Paper Title:
Design of a Machine by Low Cost and the High Performance for Produced Powder Materials
  Abstract

Mechanical alloying and mechanical fine grinding processes are mostly based on the high energy milling technique. Equipment of a horizontal high-energy ball mill that has been developed in the Cefet-BA is a low cost machine with high performance. These milling machines are equipped with a cylindrical stainless steel horizontal container. Inside the container, a chamber of water circulation is used to maintain, powdered materials, the room temperature. The grinding container inside to chamber horizontal container is a container, cylindrical stainless steel, opened of the two sides. The container with the powder particles is a sealed of two sides and vacuum out-gassed is realized. A motor driven rotor is used to accelerate the grinding media and the milling process is realized due to the ball to ball/rotor/wall impacts as their kinetic energy is transferred into the powder which is randomly located between the colliding balls. The rotor milling machine equipment permits two rpm e.g. 500 and 1500 rpm. Machines based on this design from lab scale (3.0 liter volume), mainly to develop new powders and materials.
