Abstract

The present invention discloses a fly ash raw material pellet production apparatus, which comprises a material bin, conveyors, a pellet pressing device and a sieve, wherein the outlet of the conveyor 1 is connected with the raw material bin, the outlet of the raw material bin is connected with the conveyor 2, the conveyor 2 is connected with the pellet pressing device, the material outlet of the pellet pressing device is connected with the conveyor 3, the conveyor 3 is connected with the material inlet of the sieve, the oversize material outlet of the sieve is connected with the conveyor 4, the conveyor 4 is connected with a sintering kiln system, the undersize material outlet of the sieve is connected with the conveyor 5, the conveyor 5 is connected with a lifter, the lifter is connected with a broken pellet bin, and the outlet of the broken pellet bin is connected with the conveyor 2. According to the present invention, the raw material obtained by mixing the fly ash and the ammonium sulfate can be prepared into the raw material pellet, and the raw material pellet does not contain water and any other adhesives so as to effectively achieve energy saving and consumption reduction; and the physical performances of the raw material pellet can completely meet production requirements of the sintering kiln.

Description

technical field [0001] The invention relates to a device for preparing fly ash raw meal pellets, in particular to a preparation of raw meal pellets mixed with fly ash and ammonium sulfate applied in the "process of preparing alumina by fly ash-ammonium sulfate sintering method" device. Background technique [0002] There are many methods of producing alumina by using fly ash, among which the "fly ash-ammonium sulfate sintering method" is used to produce alumina by sintering fly ash and ammonium sulfate in a rotary kiln. [0003] In this production method, some process schemes mix fly ash and ammonium sulfate with dry powder to configure dry powdery raw materials into the rotary kiln for sintering. However, during the sintering process, the dry powder raw material melts and sticks to the wall of the rotary kiln, which affects heat transfer and is difficult to clean. [0004] Some process schemes adopt wet pelletizing process, that is, add water to fly ash and ammonium sulfa...
