Abstract
Fast grinding is a growing need in the technological industry, several methods and equipment provide this service, such as the planetary mill, which is a centrifuge machine that combines rotation and revolution. It optimizes and increases power of both milling mechanism: friction and mechanical shock, therefore being considered a high-energy process. Planetary mill based on friction wheels transmission was designed and a prototype was built and performed. Different friction wheels materials were tested. The grinding was performed through milling of a coarse calcined alumina powder, where was experimented different combinations of transmission ratio, revolution speed, material of the jar and ball (media) size. Tempered steel presented the best durability and reliability as friction wheel. Optimized design and experimental configuration of alumina milling resulted in sub micrometric powder in just 1 hour. The transmission based on frictional wheels permitted an economical and compact design, presenting high performance and safety.
