The utility model has the advantages that:
1. the utility model discloses a sealing device A1 and sealing device B2 because a feed chute and ball mill are connected to an inlet pipe, two sealing device's setting can be guaranteed to all have sealed effect to ball mill feed inlet and feed chute discharge gate.
2. Because the inside of the wet ball mill 4 is provided with steel balls with heavier tonnage, the uncertainty of the gravity center in the operation process causes the wet ball mill 4 to vibrate more greatly, so that the concentricity fluctuation of the base ring 6 and the sealing pipe 7 relative to the feeding pipe 5 is increased, and finally the discharge hole of the feeding groove 3 is sealed and leaks liquid. The utility model discloses a sealing member 8, sealed pad 10 can effectively weaken and absorb partial sealed regional vibration, improve the base ring 6, the concentricity of sealed tube 7 and inlet pipe 5, slag bridge 11 relative hardness is low, but the leakproofness is good, can block a large amount of the sediment material of leaking coming in, and the wearing resistance and the leakproofness of packing 12 can block the more rare material of leakage, symmetrical arrangement base ring 6, sealed tube 7 and slag bridge 11, from the wearing resistance, leakproofness and life have better effect.
