Once the centrifuge has the out-of-limit amplitude, the upper chute and the lower chute can immediately return to the shape even if being in collision contact, so that the deformation and the damage can not be caused. Therefore, the application of the first buffer unit changes the upper chute from a rigid body to an elastic body, and has a special absorption effect on very vibration in operation. On the other hand, due to the application of the first buffer unit, the side wall of the upper chute can be made to be small in inclination angle, the gap reservation between the upper chute and the lower chute is small, and the problems that the side wall of the upper chute is too large in inclination angle, materials are stuck to the side wall of the chute, even bridging and blocking are caused, and accordingly the upper separation equipment is damaged are effectively avoided.

Once the centrifuge has the out-of-limit amplitude, the upper chute and the lower chute can immediately return to the shape even if being in collision contact, so that the deformation and the damage can not be caused. Therefore, the application of the second buffer unit changes the lower chute from a rigid body to an elastic body, and has special absorption effect on the very vibration in operation. On the other hand, due to the application of the second buffer unit, the gap between the upper chute and the lower chute can be reserved very little, and the problems that materials are stuck on the side walls of the chutes, even are bridged and blocked due to overlarge inclined angles of the side walls of the upper chute, and the damage to the upper separation equipment is caused are effectively avoided.

The flexible connecting device and the external equipment are difficult to position when being installed. And because the relative position of the upper chute and the lower chute caused by installation is unreasonable, the effective elastic range of the flexible connection structure can be greatly reduced, even the upper chute and the lower chute collide when the equipment runs, or the material of the flexible protective sleeve is torn. To this end, we have designed 4 or more distance posts that connect the upper and lower mounting flanges configured for mounting.
