A Detailed Look at Iron Ore Agglomeration - FEECO

And because iron ore varies from one sample to the next, so too does the process configuration. The FEECO Innovation Center is equipped to suit small batch tests on a single piece of equipment, as well as a continuous process loop to create the ideal iron ore agglomeration process. Items such as attrition, crush strength, compression, and bulk density are also measured through various stages of testing to,
