What are the materials of ceramic grinding balls?

Alumina grinding balls, zirconia grinding balls, zirquat beads, etc., mainly depends on which industry or use they are used for.

Alumina ceramic grinding balls are made of high-purity alumina powder by isostatic pressing and sintering at high temperature. The density of 92 alumina balls is about that, the Mo-type hardness is in grade 9, the water absorption rate is close to 0, and the self-abrasion is in %.

Glass grinding, first of all, the hardness of glass is very high, the ordinary grinding medium has limited processing capacity for him, and the mixing of too many impurities will greatly reduce the quality of the glass, resulting in the poor condition of the finished glass and the inability to make high-quality products. And alumina grinding balls can solve this problem very well.

Quartz grinding, the same quartz hardness is also very high, especially the high white quartz has high requirements for whiteness, and the color of alumina happens to be white, which solves the grinding problem of high white quartz from many aspects.

Depending on what material you grind, as well as the requirements for grinding materials, if you want to grind silicon carbide, many of them use pressureless sintering silicon carbide ceramic balls.

Strong cutting ability, obvious effect of removing scratches and oxide layer.

Porcelain ball filler, also known as inert alumina porcelain ball, porcelain ball filler is widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries, as a catalyst carrier material in the reactor covering and packaging, the main function of the packaging type porcelain ball is to increase the gas or liquid, the strength of the catalyst carrier and protection activities are not high. According to the content of inert alumina porcelain ball filler Al2O3, ceramic balls can be divided into: ordinary ceramic balls, inert alumina porcelain balls, medium alumina ceramic balls, high-alumina porcelain balls, 99 high-alumina porcelain balls, concave-convex groove open-pore porcelain balls, active porcelain balls, open-cell ceramic balls, microporous C ceramic balls regenerative ceramic balls.

Grinding porcelain ball grinding is fine grinding equipment, such as ball mill, vibrating grinding groove machine, and so on. Grinding porcelain balls have high hardness, bulk density, high corrosion resistance, wear resistance and grinding efficiency than ordinary stone or natural stone, and are widely used in ceramics, glass, enamel, pigments, chemical and other industries. According to the different content of Al2O3, the grinding porcelain ball is divided into silicon carbide grinding porcelain ball, porcelain ball, porcelain ball microcrystalline grinding and grinding aluminum and aluminum.

So what is the difference between these two types of alumina porcelain balls?

First of all, of course, the effect is different. The main function of this packaging porcelain ball is to increase the distribution point of gas or liquid, support and protect low-strength active catalysts, and the grinding porcelain ball is used for grinding of fine grinding equipment such as ball mills, pot mills, and vibrating mills.

Secondly, the size of the filler porcelain balls with different sizes of the two porcelain balls is smaller, generally with a diameter of 10mm-30mm, and the most commonly used is 25mm. and grinding porcelain balls are generally used more than 50mm.

In addition, the amount of alumina varies. The alumina content of ordinary filler porcelain balls is not high. Between 25% and 70% commonly used, grinding ceramic balls requires a high aluminum content due to various requirements such as hardness. It is usually used for 95% alumina content.

Filler porcelain ball, also known as inert porcelain ball, is used in petrochemical coal chemical industry, mainly because it does not have any reaction, and is completely the role of filler.

Grinding porcelain balls are used to grind various things, and it has the properties of inert porcelain balls, so grinding porcelain balls can sometimes be used as filler porcelain balls, but filler porcelain balls cannot be used in the grinding field.

Filler porcelain balls are divided into active fillers and inert fillers, the difference between active fillers and ground porcelain balls is large, and the difference between inert fillers and ground porcelain balls is very small.

It has the advantages of high density, high mechanical strength and good wear resistance. Grinding porcelain ball is an economical and widely used non-metallic grinding medium, grinding porcelain ball is mainly used in machinery, electronic banquet, aerospace and other fields, and can also be used in fertilizer, chemical and other industries.
