Pressing
This is a common molding method for large-size ceramic grinding media. The main methods are dry pressing (with 3%-7% water or additives in the powder) and isostatic pressing (with less than 3% water or additives in the powder). In industry, a combination of both methods can be adopted.
After evenly mixing the powder and various additives, it is granulated by spray. Next, the granulated powder is added to a metal mold to transform it into balls. After that, the demolded blanks are subjected to cold isostatic pressing to obtain ball blanks. The blanks prepared by this process have high density, and the fired ceramic balls have high density and good quality. It is usually used to produce large, high-quality grinding balls with a diameter greater than 10mm.
Rolling
This method has the advantages of simple production equipment, raw materials, and operation, good sphericity, and easy sintering. The preparation cost is lower, and balls of various sizes within the range of 0.1mm-60mm can be produced as required.
The method of rolling clay segments into balls. The process is as follows: The powder, water, adhesive, plasticizer, lubricant, etc. are mixed into clay in a kneading machine. After aging, it forms plastic clay material. The material is extruded into clay strips in an extruder. Then, it is cut into clay segments with equal length and diameter. Then, they are put into a ball rolling machine to roll into ball blanks.
The direct powder rolling method. The process is simple. First, use a rotating ball machine, which is simple and cheap. Add pre-made ball blank crystal seeds. Then, rotate the machine and spray water mist while adding ceramic powder. The powder continuously sticks to the crystal seeds’ surface and grows. Finally, we obtain the required size of ball blanks.
Dropping
For very small zirconia grinding balls (from 0.05mm to a few tenths of a millimeter), you can use the titration method to form ceramic ball blanks. The zirconia ceramic balls produced by the titration method can be sintered at low temperatures. They have no internal pores and possess high density, strength, toughness, and low wear.

Quality Control and Testing in Manufacture
Appearance Inspection
It is one of the most common Zirconia Grinding Ball inspection methods. Check whether the surface of zirconia grinding balls is smooth and even, with no defects such as breakage, cracks or stains.
Particle Size Analysis
The particle size distribution and average particle size of Zirconia Grinding Balls are measured by means of tools such as optical microscopes, electron microscopes or particle size analysers. This can help determine the quality of preparation and processing of zirconia grinding balls.
Hardness Testing
Conduct Rockwell or Vickers hardness tests to measure the hardness of the Zirconia Grinding Balls. This is crucial for assessing their ability to withstand abrasion and maintain their integrity during grinding processes.
Density Measurement
The density of Zirconia Grinding Balls is usually measured by the gas specific gravity method or the liquid displacement method. This verifies that the composition and preparation process meet the requirements.
Crystal structure analysis
Determine the crystal structure and lattice parameters of the Zirconia Grinding Ball through techniques such as X-ray diffraction (XRD). This verifies that it is of high purity and has an intact crystal structure.
Microstructural Analysis
Employ scanning electron microscopy (SEM) to examine the microstructure of the Zirconia Grinding Balls. This detailed analysis helps confirm the uniformity and integrity of the zirconia material, ensuring quality and consistency.
Wear Resistance Testing
Conduct wear tests on the grinding balls using methods like the Taber Abrasion test. This evaluates the balls’ wear resistance over time, essential for durability and consistent grinding efficiency.
Impact Resistance Testing
Conduct Charpy or Izod impact tests to evaluate the impact resistance of the grinding balls. This ensures that the balls can withstand the forces encountered during grinding without breaking or deforming.
Corrosion Resistance Testing
Perform corrosion tests to assess the resistance of Zirconia Grinding Balls to chemical corrosion in specific environments. This is particularly important for applications where the balls may be exposed to corrosive substances.
