摘要： A rotary kiln having a polygonal lining is disclosed for pyro-processing cement, lime, other minerals, as well as other materials. Specifically, utilizing a polygonal lining of brick or a refractory or ceramic material having between 3 and 12 sides improves the heat efficiency or heat transfer between high-temperature gases and a burden of material to be processed by the kiln. Such an efficient utilization of the gas heat is due to various factors which cause a larger amount of the burden to be more quickly exposed to the high temperature gases. These various factors include increased tumbling, increased residence time, decreased degree of filling, and increased surface exposure.

摘要： A bloated granular clay product is manufactured by heating clay in a first step from atmospheric temperature to 300*-600* C. during a long period of time whereafter the clay now forming granules in a second step is heated to 1,150*-1,175* C. in a relatively short period of time i.e., about 15 - 30 minutes. The heating is effected in a rotary kiln having a drying section and a burning section. The first heating step is provided in the drying section and the second heating step takes place in a transition zone between the two sections. To ensure the quick heating in said second step there is provided heat transfer means in the transition zone.

摘要： A method and system for thermal processing of a material conveyed in a rotary kiln with a rotatable kiln drum, the drum wall of which delimits a heatable drum chamber, from a drum inlet to a drum outlet of the kiln drum. The drum chamber is heated directly by conducting a heating gas into the drum chamber. The drum chamber is also heated indirectly by warming the drum wall at least in areas.

摘要： A continuous rotary retort furnace includes an outer shell having first and second ends. A retort assembly extends through openings in the first and second ends. The retort assembly is supported by support devices at both ends external of the shell. The retort assembly is formed of an axial member and a spirally-wound conduit disposed on the exterior surface of the axial member. A drive assembly is coupled to the support device adjacent the first end for rotating of the retort assembly.

摘要： A rotary retort furnace wherein the retort is supported for rotation at only one end outside of the heated furnace shell such that the retort is cantilevered into the shell. The rotary retort has a charging door mechanism that cooperates with a skip hoist loading mechanism to provide charges of the parts to be heat treated that are of a uniform size and are introduced into the retort so as to minimize the loss of any controlled atmosphere. The skip hoist loading mechanism has a vibrating feed hopper that dispenses a weight controlled charge into a skip hoist bucket which, after receiving the predetermined charge of parts, is held in a ready position until such time as a cam mechanism controlling the opening and closing of a door on the charge end of the retort causes the door to open and the skip bucket to be moved to a position wherein the parts are dumped into the retort for heat treating. The internal auger flight for the retort is made by forming a number of toroids from a resilient material, radially cutting each of the toroids and deforming them to form individual flights, and connecting one of the split edges resulting from the cutting to the opposite edge of an adjacent flight such that an axially compressed helical subassembly is obtained. The helical subassembly is then screwed onto a shaft having a number of guide pins axially on the shaft at predetermined spacings thereby both axially extending and radially compressing the helical subassembly. The shaft and the helical subassembly are inserted into a retort shell and one free end of the subassembly is welded to one end of the retort. The shaft is then unscrewed from the subassembly while at the same time being forced axially into the retort such that the edges of the helical subassembly fit tightly against the inside of the retort. After the shaft has been removed, the remaining end of the helical subassembly is welded to the end of the retort.

摘要： A rotary furnace apparatus, especially useful for carrying out a reaction of fluorspar and sulfuric acid, is provided with a mechanical recycling means within the furnace itself. The recycling means is fixed to an inner shell portion of the furnace so that it rotates with rotational movements applied to the furnace shell by a single driving means. In one embodiment, the recycling means is in the form of a screw conveying device having a cylindrical tube mounted coaxially within the furnace shell, and with two spiral paths defined within the cylindrical tube for receiving and conveying residue material from a downstream area within the furnace shell to an upstream area near the inlet end of the furnace. The screw conveyor is provided with a pair of scoops to pick up residue material and to deposit the material in controlled quantities into the two spiral paths defined in the conveyor. In another embodiment, the recycling means is in the form of an open-ended helical passageway which follows the inner cylindrical wall of the furnace shell from an area of residue pick up to the inlet end of the furnace.
