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 packing material for baking and particularly relates to a processing method and a processing system for the packing material for baking applicable to producing anodes, cathodes and electrodes for aluminum. The processing method for the packing material for baking comprises the following steps: sending metallurgical coke to sieving equipment for sieving; sending the metallurgical coke with qualified sieve size into a finished product screw conveyer; sending the metallurgical coke with unqualified sieve size to the processing equipment for processing; and sending the metallurgical coke which is sent to the metallurgical coke to a finished product silo. The invention adopts processing technology of the packing material for baking to process the metallurgical coke through crushing and sieving into a finished packing material product with optimum matching which has a size fraction of between 0.5 and 6 millimeters and has compressibility, adsorptivity and gas permeability, improves the volume density and the mechanical strength of a baked product and reduces the contraction rate of a green body. The method improves production operation environment. The method effectively solves technical problems that raw materials of the packing material have small selectivity and high cost, and the packing material can cause serious environmental pollution and raw material loss during the 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...
