Grinding Balls (Grinding Media)

Grinding balls are the media that move inside the ball mill jar to crush and grind the sample. Because they directly determine grinding efficiency and sample purity, the ball material must be selected according to the material being ground and the jar in use. Stainless steel, alumina, agate, zirconia, tungsten carbide and polyurethane options differ in hardness, density and contamination risk.

Key Features

• Six material options: stainless steel, alumina, agate, zirconia, tungsten carbide, polyurethane
• Available in various diameters; a mix of several diameters usually gives the best grinding result
• Ball material should be matched to the jar material to avoid metal contamination
• Zirconia and tungsten carbide offer high density for fast and fine grinding
• Agate and alumina suit work where metal contamination is not acceptable
• Polyurethane is preferred for soft materials and contamination-sensitive applications
