent rods are 0.2 - 0.5 of their diameters. Alternating monorails in pairs are installed along larger axis of the ellipsoid between rods. Upper parts of the monorails are directed to charging part. The rods are welded together by use of embedded parts. Lower parts of monorails are welded together by use of plates. Distance between monorails equals five-fold diameter of weighted average ball, and height of projected upper parts of the monorails should be more than diameter of weighted average ball of milling bodies. EFFECT: mill increased productivity and operating reliability. 2 cl, 4 dwg
