A fastening arrangement between a riding ring and a casing of a rotary cylinder, whereby the riding ring encircles the casing of the rotary cylinder with clearance, including support elements affixed to the casing of the rotary cylinder and projecting radially outwardly. The riding ring has at least one circular groove on a surface thereof. A plurality of clamping elements are distributed around a perimeter of the riding ring, the distributed clamping elements engaging in a force-fit manner with the circular groove of the riding ring. The clamping elements are connected with the support elements, whereby the riding ring is immobilized in both the axial and circumferential directions relative to the casing of the rotary cylinder. The support elements affixed to the rotary cylinder casing have spring guides oriented axially relative to the rotary cylinder, between each of which is positioned a clamping element tensioned in a force-fit manner on the riding ring.

Fastening of a riding ring to the casing of a rotary cylinder

A rotary drum for tumbling a granular product therein for heat transfer or drying with arcuate baffles mounted on the inner surface of the drum with the concave surface of the baffles facing outwardly and the baffles having rims at the ends to restrict discharge of material from the baffles and the baffles being offset circumferentially in a trailing downstream direction with openings through the baffles and an angled downstream edge of certain baffles with other baffles having a portion of the downstream edge removed and the baffles formed in two sections hinged to each other with the ends secured to the inner surface of the drum.

Baffles for tube coolers, rotary tubular kilns or the like

A rotary kiln construction of the type where a cylindrical kiln is supported for rotation on an annular bearing ring wherein the ring has an inner circumference larger than the outer circumference of the kiln cylinder and a plurality of spacing plates are arranged around the circumference of the cylinder to support the bearing ring concentrically with the cylinder, supporting assemblies for the spacing plates including a support element welded on the cylinder with abutment strips preventing axial displacement of the bearing ring and angle lugs preventing axial displacement of the spacing plates with the support assemblies located axially opposite each other so as to hold the plates between them and permit withdrawal of the plates from either axial direction.

Arrangement for mounting a bearing ring on a rotary cylinder

A rotary kiln construction wherein the kiln cylinder has an annular bearing ring for supporting the kiln in rotation with spacer plates located between the ring and the outer surface of the cylinder and circumferentially spaced from each other with supporting assemblies at each axial side of the bearing ring secured to the outer surface of the cylinder having retaining elements projecting on both circumferential sides of the plates and being radially outward of the plates to provide a radial inward support to the plate ends constructed for retaining the plates and for ease of replacement and removal without rewelding the full plate assembly on the cylinder.
