The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and nonferrous metals. The ball mill can grind various ores and other materials either wet or dry.
The utility model relates to an internal vibration feeding hopper. A shell body of an outer cone of the feeding hopper is fixed, the inside of the outer cone of the feeding hopper is provided with a supporting rack, an activating cone can be movably supported and arranged on the supporting rack, and the activating cone is connected with a motor of a vibration source.
