20 mm Agate Milling Media Balls, 1 kg
Natural Brazilian Agate Grinding Media Balls Density: 2.65g/cm3 Shape: sphere Available Diameter: 3mm~30mm Description for 20 mm Agate Milling Media Specifications High purity natural Brazilian agate (97.26% SiO2) grinding media balls, highly wear-resistant and resistant to acids (except HF) and solvent, these balls are used whenever small quantity of samples need to be grinded without contamination. Different sizes of agate grinding balls available: 3mm to 20mm. The grinding media balls are extensively applied to in the fields of Ceramics, Electronics, Light Industry, Paint, Ink, Medicine, Food, Geology, Chemical Engineering and so on. Features High purity, low contamination to the samples High cost-effective, low wear and long lifetime High specific gravity, high grinding efficiency Highly wear resistant to acid and solvents Highly polished, smooth, easy to clean, low abrasion to the equipment High mechanical strength, good toughness, impact resistance, no broken beads Mainly used for lab planetary ball mill machine Use of the Milling Media Balls Pregrinding the coarse, hard material with large balls Use of many small balls will increase the fine fraction if the running time is increased A higher mass (spec. weight) of the grinding balls will accelerate the grinding Size of the Grinding Balls Type of feed material Ball diameter Hard samples feed particle size <10 mm 30 mm or 40 mm Medium piece size (<5 mm) 20 mm Fine material (0.5 mm) 10 mm or 5 mm Homogenisation of dry or liquid samples 10 mm Homogenisation of viscous samples 20 mm These are recommendations: the size of grinding jars and grinding balls should be determined experimentally if necessary.

Features
High purity, low contamination to the samples
High cost-effective, low wear and long lifetime
High specific gravity, high grinding efficiency
Highly wear resistant to acid and solvents
Highly polished, smooth, easy to clean, low abrasion to the equipment
High mechanical strength, good toughness, impact resistance, no broken beads
Mainly uséd for lab planetary ball mill machine
Use of the Milling Media Balls
Pregrinding the coarse, hard material with large balls
Use of many small balls will increase the fine fraction if the running time is increased
A higher mass (spec. weight) of the grinding balls will accelerate the grinding
