[0047] Working principle: When sieving the fused zirconia particles, firstly, the fused zirconia particles are placed inside the arc screen box 8 through the gap between the fixed box 1 and the two baffles 7. The sieve holes on the arc screen box 8 will sieve the fused zirconia particles. Then, the two motors 5 are started to rotate forward and reverse continuously.
