Coffee Mill. A coffee mill does a job similar to a blender but it works a little better. You can grind a little at a time but it does a better job of keeping the material pulled into the blades. It was designed to grind solids so it is a better choice. A new coffee mill (a cheap one) can be purchased for about $15.

Description of the novel perchlorate-reducing bacteria

Introduction. Perchlorate has been widely used as an oxidant in munitions propellant as well as other applications and, due to its competitive inhibition of iodine uptake in the thyroid gland, can cause decreased levels of thyroid hormone production (Wolff 1998).As a result of unregulated disposal of the compound prior to 1997, perchlorate …

Perchlorate fuse.

Well you can simply make Black Powder with the same proportions but swapping the Potassium Nitrate for Potassium Perchlorate BUT you shouldn't mill or grind it at all and it will be rather a bit more sensitive given the Potassium Chlorate impurity your Potassium Perchlorate is likely to contain. So screen the powder together using a 40ish …

Ammonium perchlorate

Ammonium perchlorate is one oxidizer that I have not experimented with... yet. I picked up a couple pounds of the mixed mesh stuff from Firefox. ... If its coated, or bound without water you should be fine. It is fine to mill, but it increases burn speed. Good AP shouldn't clump too bad, less than KP for sure. It is skin irritant to some extent ...

Effect of Ammonium Perchlorate Particle Size on Flow, …

The coarse particle size depends on crystallization conditions. It is stable, nonhygroscopic, reasonably high performing, and quite safe to handle. Part of coarse AP is ground in an air-classifying mill, hammer mill, and fluid energy mill to reduce the particle size and is used along with coarse AP in propellant composition.

Ammonium perchlorate has been pulverised by an impact mill (air classifier mill) to study the influence of different operating parameters, viz., effect of mill speed, classifier speed, feed rate ...

Perchlorate in Drinking Water | US EPA

Perchlorate is a naturally occurring and manufactured chemical anion. On February 11, 2011, EPA determined that perchlorate meets the Safe Drinking Water Act criteria for regulation as a contaminant.

Coffee Grinding questions, need expert knowledge!

Get separate mills for nitrate and perchlorate, and only ever mill fuels in the mill that is only used with nitrate. Do this outside away from other pyro compositions. There have been plenty of ignitions of fuels and electrical fires in coffee mills and other electronic tools even without an oxidizer present. Some of them have ended up being ...
