Upper surface is concordant.
Further, axle sleeve upper surface, the outer upper surface and upper back blades are less than on the outside of the upper primary blades upper surface
Upper surface is concordant.
Further, axle sleeve upper surface edge is along the circumferential direction evenly equipped with multiple screw holes.
Further, the annular groove for installing sealing ring is provided with the axle sleeve upper surface.
Further, the upper back blades is between two adjacent upper primary blades at center.
Further, it is provided with keyway on the axle sleeve.
Compared with prior art, the utility model has the advantages that：
1st, throwing disc itself rigid structure is more stablized, and reduces the vibration of equipment, improves the service life；
2nd, pad is added, eliminates sinking etc. caused by axis pin step is worn so that the abrasion condition of axis pin obtains
Great improvement；
3rd, employ wear-resisting steel plate and make primary blades, and add back blades, improve and get rid of material efficiency and service life；
4th, there is a very big lifting to the overall performance of ring roll mill.
The utility model is described in more detail with reference to the accompanying drawings and detailed description.

Embodiment
Embodiment one：As shown in Fig. 1 ~ 4, a kind of throwing disc, including an axle sleeve 1, the axle sleeve lateral wall lower end are provided with ring
Shape turntable 2, is evenly equipped with several radially arranged upper primary blades 3, adjacent upper main lobe on the disk upper surface circumferencial direction
A radially arranged upper back blades 4 is provided between piece, the length of the upper primary blades is longer than back blades, adjacent upper main lobe
A pad 5 is additionally provided between piece, the inner side of radial direction where the pad is located at upper back blades.
In the present embodiment, the lower pair equal and radially arranged with upper back blades quantity is evenly equipped with the disk lower surface
Blade 6, the inferior accessory lobe piece are located at the underface of upper back blades.When being rotated easy to turntable, inferior accessory lobe piece also produces wind-force, boosting
Air-flow and fine powder preferably enter air-flow and fine powder passage 10.
In the present embodiment, shape of the upper back blades and inferior accessory lobe piece etc. is big.
In the present embodiment, the upper primary blades are inner to be connected with axle sleeve lateral wall.
