ammonium perchlorate grinding by hammer mill

Ammonium perchlorate (AP)-based composite propellant has been widely used as a solid propellant, but higher burning rates are in demand. We report that crystal-habit-modified AP is an effective oxidizer that increases the burning rates of propellants...SUBSTANCE: invention relates to grinding solid materials, including ammonium perchlorate, to obtain particles with size from 80 nm to 500 nm, used in production of composite solid propellant. Disclosed is a method of producing finely dispersed ammonium perchlorate with particle size from 80 nm to 500 nm for composite solid propellant.

AP Ammonium perchlorate BTTN 1,2,4-Butanetriol trinitrate ... The second was obtained by grinding AP in a fluid energy mill to an average particle size of around 1-5 μm. Coated ADN particles ... determined by applying the fall hammer method (2 kg drop weight) with 30 mg...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 …

Ten pounds of unground ammonium perchlorate (180) was added to the Vibro-Energy Mill which contained 42 lbs. 12 oz. of FREON-113 (1, 1, 2 - trifluoro - 1, 2, 2-trichloroethane) and 200 lbs. of 1/2 inch × 1/2 inch alumina cylinder grinding media. 22-7 grams of butylene imine adduct of divinylbenzene in 150 ml methylene chloride was then added ...American Institute of Aeronautics and Astronautics 12700 Sunrise Valley Drive, Suite 200 Reston, VA 20191-5807 703.264.7500

Perchlorate black powder is a simple and unoptimized variant of Standard black powder obtained by replacing the Potassium nitrate with Potassium perchlorate.No mixtures of a fuel and Potassium perchlorate can be processed in a ball mill nor rammed via hammer. Therefore the chemicals must be as a fine powder prior to the mixing process...Ammonium perchlorate grinding ladonatellabe ammonium perchlorate grinding by hammer mill ammonium perchlorate is a white crystalline solid or powder classified as a division explosive if powdered into particles smaller than microns in diameter or if powdered into larger particles but thoroughly dried more ammonium perchlorate grinding mill china.

1. A method for preparing ultrafine particle size ammonium perchlorate that has weight median diameters ranging from about 0.25 to about 5.0 micrometers and that is coated with an aziridine compound, said method comprising: i. charging a predetermined amount of unground ammonium perchlorate into a vibro-energy grinding mill;...Coffee Grinding questions, need expert knowledge! - posted in Pyrotechnics: I have just got some new pyro chemicals and the oxidisers are all granular/ sugar like. I have potassium perchlorate, potassium nitrate, and potassium chlorate. I have ordered a coffee grinder to mill the chemicals down to a usable mesh. I've heard of (per)chlorate / nitrate incombatibilities, can …

1.. IntroductionProperties of ammonium perchlorate in general and particularly its thermal decomposition have been a subject of extensive literature including reviews,,,, .. It was revealed during investigation of thermal decomposition of ammonium perchlorate that the process is characterized by a number of features which were of purely scientific interest irrespective of …...Our Micro-Jet is typically used to grind oxidizers, such as Ammonium Perchlorate. Mineral and Pigment Grinding A Fluid Energy Model 0808 Jet-O-Mizer utilizes 1,200-2,200 SCFM of air compressed to 100 psig for mineral and pigment grinding.

Ammonium perchlorate was grinded up and activated in an Activator-2SL planetary mill (Company "Activator", Novosibirsk ) with steel balls and grinding bowls. Activator-2SL has two drums with a volume of 250 ml, the speed of rotation of the planetary disk is 1000 rpm, the speed of rotation of bowls is 1500 rpm...As shown by experimental work on grinding ammonium perchlorate on jet mills, achieved the minimum size of the particles only at the level of 6 μm (specific surface area of 5000 cm 2 /g). While the crushed fraction of ammonium perchlorate exit from the apparatus in the form of small balls, then there is a aggregation of particles (initial stage ...

(ammonium perchlorate, AP) and a metallic fuel (aluminium powder, ... (India). A pin disc mill (ACM-10) was used to prepare 50μm AP by grinding 300 μm AP. HTPB, having an average molecular weight of 2560 and hydroxyl number 41.8 mg KOH/g, ... fall hammer instrument, OZM make (model No. BFH-10) with...AP. Upon opening the jar some hours later after milling, the AP has. been milled to a much finer powder, but is now almost completely stuck. to the insides of the jar. The layer is very hard, and is difficult. to remove. The inner surface of the jar is unvarnished porcelain, which is relatively rough.
