Projecting one jet of particles against another is one way to overcome the problem of wear on the impact anvil. This method was introduced by Willoughby in 1917 [8] and is the basis of the Majac mill. The feed product is swept round the grinding chamber and through the two phase (air+particles) nozzles to impact each other until the particles are fine enough to leave through the centrifugal ...
