Abstract
A system for milling at least one material, e.g., a drug, is described. The system includes a milling apparatus. In another embodiment of the invention, the system includes at least one milling medium. The milling apparatus includes a chamber having a rotary milling head located in it. The milling head is rotated within the chamber by a magnetic drive system.
Claims56
A system for milling at least one material, said system comprising a milling apparatus, said apparatus comprising:
- (a) a milling chamber, said milling chamber comprising a hollow vessel for receipt of the at least one material;
- and
- (b) a drive member, said drive member including at least one drive magnet, and said drive member being arranged to be rotated by an energy source,
- (c) a milling head, said milling head being located within said milling chamber, being rotatably mounted with respect thereto, and including at least one driven magnet, said at least one drive magnet being magnetically coupled to said at least one driven magnet;
- whereupon rotation of said drive member effects the concomitant rotation of said milling head with respect to said milling chamber, to effect the milling of the at least one material within said milling chamber.
2 more elements
A method for milling at least one material comprising:
- (a) providing a milling chamber having a milling head located therein;
- (b) providing the at least one material in said milling chamber;
- (c) providing at least one milling media in said milling chamber;
- (d) providing a shaft arranged to be rotated about a longitudinal axis by a source of energy;
- and
- (e) magnetically coupling said shaft to said milling head to rotate said milling head about said axis in said milling chamber, whereupon rotation of said shaft about said axis effects the concomitant rotation of said milling head to effect the milling of the at least one material within said milling chamber.
