iron ore primary grinding

Cast Grinding Steel Balls

This is particularly true for some of the secondary grinding (primary ball mills) of magnetic iron ores. In magnetic iron ore grinding, the silica levels are continually being decreased from crushing to rod milling to ball milling by intermediate concentration steps. Subsequently, the wear environment becomes progressively less abrasive.

What is the purpose of crushing, grinding and milling

Answer: The purpose is to break the valuable mineral grains free of the gangue minerals, so that they can be physically separated from each other. This makes it possible to produce a pure mineral concentrate using processes like froth flotation or magnetic separation. So if an ore consists of gra

Beneficiation Plants and Pelletizing Plants for Utilizing

Grinding is a sub-process of finely grinding ore in advance, such that the ground output can be physically separated into iron ore and impurities in the downstream sub-process. In many cases, an autogenous mill (AG mill) or a semi-autogenous mill (SAG mill) is used for the primary grinding, and a ball mill is used as the secondary for further
