Iron ore grinding process,process design for

There is no strict restriction on the upper limit and particle size distribution of the products in the open-circuit grinding process. Because the ore to be ground passes through the grinding machine only once, the product size is relatively coarse. This type of process is commonly used in the first stage of the single-stage rod milling process or the first stage of the two-stage grinding

Study of Iron Ore Mixtures Behavior in the

Grinding, the first operation in the process, is a crucial step for the subsequent operations. Three iron ore mixtures with different grindability index (low, medium, and high) were used in order to verify the influence in the operational parameters such as production rate, discharge density, and pump pressure.
