An impact mill including a base portion on which is disposed a rotor rotatably mounted in a bearing housing, the rotor having an upwardly aligned cylindrical surface portion coaxial with the rotational axis. The impact mill is provided with a mill casing within which is located a conical track assembly which surrounds the rotor to form a conical grinding path. The mill casing is provided with a downwardly aligned cylindrical collar which may be axially adjusted to set a grinding gap between the rotor and the mill casing. The rotor is provided with a plurality of impact knives complementary with a plurality of impact knives disposed on the inside top surface of the mill casing. In addition, the impact mill can be formed of separated conical sections. Finally, power is transmitted to the rotor of the impact mill by a synchronous sprocketed belt, accommodated by a sprocketed drive sheave, wherein the belt is in communication with a power source.
An impact mill comprising a base portion upon which is disposed a rotor rotatably mounted in a bearing housing, said rotor having an upwardly aligned conical surface portion coaxial with the rotational axis, said impact mill provided with a mill casing within which is located a conical track assembly which surrounds said rotor to form a conical grinding path, said mill casing having a downwardly aligned cylindrical collar which may be axially adjusted to set a grinding gap between said rotor and said mill casing, a substantially horizontal top surface of said rotor provided with a plurality of impact knives complementary with a plurality of impact knives disposed on a substantially horizontal inner housing surface of said mill casing.
