Ball mill media type posted in Tools and Tooling: It has been a while since I last posted on this forum. The ball mill I made works better than expected( 2 hours mill time max). Running a 6 jar with 60 cal lead balls at a good 70 rpm. I make strictly bp for a small cannon. Question I have is I want to make a couple of jasr to mill charcoal/sulfur together and then the other jar just for ...

Planetary Ball Mill PM 400. The PM 400 is a robust floor model with 4 grinding stations and accepts grinding jars with a nominal volume from 12 ml to 500 ml. It processes up to 8 samples simultaneously which results in a high sample throughput. The extremely high centrifugal forces of Planetary Ball Mills result in very high pulverization ...

The objective of this research is to study the effect of water content on particle characterization and agglomeration of bamboo charcoal resulted from ball milling process. The characterization is determined by the particle size and the morphology of the particle. The milling was performed in cylinder vial of stainless steel. The element of milling is steel balls. The dimension of the cylinder ...

The contamination from milling charcoal with lead was certainly significant. The performance was quite good, considering that 4% of the charcoal weight in the 751510 was displaced by the contamination. Even though the powder was good, the flight times were the lowest of all powders tested. ... The flights of the ball did become somewhat more ...

This study successfully prepared a novel sulfurdoped nano zerovalent iron biochar (BMSnZVIBC) by modifying corn stover biochar with Fe 0 and S 0 using a mechanical ball milling method for effective phosphorus (P) adsorption in the waterbody. Batch experiments revealed that BMSnZVIBC (BC/S 0 /Fe 0 = 3:1:1) reached a Q max of mg P/g and followed PFO and Langmuir models.

If one is milling only individual chemicals like charcoal or potassium nitrate, then any of these media are safe for crushing it. It is when one gets into milling mixed compositions like black powder that the dangers arise. We simply don't want sparks generated in the mill jar during that process for obvious reasons.

Herein, novel Febiochar composites (MBC BM500 and MBC BM700) were synthesized through K 2 FeO 4 copyrolysis and ball milling, and were used to eliminate Cr(VI)/TC from water. Characterization results revealed that higher temperature promoted formation of zerovalent iron and Fe 3 C on MBC BM700 through carbothermal reduction between K 2 FeO 4 and biochar. The higher specific surface area and ...

The key is the charcoal and the milling method. I start with 10 or 12 mesh charcoal, and mill it with stainless steel media. Ceramic may be better for allowing a cheap mill to turn, but it's the least efficient of the common media types. I would never use lead for milling charcoal by itself, but for milling BP, hardened lead wears very slowly.
