The new grooved annular liner increases the ball ore contact surface, strengthens the grinding effect, and has the ability to lift the ore, reducing energy consumption; the large double-row spherical roller bearing design can greatly reduce the friction and effectively Energy saving 20-30%, and easy to start; the small ball mill with a diameter of 2.1 .

An air inflation mechanical agitation floatation cell with slurry suction, which is featured with strong agitation force, good air spreading effect, uniform mixing of slurry and air, less sedimentary of tailings, low turnaround speed and low power consumption. It can be combined with KYF flotation cell as a joint unit, working as suction cell.

This thickener is a new type thickening equipment independently developed by Xinhai (patent No. 201010521662.5). The thickener is equipped with additional deaerating tank, which can eliminate the solid particles attaching to the bubbles. The feeding pipe is designed under the liquid level, which can effectively prevent gas from entering the ore.

An agitation equipment which forces the slurry to take up and down circulation in the tank. Its umbrella shaped impeller presses the slurry in a downward direction, so that the slurry takes up and down circulation along draft tube, which makes reagents and slurry mix well, strengthens the agitation capacity.

A double stages slurry pump with head of 70m. It is lined with high wear-resisting rubber, whose abrasion resistance index is up to128%, the service life is 2-4 times longer than that of metal pump. XPAⅡhigh head wear-resisting rubber slurry pump is a rare rubber slurry pump with integrated effects of wear-resisting, anticorrosion and high head.
