500ml Vacuum/ Inert gas grinding jar, planetary ball mill use
Grade 304 is the most widely used austenite steel, also known as 18/8 for its composition of 18% chromium and 8% nickel. 304 may be referred to as A2 stainless (not to be confused with A2 grade steel, also named Tool steel, a steel). The grinding jars are extensively applied to in the fields of Metallurgy, Electronics, Construction Material, Ceramics, Chemical Engineering, Light Industry, Medicine, Environmental Protection, Paint, Ink, Geology and so on. Each jar set includes grinding jar, jar lid, rubber sealing gasket, 6pcs inner hexagon screws, 2pcs vacuum valve and different sizes of mixed stainless steel 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.
Grinding Jar Ball Configurations
|Grinding Jar Volume|
Compatible Ball Weight
Φ5 mm (0.52 g/pc)
Φ10 mm (4.15 g/pc)
Φ15 mm (14.00 g/pc)
Φ20 mm (33.20 g/pc)
These values are just clues: the number of the balls should be determined experimentally if necessary.
How to choose the right jar:
The ball mill jars are chosen according to the raw material. The general rule is the jar must be harder than the material being milled. Most times stainless steel is sufficient, if the material can react with metal, then agate is good. Otherwise, zirconia is common.
