At present, the most widely used ball mill in the world contains grid ball mill and overflow ball mill.

Yantai xinhai machinery is one of the ball mill  manufactures who owns the sophisticated technology in domestic.

With the development of mining election, the flotation process has been widely used in the non-ferrous metals, ferrous metals, rare metals and non-metallic mineral processing.

Wet ball mill includes grid wet ball mill and overflow ball mill, and the feeding materials are ore or slurry that is high water content.

Laboratory as the mining equipment in flotation experiment, its quality effect the whole flotation indexes and industrial production.

Its gravity thickener not only could operate stably according to the predicted index, but also can operate simply and flexible after the operation system transformation.
