Embodiment

[0030] 1) Grinding dolomite, barium carbonate, bauxite, porcelain stone and calcined fossils to particles with a particle size of 0-3mm, and screening the raw materials to 40 mesh;

[0031] 2) Weigh the corresponding raw materials according to the mass components of 5% dolomite, 5% barium carbonate, 80% bauxite, 5% porcelain stone, and 5% calcined fossil, and perform the first wet grinding to 400 mesh after mixing evenly , and then carry out the first slurry sinking, and the slurry sinking time is 24 hours;

[0032] 3) The raw materials that have been slurried once in step 2) are wet-milled to 800 mesh for the second time, and then slurried for the second time, and the slurring time is 24 hours; to remove iron;

[0033] 4) Add the binder and stir, mix the binder and the raw materials obtained in step 3) according to the ratio of 1:9, and then stir evenly;

[0034] 5) The raw materials in step 4) are granulated through a spray drying tower to obtain raw materials of 60-100 me...

Abstract

The invention provides a formulation and technology of medium-high-alumina ceramic balls. The medium-high-alumina ceramic balls comprise the following raw materials in percentage by mass: dolomite, barium carbonate, bauxite, chinastone and calcined fossil; the technology comprises the steps of wet grinding for twice, precipitating for twice, adding a binding agent for uniformly mixing and firing, so as to obtain the medium-high-alumina ceramic balls. With the adoption of the medium-high-alumina ceramic balls prepared by using the formulation and technology provided by the invention, the defects that the conventional medium-alumina ceramic balls and medium-high-alumina ceramic balls are relatively low in bulk density, higher in abrasion loss, lower in hardness, and not pure enough in color and luster, and the using function loss of the medium-high-alumina ceramic balls reaches or is close to the using function standard of high-alumina ceramic balls.

Description

technical field [0001] The invention relates to grinding balls in the fields of industrial ceramic processing and the like, in particular to a formula and process for medium-high alumina ceramic balls that can effectively reduce wear and energy consumption. Background technique [0002] There are two types of grinding products commonly used in the market today, one is medium aluminum grinding balls and the other is high aluminum grinding balls. Medium aluminum grinding balls wear a lot during use, and it takes about 60 tons of medium aluminum balls to produce 10,000 tons of ceramic products; high aluminum balls wear less, and they need to consume about 12 tons per 10,000 tons of ceramic products. The price discourages many users, and the scope of use is small. [0003] Medium-high alumina ceramic balls overcome the disadvantages of high wear and high energy consumption of medium-aluminum balls, and their performance indicators are close to those of high-alumina balls, but t...
