Ball Mill or Rod Mill? This is a Question?

As we all know, the cost of grinding operations accounts for a considerable proportion of the cost of the entire mineral processing plant. Since the grinding investment is huge and the energy consumption is extremely high, it’s widely agreed that “Without a mill, there exist no mineral processing”, from which we can see through clearly the importance of grinding operation. Therefore, the dressing plants are also very cautious in the selection of grinding equipment , in order to yield twice the result with half the effort. At present, the most widely used grinding equipment in the dressing plant is ball mill and rod mill . As far as the working principle is concerned, both ball mills and rod mills are the same. The grinding medium (steel ball or steel rod) installed in the cylinder is lifted to a certain height with the rotation of the cylinder under the action of friction and centrifugal force, and then thrown at a specific line speed to impact, grind and squeeze the materials in the ...

Dry or Wet Magnetic Separator? How to Choose the Type of Magnetic Separator?

As a common beneficiation process, magnetic separation process separate minerals based on their magnetic difference, which widely used in the separation of black metals, non-ferrous metals and rare metal ores and the removal of iron impurities from other minerals, such as magnetite, titanomagnetite, hematite, limonite, siderite, ferrochrome ore and manganese ore, etc. While the common types of magnetic separation equipment can be classified into dry magnetic separator and wet magnetic separator depending on the material to be processed. The dry magnetic separator is the mainstream magnetic separation equipment and it was also used for industrial weak magnetic separation as the earliest magnetic separation equipment. It is suitable for dry and water-deficient areas and mainly used to select bulk, coarse-grained ferromagnetism and finer particles of weak magnetic ore, which has a simple Process flow. Common dry magnetic separation equipment includes dry weak magnetic separator (iron re...
