摘要： A method and apparatus are disclosed for continuously drying, preferably with agglomeration and/or coating and sizing, and separating a solid product from a liquid feed material, especially bauxite slurry which passes through a very sticky phase during drying, without significant encrustation of the equipment used. The method comprises: spraying a liquid bearing solid material upwardly into a drying zone, feeding a drying gas into the drying zone from below the spraying liquid in substantially parallel flow, removing the mixture of the drying gas and entrained dried particles from the drying zone, separating the entrained dried particles from their mixture with the drying gas, returning the separated dried particles to the drying zone, and collecting the dried particles, characterized by arranging for the formation of a slower moving boundary layer within the feeding of the drying gas, through which boundary layer dried particles are allowed to fall under gravity to be collected, and by collecting the dried particles continuously from below the spraying liquid.

摘要： A description is given of a method as well as a plant for dewatering a filter cake in a vacuum filter (1 ) subject to simultaneous supply of steam-laden gases, where the filter cake is subsequently calcined in a calciner system (2) through heat exchange with hot exhaust gases. The method and plant are peculiar in that the steam-laden gases comprise hot exhaust gases from the subsequent calciner system. It is hereby obtained that the filter cake can be dewatered at significantly lower costs to essentially the same residual moisture as attainable for known devices. This is due to the fact that the need for specialized processing equipment for producing steam is eliminated by utilization of hot exhaust gases from the calciner system.
摘要翻译：给出了一种方法以及用于将真空过滤器（1）中的滤饼脱水的设备，同时供应含蒸汽的气体，其中滤饼随后在煅烧系统（2）中通过加热煅烧与热排气交换。该方法和设备是特殊的，因为含蒸汽的气体包括来自后续煅烧系统的热废气。因此，可以以显着降低的成本将滤饼脱水，基本上与已知装置可获得的残余水分基本相同。这是因为通过利用来自煅烧炉系统的热废气来消除用于生产蒸汽的专用加工设备的需要。
