설명

8-9mm Pressureless Sintered Silicon Carbide Grinding Balls
Product Overview
Pressureless sintered silicon carbide grinding balls are precision ceramic grinding media produced from high-purity, ultrafine silicon carbide micropowders via high-temperature pressureless sintering at 1950-2150°C in a non-oxidizing atmosphere.
Diameter Range Typical Equipment Position of 7-8 mm Balls
0.5-2 mm Ultra-fine stirred mills Ideal for ultra-fine grinding
2-8 mm Stirred mills Combines low density with high hardness
7-8 mm Stirred mills / medium-to-large grinding equipment High impact energy and packing load
8-15 mm Tumbling ball mills Conventional grinding media

Core Performance Parameters
Physical and Mechanical Properties
Parameter Typical Value Remarks
SiC content ≥98% - 99% High-purity pressureless sintering
True density ≥3.15 g/cm³ PS-SiC >3.15; reaction-bonded >3.02
Vickers hardness (Hv) 2000-2500 Far exceeds ZrO₂ and Al₂O₃
Rockwell hardness (HRC) 85-90 Higher than most metals and ceramics
Compressive strength >2500 MPa High mechanical strength
Wear rate ≤0.01‰ Extremely low wear
Maximum service temperature 1600 °C Long-term service in oxidizing atmosphere
Engineering Significance: The combination of "lower density + ultra-high hardness" provides unique technical and economic advantages in medium-material grinding applications.

Comparative Performance Analysis
Parameter PS-SiC ZrO₂ Al₂O₃ Steel (GCr15)
Density (g/cm³) 3.15 6.0 3.6-3.95 7.8
Vickers hardness (Hv) 2000-2500 1100-1300 1800 ~800
Max. service temperature (°C) 1600 400 1000 ~400
Corrosion resistance Excellent Good Good Poor
Wear resistance Excellent Good Medium Low
Industry data: Service life of SiC grinding balls can be up to 35 times longer than conventional grinding media.

Size-Specific Performance
Technical Advantages of 7-8 mm Balls
  • Moderate and controllable impact energy: Higher single-ball impact energy for crushing medium-sized particles
  • High packing efficiency: Optimal balance of impact frequency and contact area
  • Good compatibility with graded charges: Can be used with smaller balls for optimized distribution
  • Excellent screen compatibility: Less likely to block discharge screens in continuous production
Typical Applications
Application Area Specific Use Advantages
Ultra-fine grinding of hard materials Fine grinding of superhard powders (SiC, B₄C, TiC, Si₃N₄) High grinding efficiency and product purity
Ceramic raw material grinding Crushing and homogenizing alumina, mullite, quartz Very low wear and minimal contamination
Paint and coating production Dispersion of high-hardness fillers Non-magnetic and chemically inert
Refractory material processing Fine grinding of refractory raw materials Service life exceeding 8000 hours

Manufacturing Process
Process Step Key Parameters Influence on Performance
Raw material preparation High-purity SiC micropowder (≤1-2 μm) Determines sintering driving force and final density
Rolling forming Dynamic rolling granulation Determines green ball size and sphericity
High-temperature pressureless sintering 1950-2150°C, inert atmosphere Determines density, hardness, and fracture toughness
Rough grinding and finishing Double-disc grinding / precision polishing Ensures surface smoothness and high sphericity (≥0.96)
