Processing system and method with a single variable rpm mill for manufacturing spheroidized graphite powder

A system for manufacturing spheroidized graphite powder, the system comprising:

• a feeder adapted to convey primarily crushed particles to a grinding section enclosed in a chamber;
• a first classifier located at the top portion of the chamber, the first classifier is configured to receive the milled particles and adapted to separate the milled particles into a first particle and a second particle;
• one or more motors coupled to the grinding section and the first classifier, the one or more motors operated to be rotated at a progressively variable frequency from high to low or low to high revolution per minute;
• and
• a controller operatively coupled to the one or more motors, the controller configured to:
• operate, the one or more motors, with progressively varying RPM, at high RPM to cut the rough edges of the particle to form the first particle pertaining to a fine graphite particle;
• and
• operate, the one or more motors, with progressively varying RPM, at low RPM, to smoothen the surface of the particle to form the second particle pertaining to spherical graphite particle.
