Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the examples, but the protection scope of the present invention is not limited by the examples.

[0028] The invention relates to a method for processing roasting filler, which comprises the following process steps: sending the metallurgical coke to a screening device for screening, and the metallurgical coke screened by the screening device is first screened by a grid sieve hopper and then sent to the screening device , the metallurgical coke screened by the grid sieve hopper is sent to the bucket elevator by the feeding equipment and then sent to the screening equipment. The processing equipment is used for processing. The screening equipment used is equipped with double-layer screens. The metallurgical coke in the bottom layer is sent to the powder screw conveyor; the metallurgical coke in the middle layer is sent to the finished product screw conveyor. The metallurgical coke is sent ...

Abstract

The invention discloses a calcined filler, in particular to a calcined filler processing method and system suitable for producing aluminum anodes, cathodes and electrodes. A method for processing roasting filling materials, comprising the following steps: sending metallurgical coke to a screening device for screening, sending metallurgical coke with a qualified particle size to a finished product screw conveyor, and sending metallurgical coke with an unqualified particle size to be processed The equipment will process the metallurgical coke sent to the finished product screw conveyor and then sent to the finished product trough. The present invention adopts the above-mentioned roasting filling material processing technology, and crushes and sieves the metallurgical coke into the finished product of the optimally matched filling material with compressibility, adsorption and gas permeability at a particle size of 0.5-6mm, which improves the roasted product. Excellent bulk density and mechanical strength, reduce the shrinkage speed of the green body. Improved production operating environment. The invention effectively solves the technical problems of low selectivity of filler raw materials, high cost, and serious environmental pollution and raw material loss caused by the filler during transportation.

Description

technical field [0001] The invention relates to a filling material processing method and system, in particular to a roasting filling material processing method and system suitable for producing aluminum anodes, cathodes and electrodes. Background technique [0002] The filler is the bulk granular material used to cover the green body and fill the gap during firing to prevent the green body from oxidation and deformation. The main functions of fillers during green body roasting are: 1. Prevent the green body from being oxidized in direct contact with the heating flame; 2. Fix the shape of the green body; 3. Conduct heat to the green body; 4. Retain the volatile content of the green body during roasting discharge channel. The roasting filler has a significant effect on the carbon residue rate of the green body during the roasting process, thereby affecting the physical and chemical properties of the roasted product, so the filler plays an important role in the roasting proces...
