ABSTRACT

To overcome the bottlenecks of powder agglomeration and un-refinement in the ultrafine grinding technology, a two pendulums vibration exciter is designed. Based on the double masses vibration theory, the angel between the two pendulums is adjusted to produce a continuously changing exciting force, which can form high transient vibration intensity and large amplitude. Their transient maximums are 18 and 16 mm respectively. It can effectively deal with powder agglomeration and anti-powder. Therefore, the grinding efficiency is improved. Achievements have been obtained that the output size of diamond particles has reached d(50)≤0.27 µｍ, but the input size is d(50)≤10 µｍ. In addition, the two pendulums spindle strength is checked. Its strength is completely satisfied in the applications.
