Abstract
A method of forming a shaped abrasive particle includes extruding a mixture into an opening in a screen within an application zone and translating the screen and belt to a release zone and separating the screen and belt to form a precursor shaped abrasive particle on the belt, wherein the screen and belt are separated at a release angle of at least about 15° and not greater than about 45°, wherein the release angle is defined as an angle between a surface of the screen and a surface of the belt.
