Medium alumina ceramic ball and preparation method thereof

Abstract

The invention relates to the technical field of medium alumina ceramic ball formula, and particularly relates to a medium alumina ceramic ball and preparation method thereof. A medium alumina ceramic ball, is mainly prepared from 400-500 parts of low quality processed aluminum ore powder lot, 20-30 parts of kaolin, 20-30 parts of barite, 20-30 parts of dolomite, 10-20 parts of sodium potassium feldspar, 200-300 parts of return material, 300-400 parts of brick, 40-60 parts of calcium sulfate, 30-40 parts of mineral fiber, 10-15 parts of charcoal fiber and 40-60 parts of black earth, after the raw materials are mixed, a mixture is obtained, and the materials are processed. The medium alumina ceramic ball possesses an economical and rational formula of the raw materials, the ceramic balls prepared according to the formula has excellent mechanical force properties and chemical stabilities, and is worthy of being actively promoted.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of formula of medium-aluminum ceramic balls, in particular to a medium-aluminum ceramic ball and a manufacturing method thereof. [0003] 【Background technique】 [0004] As we all know, there are many types of aluminum-containing ceramic balls, including ordinary aluminum-containing ceramic balls, medium-aluminum ceramic balls, high-alumina ceramic balls, activated alumina ceramic balls, and inert alumina ceramic balls. It is non-toxic, odorless and has the functions of purification, adsorption, catalytic protection and drying. It can be used in chemical, petrochemical, fertilizer, pharmaceutical, smelting, building materials, gas and environmental protection industries. It has a wide range of uses. As the aluminum content of ceramic balls increases, medium-alumina ceramic balls, activated alumina ceramics and high-alumina ceramic balls have the characteristics of higher strength, better wear resista...

AI Technical Summary

Problems solved by technology

At present, due to the high content of Al2O3 in medium-alumina ceramic balls and high-alumina ceramic balls, most manufacturers use smelted aluminum ore with an Al2O3 content of 75-80% as the main raw material to produce medium-alumina ceramic balls and high-alumina ceramic balls. The demand for medium-alumina ceramic balls and high-alumina ceramic balls is increasing day by day, and the raw materials used to make medium-alumina ceramic balls and high-alumina ceramic balls—cooked bauxite, especially high-quality smelted bauxite is becoming more and more scarce, causing cooked The supply of aluminum ore is in short supply, and the price is also rising all the way, which not only limits the production demand of high-alumina ceramic balls, but also greatly affects the production demand of medium-alumina ceramic balls

In the absence of adding medium-quality smelted ore and high-quality smelted smelt ore, when only low-quality smelted smelted ore is used as the main raw material and matched with existing auxiliary materials, the manufacturing process of medium-alumina ceramic balls cannot achieve high-alumina ceramic balls. Compared with the performance of medium-aluminum ceramic balls and particularly high-quality medium-alumina ceramics, the performance is also quite different. It is difficult to form the ball during the pressing process, and it is difficult to control the temperature during firing, which causes difficulties in production and large fluctuations in product quality. , not only increases the production cost of the enterprise, but also affects the use effect of the product
