This post is a repository. Tried ball milling AP to get a bimodal AP particle distribution for a 80% solids (barely) pourable formula.

• Lortone 45C ball mill
  • Container: 1500ml // 1,5liter
  • Ceramic grinding media 20mm balls – 1400gr is approx 750ml
• Lortone 45C ball mill loading instructions:
  • 1/2 full of milling media
  • 1/4 full of chemicals.
  • First fill empty mill jar with one-quarter full of chemicals (one-quarter = 375ml = approx 700gr AP or KNO3) than load with approximately 1400gr grinding media.

20240329 – AP ball milling:

• Lortone 45C ball mill
• 1380gr of ceramic grinding media 20mm balls
• 800gr of 200um spherical AP (considered heavy loading not 25% but 28% loading with AP)
• 1, 2 & 3 hours run time.
• 1hr – fine crystals

20211017 – For BKNO3.

• Lortone 45C ball mill
• 1400gr of ceramic grinding media 20mm balls
• 300gr of KN
• 1hr run time.

AP ball milling:

• Lortone 45C ball mill
• 1840gr of ceramic grinding media 20mm balls
• 500gr of 200um spherical AP
