Ore cleaning system

The utility model discloses an ore cleaning system, which comprises a globe mill, a grader, a plastic pump, a swirler and a concentrator which are sequentially connected through pipelines, wherein the backflow ends of both the grader and the swirler are respectively connected with a feeding port of the globe mill through a pipeline, an overflow port of the concentrator is connected with a water storage tank, the water outlet of the water storage tank is connected with a main pipeline, the main pipeline is connected with a discharging pipe of the globe mill and/or a backflow pipe of the grader, and the main pipeline is provided with a pipeline pump. By adopting the above structure, water which is overflowed from the concentrator is firstly stored into the water storage tank, and the pipeline pump pumps the overflowed water which comprises rich calcium oxide to the globe mill and the grader to be used. The recycling of the overflowed water saves the calcium oxide for the production, reduces the burden of the se
