摘要： A method and apparatus for heat treatment of lime mud comprises drying of the lime mud to be introduced into the lime reburning kiln (5) in a pneumatic dryer (3) by means of flue gases discharged from the lime reburning kiln in order to regenerate the lime content of the lime mud. From a drying filter (6), the lime mud thickened to a dry solids content of over 75 %, preferably to 80 %, is introduced into a feed chamber (2) through which an adjustable portion of the flue gas is conducted. Depending on the gas amount, 100 % or less of the lime mud is entrained with the gas into the dryer (3), the remaining portion falling into the lower section (14) of the feed chamber, wherefrom it is further transferred into the lime reburning kiln (5).

摘要： A rotary kiln (10) is employed which is inclined downwardly from its charge end (12) to its discharge end (14) and has a maximum length to breadth ratio of 5:1. The interior space of the kiln (10) is heated by means of at least one burner (B1, B2) directed into the kiln from one end thereof to a substantially constant elevated process temperature. Material is fed into the kiln (10) so that it occupies a maximum of 10% of the cross-sectional area of the internal space of the kiln (10) at the charge end (12). Upon entering the kiln the material is subjected almost immediately to the required process temperature. As it moves along the bottom of the kiln (10) from the charge to the discharge end (14), heat transfer to the material is primarily by radiation from the combustion space and from the lining of the kiln (10).

摘要： In the method, a hot gas is flowed linearly through a slightly inclined treating area. Colemanite ore particles are repeatedly elevated and dropped substantially vertically through the gas while they are simultaneously advanced countercurrent to the gas flow. This movement is continued until the ore particles are heated to the point of decrepitation at which they relatively suddenly break into a large number of relatively fine particles of substantially sure colemanite which are carried out of the treating area by the gas stream. The gas carried colemanite particles are then separated from the gas stream to provide an upgraded and classified product. Gas velocity and temperature and the path and rate of movement of the ore through the gas are varied as required to obtain a given grade or size in the recovered colemanite product. The apparatus used in practicing the method includes, in a preferred form, a tubular calcining drum which is inclined slightly with respect to the horizontal. Lifters are positioned along the internal wall of the calcining drum and the drum is rotated between two stationary end assemblies. Ore particles are introduced into the upper end of the drum and a stream of hot gas is introduced through the lower end of the drum. Rotation of the drum causes the ore to be repeatedly lifted and dropped across the gas stream while the ore simultaneously advances from the upper toward the lower end of the drum. The temperature of the advancing ore increases to the point required to cause decrepitation of the ore, and the gas stream flowing through the drum carries the particles of decrepitation to the upper end of the drum where they are removed and separated from the gas stream. In the preferred form, gas leaving the drum is conveyed to a second rotating, inclined drum which functions as a preheater for ore being introduced into the calcining drum.

摘要： This invention relates to a method of and apparatus for pyroprocessing raw material having a reaction temperature and containing moisture into sinter. The apparatus has a rotary kiln adapted to receive the raw material pellets at one end of the rotary kiln and to move the raw material pellets along a path of movement in the rotary kiln to the other end of the rotary kiln. Heating means are adjacent the other end of the rotary kiln for directing a heated fluid through the rotary kiln, the rotary kiln having a drying means adjacent the one end of the rotary kiln for heating the raw material pellets by the heated fluid to substantially remove the moisture in the raw material pellets. Cooling means communicate with the drying means for mixing a cooling fluid with the heated fluid to limit the temperature in the drying means below the temperature at which the raw material pellets explode due to rapid heating to a deleteriously high temperature. The rotary kiln has a preheating zone adjacent the drying means further along the path of movement for heating the raw material pellets to a temperature below the reaction temperature. The rotary kiln has a reaction zone adjacent the other end of the rotary kiln for heating the raw material pellets above the reaction temperature to pyroprocess the raw material pellets into the sinter. Restriction means are between the preheating zone and the reaction zone for damming a reservoir of the raw material pellets adjacent the restriction means so that the reservoir of the raw material pellets is protected from the direct radiation of the heated fluid and the temperature of the reservoir of raw material pellets remains unaffected by instantaneous changes in the temperature of the heated fluid, the restriction means being operable to meter minimum layers of the raw material pellets into the reaction zone so that the minimum layers of the raw material pellets are individually and rapidly heated to the reaction temperature by the heated fluid and the raw material pellets are converted into sinter. The method includes the steps of receiving the raw material pellets at one end of a rotary kiln and moving the raw material pellets along a path of movement in the rotary kiln to the other end of the rotary kiln; directing a heated fluid through the rotary kiln; heating the raw material pellets by the heated fluid adjacent the one end of the rotary kiln to substantially remove the moisture in the raw material pellets; mixing a cooling fluid with the heated fluid to limit the temperature (during the removal of the moisture) below the temperature at which the raw material pellets explode due to rapid heating to a deleteriously high temperature; heating the raw material pellets in a preheating zone of the rotary kiln further along the path of movement to a temperature below the reaction temperature; damming a reservoir of the raw material pellets adjacent the preheating zone and further along the path of movement so that the reservoir of the raw material pellets is protected from the direct radiation of the heated fluid and the temperature of the reservoir of the raw material pellets remains unaffected by instantaneous changes in the temperature of the heated fluid; metering minimum layers of the raw material pellets adjacent the preheating zone and further along the path of movement into a reaction zone of the rotary kiln adjacent the other end of the kiln; and heating raw material pellets individually and rapidly in the reaction zone of the rotary kiln to indivIdually and rapidly heat the raw material pellets to the reaction temperature by the heated fluid, thus converting the raw material pellets into the sinter.
