CONICAL-SHAPED IMPACT MILL.

摘要

An impact mill (100) including a base portion on which is disposed a rotor (3) rotatably mounted in a bearing housing, the rotor having an upwardly aligned cylindrical surface portion coaxial with the rotational axis. The impact mill includes a mill casing within which is located a conical track assembly (5) surrounding the rotor to form a conical grinding path. The mill casing includes a downwardly aligned cylindrical collar (11) which may be axially adjusted to set a grinding gap (S) between the rotor and the mill casing. The rotor includes a plurality of impact knives complementary with a plurality of impact knives disposed on the inside top surface of the mill casing. The conical track assembly (5) can be a series of assembled conical sections or one unit with varied number of serrations in either a vertical or sloped configuration. This flexibility allows for greater compatibility with the feedstock being milled.
