Abstract：
 The ball milling unit has one increased small inner cylinder coaxial with the outer cylinder, grinding medium filled in the space between the inner cylinder and the outer cylinder and cooling medium introduced into the inner cylinder to cool the milling unit. The present invention isolates the ineffective grinding space in the central part, alters the motion regulation of grinding medium balls, reduces or eliminates the immobile layer of medium balls and makes more medium balls in moving grinding state, so as to raise the grinding efficiency, reduce power consumption and raise grinding quality.
