Zirconia Ceramic Parts for Planetary Ball Mills: Achieving Ultra-Fine Grinding with High Durability | CRAC Advanced Ceramics

Introduction: Optimizing Performance in Laboratory and Industrial Grinding

Planetary ball mills are indispensable tools in research and industry for achieving ultra-fine grinding and dispersion of materials. However, traditional grinding jars are often plagued by issues of low wear resistance and material contamination, severely limiting their service life and compromising product purity, especially when processing high-end materials.
Chuangrui Advanced Ceramics (CRAC)​ specializes in high-performance zirconia ceramic solutions that address these challenges. Our Planetary Ball Mill Ceramic Parts, particularly the Zirconia Ceramic Ball Mill Jars, are engineered with exceptional hardness, high toughness, superior wear resistance, and long service life, ensuring efficient and contamination-free processing of ultra-fine materials in a short time.

The Superiority of Zirconia in Planetary Ball Mills

Zirconia ceramic ball mill parts are highly valued for their ability to withstand the extreme mechanical and thermal stresses inherent in high-energy grinding processes.
  1. High Hardness and Wear Resistance:
    CRAC’s zirconia materials, such as the A-ZR, Y-ZR, and PR-ZR series, exhibit extremely high Vickers Hardness, reaching ≥ 1200 HV. This high hardness is directly responsible for the superior wear resistance of the ceramic ball mill parts, ensuring a long service life​ even under continuous, high-impact usage.
    A-ZR Y-ZR Y-ZR-1-1
  2. High Strength and Toughness:
    The materials demonstrate excellent mechanical integrity. For instance, the A-ZR series boasts a Bending Strength of ≥ 950 MPa​ and Impact Toughness of ≥ 20 KJ/m². This high toughness is critical for preventing fracture under the dynamic forces generated by the planetary milling process.
  3. Chemical and Thermal Stability:
    Zirconia ceramic parts show excellent high-temperature resistance and chemical resistance. This stability ensures that the grinding jar materials do not react with or contaminate the processed media, which is essential for maintaining the purity of high-end materials like electronic powders or pharmaceutical compounds.

Optimized Design and Precision Manufacturing

CRAC ensures the high efficiency of its ceramic ball mill parts through both optimized structure design and meticulous manufacturing processes.

Design for Efficient Milling

The overall structure design of CRAC’s ceramic ball mill is reasonable. It incorporates characteristics such as a large arc angle​ and good sealing performance​ of the tank mouth. This design is crucial for ensuring that there will be no material leakage​ or the formation of grinding dead angles​ during use, allowing the mill to efficiently process ultra-fine materials in a short time.

Precision Processing Capabilities

CRAC utilizes advanced machining processes to meet stringent dimensional requirements for ceramic components:
  • Aperture Accuracy:​ 0.01mm.
  • Cylindricity:​ Reaches 0.005mm.
  • Roughness (Ra):​ Reaches Ra0.05.
  • Maximum Size:​ For disc-type parts (relevant to jar lids/bases), the maximum outer diameter is 550mm.

Rigorous Quality Control

To guarantee the quality and stability of each batch of products, CRAC implements strict quality control throughout the production cycle:
  • Raw Material Inspection:​ Includes checking particle size, moisture content, and bulk density.
  • Process Management:​ Involves forming (die pressing, isostatic pressing), green processing, sintering (using different curves for different materials), and precision machining (vertical milling, grinding).
  • Inspection Standards:​ Conventional products are tested by appearance and size specifications, while specific products are tested using UT non-destructive testing​ in the warehouse-in and warehouse-out management process.
