Claim:
An ultrafine material crusher system comprising: a. a crusher body with an openable lid and an outlet; b. a feed tube disposed through the openable lid for receiving particulate and forming a particulate flow; c. a rotating centrifugal multiport assembly disposed within the crusher body and in fluid communication with the feed tube, wherein the rotating centrifugal multiport assembly comprises: (i) a rotating circular plate with a plate perimeter; (ii) a plurality of ports equidistantly located along the plate perimeter; (iii) a well centrally disposed in the rotating circulate plate for receiving the particulate flow from the feed tube at an angle between eighty degrees and one hundred degrees and then flowing the particulate flow to the plurality of ports at a velocity of up to five hundred feet per second; (iv) a plurality of abrasion resistant sleeves disposed in each of the plurality of ports, wherein each abrasion resistant sleeve has a hardness rating of at least eight on the MOHS hardness scale; and (v) a locking means for holding the plurality of abrasion resistant sleeves in each of the plurality of ports; d. a direct drive motor connected to the rotating centrifugal multiport assembly for accelerating, running, decelerating and stopping the rotating circular plate, wherein the rotating circular plate forms a high velocity particulate while it accelerates and runs, and wherein each of the abrasion resistant sleeves passes the high velocity particulate from the rotating circular plate out of the rotating centrifugal multiport assembly; e. a variable frequency drive connected to the direct drive motor for optimizing rotation speed of the rotating circular plate, preventing over crushing of particles in the high velocity particulate, and preventing creation of waste product; f. an anvil ring assembly comprising: (i) an anvil ring; (ii) a plurality of anvil holders disposed equidistantly around the anvil ring; and (iii) a plurality of removable anvils each having an anvil face, wherein each removable anvil is disposed in one of the anvil holders allowing each anvil face to be impacted at an angle by the high velocity particulate, and wherein a downdraft carries the high velocity particulate from the anvil faces downward to the outlet in the crusher body; g. a gas purge system for pressurizing a shaft bearing on the direct drive motor enabling continuous use of the system.
