A method for making abrasive grains, the method comprising mixing one or more solids with one or more liquids in a twin screw extruder to form a mixture, transferring the mixture to a high pressure piston extruder; and extruding the mixture from the high pressure piston extruder through a die to form an extrude. The method further includes segmenting the extrudate to form extruded shaped abrasive particles.
