XJ type mechanical agitating flotation machine can be widely used in ferrous metal minerals such as iron, rough selection, selection, sweeping and reverse flotation of non-ferrous metals and non-metallic minerals such as copper, lead, zinc, antimony, molybdenum and gold. However, it is not suitable for rough selection and sweeping operations in large flotation plants.

Features
1.It can imbibe the air and ore pulp spontaneously;
2.It is easy to return the middlings for realizing gravity flow, with no auxiliary equipment required;
3.Its configuration is in good order with easy and simple operation and maintenance;
4.It has the disadvantages like small air injection amount and high electricity consumption;
5.Rubber parts are adopted for its impeller and cover plate.

The basic structure of the XJ flotation machine is shown in the figure. It consists of two flotation tanks. The first tank (with the feed pipe) is the suction tank and the second tank is the DC tank. There is a gap between the two tanks. Intermediate room. The impeller is mounted at the lower end of the main shaft, and the upper end of the main shaft has a pulley that is rotated by a motor. Air is drawn in by the intake pipe. The level of slurry in each set of flotation cells is adjusted by the gate. A cover plate and an air cylinder (also called a standpipe) are mounted above the impeller. The air cylinder is provided with a hole for installation into the slurry pipe, the intermediate mine return pipe or as a slurry circulation, and the size of the hole can be adjusted by the tie rod.

It is mainly used to select non ferrous metals such as copper, zinc, lead, nickel, gold, etc., and  also be used for coarse selection and selection of black metal and nonmetal.
