Iron ore selectingmachine, extract iron sand from pumped material, magnetic seperation, recovery rate 90%, diesel engine driven - details see: https://www.machineto.com/iron-ore-selecting-machine-diesel-engine-driven-mineral-processing-machine-10311756

Iron ore selecting machine diesel engine driven mineral processing machine

Working mode:
pump sand from water

- separate stone through simple sieve
- enter the water tank

- materials flow steady into the magnetic roller through the slide board

- iron extraction
- iron sand being discharged to shore by sand pump which is driven by diesel engine

- wastes being dumped through chute
