Iron Ore Tailing Recovery Rotary Kiln

The iron ore and coal crushed and screened to respective sizes are fed to rotary kiln through feed tube in predetermined ratio The rotary kiln is slightly inclined at an angle 25 degree and rotated by AC variable speed motor at a variable speed ranging from 02 rpm revolutions per minute to 10 rpm

We are committed to building crushing, industrial grinding, ore processing and green building materials, and provides intelligent solutions and mature supporting products.
