Product Q&A

Q:What material are agate grinding balls? What is their hardness?

They are made of natural agate with main composition of Sio2, Mohs hardness is 7 and density is 2.65g/cm3.Featuring low metallic impurities, they are perfect for samples sensitive to metal contamination.

Q:What standard sizes do you offer? Are custom sizes available?

Standard sizes :3mm,4mm,5mm,6mm,8mm,10mm,12mm,14mm,16mm,20mm,custom sizes can be supported

Q:Will agate balls bring contamination to samples?

slight SiO2 wear particles are unavoidable.For optimal performance ,please use agate balls together with agate grinding jar ,Do not mix with jars of other materials.

Q:What causes cracking or breakage of agate balls during grinding?

Main reasons: empty-jar operation ,too high rotating speed, grinding super-hard samples ,hidden micro-cracks caused by collision. Please remove all broken fragments timely to prevent scratching jar inner wall.
