What is the zta ceramic balls ?
Zta ceramic balls are also called Zirconia toughened alumina balls ,they are high-performance grinding media made of alumina powder and zirconium oxide powder in proportion.
They have excellent wear resistance, corrosion resistance and high temperature resistance in high temperature and strong corrosive environments. At the same time, zirconium-aluminum composite balls have high hardness, high compressive strength, good oxidation resistance, good wear resistance and impact resistance.
Because of zta ceramic balls' feature , it can be widely used in non-ferrous metal mines, industrial ceramics, non-metallic minerals, titanium dioxide, papermaking, coatings, inks and other fields.
Why does our company develop zirconium-aluminum composite balls?
Our company has developed different types of zirconium-aluminum composite balls with zirconium content of 5-75% and specific gravity of 3.2-5, mainly to meet the needs of customers for different grinding media densities under different working conditions.
What is the production process of zirconium-aluminum composite balls?
The preparation process of zirconium-aluminum composite balls includes mixing specific calcined alumina powder, certain zirconium-containing powder and other raw materials according to a ratio, grinding to a certain fineness in a ball mill, spray granulation, and then rolling into shape, and finally calcining at high temperature.
This perfect preparation process makes the surface of the ball smooth, the self-lubricating performance of the ceramic is outstanding, and the scientific sorting process ensures better roundness and low wear in grinding conditions.
At the same time, it also ensures that the zirconium-aluminum composite ball has good mechanical strength and excellent wear resistance, so that it can play an important role in grinding operations in copper mines and other fields.

How to choose the size?
Depending on the type of raw material to be ground, the fineness of the feed and discharge.
In addition, the available sizes (diameter, length) of the ball mill and the type of ball mill are also important.
What effect do you want to achieve?
1. Maintain uniform grinding particle size and improve product quality?
2. Improve grinding efficiency and increase output?
3. Maintain raw material purity and reduce material pollution?
4. Reduce the number of ball changes, reduce maintenance costs, and extend the service life?
5. Reduce costs.
What is the specific application of zirconium-aluminum composite balls?
1. Metallic minerals such as copper, silver, nickel, gold, zinc, platinum group metals, lead, etc.
For many minerals, medium density media (3.7-4.2 g/cm3) is the best choice, providing the right combination of stress strength and impact probability.
2. Non-metallic minerals such as graphite, calcium carbonate, kaolin, zirconium silicate, titanium dioxide, gypsum and quartz, etc.
Mineral pigments and fillers (such as TiO 2, CaCO 3, talc, clay, barite or zeolite) need to be processed in large mills for a long time.
The main challenge is to minimize the energy required to achieve the target grinding degree. Determining the right media is essential to optimize grinding and maintain operating efficiency. Bead density and size are the main selection criteria; choosing the right combination has a major impact on overall process economics
3. Advanced ceramic materials, frits and glazes.
4. Chemical materials, paints, pigments, inks, dyes.
Paint, ink and coating formulations typically contain pigments, fillers, additives and solvents, all of which are added to the binder. Solvents can be organic or water-based.
Producing a consistent and uniform product from such a diverse combination of raw materials is a challenge for the grinding process. The development of gloss and color intensity are both critical factors and are often highly dependent on the choice of media.
Application of zirconium-aluminum composite balls in copper mines?
Zirconium-aluminum composite grinding balls are composed of zirconium oxide and aluminum oxide. They have excellent properties such as high hardness, high density and high wear resistance. Therefore, their application in the mining industry is gradually increasing. Our copper mine guests especially like medium-density zta balls.
In copper mines, zirconium-aluminum composite grinding balls can be used in ball mills, autogenous mills, SAG mills and other equipment in copper mine grinding operations, which can effectively improve the efficiency of mineral processing production and reduce grinding costs.
Specific applications include the following aspects:
1. Improve grinding efficiency. Due to the high hardness and low wear of zirconium-aluminum composite grinding balls, the grinding efficiency of ball mills, autogenous mills and SAG mills can be improved.
