Described front shroud is a hollow cylinder flange, and a front axle is housed in the flange, preceding shaft rear end and the socket of screw shaft front end; The front axle front end is connected with the ball bearing tight fit, bearing outer ring and front shroud flange place internal diameter close-fitting suit, and front axle is equipped with two sealing rings outward; Between two sealing rings certain interval is arranged; On the gap location front shroud, through hole is arranged, snap joint is housed on the through hole, insert compressed air; Compressed-air actuated pressure makes two spaces between the sealing ring keep certain pressure, and powder material can not be leaked to bearing portion; The opposite side of two sealing ring gap location front shrouds is equipped with a silencer simultaneously, plays the effect that reduces noise; Front shroud front end boss end face tightens up with screw through cover plate.

One control cabinet is loaded on the underframe, and the gripper shoe side is connected with electric equipment with power line.

The invention has the beneficial effects as follows:

1, the branch screen capacity height that revolves of the present invention per hour can sieve the powder material about 2000kg;

2, be provided with two material discharging openings, one of them is the auxiliary discharging opening of powder particle greater than sieve number, is convenient to the processed once more of material;

3, be convenient to loading and unloading, the convenient cleaning on the structural design;

4, the screen cloth that disposes plurality of specifications is used for the screening of different material;

5, the pressurized seal structure of uniqueness solves the leakage problem that powder equipment exists usually.
