High purity natural Brazilian agate ball mill grinding jars, highly
wear-resistant and resistant to acids (except HF) and solvent,
these jars are used whenever small quantity of samples need to be
grinded without contamination. Each jar set includes grinding jar,
lid, rubber sealing gasket and mixed agate grinding balls. The
grinding jars are extensively applied to in the fields of Ceramics,
Electronics, Light Industry, Paint, Ink, Medicine, Food, Geology,
Chemical Engineering and so on.jar lid, silicon sealing gasket and
different sizes of mixed stainless steel grinding balls.

Choice of Grinding Jars & Grinding Balls
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.
