Embodiment 1

[0038] Example 1 A ball-making process in the process of producing inorganic fibers from red mud

[0039] Specific steps are as follows:

[0040](1) Add the red mud with a water content of 14% or less to the red mud silo of the four-bin batching machine, and at the same time add the curing agent cement, the acidity coefficient regulator particle size less than 180 mesh silica powder, and the solvent-assisted limestone crushed stone respectively Add the corresponding auxiliary material silo of the four-bin batching machine;

[0041] (2) The red mud, curing agent, acidity coefficient regulator and co-solvent in the silo are sent to the crushing mixer through the conveyor at a mass ratio of 1:0.13:0.13:0.04, and the feed of the crushing mixer Humidification devices are installed at both the mouth and the discharge port. When the red mud, curing agent, acidity coefficient regulator and co-solvent enter the crushing mixer, the humidity is 8.5%, and the humidity of the material at ...

Abstract

The invention designs a ball producing process and a ball producing system in the process of producing inorganic fibers by using red mud. The process comprises the following steps: firstly, adding materials into a stock bin; secondly, feeding the red mud, a curing agent, an acidity coefficient modifier and a cosolvent respectively into a crushing mixer according to a mass ratio; thirdly, feeding the crushed and mixed materials into a ball press machine, wherein the tangential pressure of a ball pressing part in the ball press machine is more than or equal to 2 tons / cm<2>; fourthly, sending ball-shaped materials into a ball bin tank body for curing and drying in shade. The ball producing system comprises a dosing machine, the crushing mixer, the ball press machine and the ball bin tank body, and the devices are connected with one another by a conveyor. The ball producing process disclosed by the invention has the advantages of low cost and high dosing precision, and the process flow is simple and convenient for programmed operation; in addition, the obtained ball-shaped materials have the advantages of low frangibility and uniform size, thereby facilitating transportation; when the inorganic fibers are produced, all that is needed is to proportionally mix the red mud with coke, the operation is convenient, and the produced inorganic fibers and inorganic fiber products are stable in quality.

Description

technical field [0001] The invention relates to a ball making process and a ball making system in the process of using red mud to produce inorganic fibers, and belongs to the technical field of comprehensive utilization of red mud. Background technique [0002] Red mud is the residue produced after alumina is extracted from bauxite through the "Bayer method" or "sintering method". The amount of red mud produced is related to the production method and ore grade. Generally, 1-1.7 Tons of slag, these slags are reddish-brown because they are rich in iron oxide, are called red mud, which is a hazardous solid waste. The lower the grade of raw materials, the greater the amount of red mud produced. The physical test results of red mud show that the melting point of red mud is 1200-1250°C, the pH of the exudate of red mud is 10-12, the particle size is 0.08-0.25 microns, the relative density is 2.7-2.9, and the apparent relative density is 0.8- 1.9; The chemical composition varies s...
