Tailing sand is the product of magnetic separation of iron ore processed by ball mill. Its particle size is relatively uniform and contains some iron components. Tailings sand is generally discharged as waste, it will not only pollute the environment, but also a waste of resources in this way. After the tailings sand is treated by the sand washing machine, clean construction sand can be obtained. So what kind of sand washer is better for tailings? This paper focuses on the introduction of spiral sand washing machine for tailing sand treatment.
In order to select a good sand washing machine to deal with tailings, the following aspects should be analyzed:
1.Impurity content of tailings sand
If the impurity content of tailing sand is not very high, the wheel bucket type sand washing machine can be selected when the sand is relatively clean. If not, the screw type sand washing machine is recommended.
2.Fineness of tailings sand
If the fineness of tailing sand is relatively fine, it is suggested to select the wheel bucket type sand washing machine,Otherwise, the screw type sand washing machine can be selected to reduce the loss rate of fine sand.
3.Output of tailings sand
If the output requirement of tailings sand is relatively high, the screw type sand washing machine can be selected. Or else, the wheel bucket type sand washing machine can be selected.
