  • Agate Grinding Balls for Lab Planetary Ball Mill

Short Description:

Agate is a microcrystalline variety of silica, chiefly chalcedony, characterised by its fineness of grain and brightness of colour. 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 30mm. The grinding media balls are extensively applied to in the fields of Ceramics, Electronics, Light Industry, Medicine, Food, Geology, Chemical Engineering and so on.

Advantages

Highly polished, smooth, easy to clean, low abrasion to the equipment.

High mechanical strength, good toughness, impact resistance, no broken beads.

In order to prevent excessive abrasion, the hardness of the grinding jars used and of the grinding balls must be higher than that of the material used. Normally, grinding jars and grinding balls of the same material should be chosen.
