Abstract
A fluidized bed jet mill for grinding particulate material including a jetting nozzle comprising: a first hollow cylindrical body with a first diameter, wherein one end of the body is directed towards the center of the jet mill and the other end traverses the wall of the jet mill; and a hollow cylindrical curvilinear body with a diameter which is less than said first diameter, wherein the first end of the curvilinear body is collinear with the long axis of said first hollow cylindrical body, wherein the first end of the curvilinear body is at a point approximately equal to the end of the first hollow cylindrical body, wherein the second end of the curvilinear body passes through an opening in the side wall of said first hollow cylindrical body, and wherein said side wall opening is leak free and resides within the grinding chamber of the fluid bed mill; and wherein the nozzle communicates the gas stream from a high pressure source to the grinding chamber.
