lab coal grinding planetary ball mill
The DECO-PBM-V-0.4L has four ball grinding jars installed on one turning plate. When the plate rotates, the jar axis makes the planetary rotation in opposite directions and the balls in the jars grind and mix samples in high-speed movement. The product can smash and blend various products of different materials and granularity with dry or wet methods. (Note: granularity of grand products is dependent on the material properties, size, and quantity of milling media and processing time. According to customer's feedbacks, minimum granularity can be as small as 0.1 um).
1. How to choose the right jar 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.
2. Is it necessary to use zirconia jars with zirconia beads?
It depends on why you are using zirconia beads as the grinding media. If the purpose is to avoid metal contamination, you should use zirconia, alumina, or agate jars. If the purpose is to use the hardness of zirconia to break up materials, stainless steel jars are fine. Although zirconia is much harder than stainless steel, these beads won't damage the jars.
