The 750 gauss Interpole magnetic element, developed by Eriez, is the most acclaimed magnet of engineering standards in the industry. Eriez has also set the benchmark for wet drum performance. The culmination of various in–plant tests has demonstrated that the separators will achieve magnetite recoveries in the 99.9+ percent.
Wet Drum Magnetic Separator Components ... (10 ft) in drum width. Historically two different basic tank styles have been employed in heavy media applications—concurrent and counter-rotation. These tank styles are illustrated in Figure 4. With the concurrent tank style, the drum rotates in the same direction as the slurry flow. ...
The Jones wet high-intensity magnetic separator (WHIMS) was developed in 1956.The structure of the Jones separator is shown in Figure 9.6 and consists mainly of an iron-core electromagnet, a vertical shaft with two (or more) separating rings, a driving system, and feeding and product collection devices. Grooved plates made of magnetic conductive …
