Magnetic Ore Iron Reduction Process In Tunnel Kiln India

Tunnel Kiln history dates back to 1807 when Hoganas first used this process to produce iron powder of 99.9 purity. When iron ore is mined or processed in a crusher, lots of fines are generated. Quantity of fines generation is a function of the quality of ore i.e. whether it is hard or soft.
As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.
