摘要： According to the method, granular ore or ore concentrate is introduced into a kiln (1) for roasting the ore at temperatures of 400 to 1050 DEG C, whereby the ore in the kiln forms a stationary fluidised bed (3). The ore is projected onto the fluidised bed through an opening (16) in the kiln housing located above said fluidised bed, the ore being accelerated by the blades (14a) of a rotating projection wheel. Said projection wheel (14) lies outside the kiln in the vicinity of the housing opening. Preferably, the speed of the projection wheel is variable and the projection wheel can be displaced and/or pivoted in relation to the kiln.

摘要： A method for the heat treatment of solids containing iron oxide, in which fine-grained solids are heated to a temperature of about 630°C in a fluidized-bed reactor (1). To improve the utilization of energy, it is proposed to introduce a first gas or gas mixture from below through a supply tube (3) into a mixing chamber (7) of the reactor (1), the gas supply tube (3) being at least partly surrounded by a stationary annular fluidized bed (10) which is fluidized by supplying fluidizing gas. The gas velocities of the first gas or gas mixture and of the fluidizing gas for the annular fluidized bet (10) are adjusted such that the Particle-Froude-Numbers in the gas supply tube (3) are between 1 and 100, in the annular fluidized bed (10) between 0.02 and 2, and in the mixing chamber (7) between 0.3 and 30.

摘要： This invention relates to a process for producing e.g. anhydrous metal oxide from metal hydroxide, wherein the metal hydroxide is at least partly dehydrated and preheated, before the metal hydroxide is introduced into a fluidized-bed reactor (19), in which the metal hydroxide is heated to a temperature of about 650 to about 1250°C by combustion of fuel, and metal oxide is generated, wherein primary air and/or secondary air enriched with oxygen is supplied to the fluidized-bed reactor (19). To achieve a rather low dust emission and a small amount of grain disintegration, the oxygen or the gas enriched with oxygen is introduced into the fluidized-bed reactor (19) with a low gas velocity.

摘要： This invention relates to a process for producing metal oxide from metal hydroxide, in which the preheated metal hydroxide is at least partly supplied via at least one pneumatic delivery conduit and via at least one downstream separating cyclone (8, 11) to a fluidized-bed reactor (12), where it is heated to a temperature of 650 to 1250°C by combustion of fuel, and metal oxide is produced. In a mixing vessel (19), the metal oxide is mixed with a partial stream of preheated metal hydroxide such that the preheated metal hydroxide is further heated and at least partly calcined. Then, the metal oxide is supplied from the mixing vessel (19) to at least one cooling stage (27, 28, 30, 31). The energy utilization of the process is increased in that the waste gas of the at least one separating cyclone (8, 11) is introduced into the mixing vessel (19) as conveying air such that the metal oxide from the mixing vessel (19) is pneumatically delivered into the at least one cooling stage or a de livery conduit (24) leading to the same. Furthermore, the invention relates to a corresponding plant.
