moisture content a stability problem in
The moisture of ore has a certain influence on the effect of dry magnetic separator, especially for fine-grained separating. Because moisture will increase the adhesion of the magnet group, make the magnet group more firmly bonded, and it is easy to stick to the barrel surface. moisture content and dry unit weight for saturated soil is shown on the graph in Figure 3. This line is known as the zero air voids line.
