Technical Field

[0001] This utility model relates to the technical field of catalyst recovery, and in particular to a ball mill for deactivated catalyst. Background Technology

[0002] The mill is a key piece of equipment for further grinding materials after they have been crushed. It is widely used in the production industries of cement, refractory materials, fertilizers, ferrous and non-ferrous metal ore beneficiation, and glass and ceramics, for dry or wet grinding of various ores and other grindable materials.

In use, the waste molybdenum to be recovered and separated is... Ferric molybdenum catalyst is fed into the ball mill through the inlet. The drive motor drives the ball mill via the transmission rod to mill the catalyst inside. After being milled to a certain particle size, the catalyst is fed into the tank through the material connection pipe. Then, caustic alkali is injected into the tank through the liquid injection port. The electric heating tube is controlled by the control button to heat the waste ferric molybdenum catalyst in the tank at high temperature to remove sodium, thereby separating and recovering molybdenum and chromium from the waste catalyst.
