CRUSHING AND CONVEYING * STOCKPILES

Under these conditions, coarser ore tends to roll farther down one side of the stockpile than the other, and the fine ore tends to fall under the feed conveyor discharge point. Consequently, the stockpile tends to classify, or separate, the crushed ore based on size. The ore at the center of the stockpile tends to be finer than the ore at the ...

The Role of Slurry Pumps in Mining Operations

 — This is often done with slurries - mixtures of crushed rock or mineral ore and water. Slurry pumps are used to move these dense mixtures through pipelines efficiently over long distances. The slurries can contain large particles, up to several inches in size, and have high solids concentrations up to 80% by weight. ... high-volume pumping vital ...

Grinding-Classification Circuit

 — The crushed ore is ground to the product particle size required by the subsequent production process. It is mainly applicable to the treatment of ore with uniform and fine embedded particle size. For example, the concentrator adopts the continuous grinding-classification circuit of one-stage rod mill, two-stage ball mill, and three-stage …
