Application of HUATE®New Style Forced-oil Cooling Vertical Ring WHIMS in Beneficiation

Abstract

Promote and apply a new beneficiation technology and equipment effectively processing the refractory and medium-fine grained weak-magnetic minerals.

HUATE® Forced-oil Cooling Vertical Ring WHIMS adopts the transformer oil cooling technology to cool excitation coils, solving the easily generated scaling problem resulting from water cooling, thereby to eliminate the demineralized water system. With ＜25℃temperature raise, its magnetic field is stable. Wrapped by outer magnetic armor, it can generate a background intensity 1360kA/m. It effects very well in 1) wet preseparating the weak-magnetic coarse grains, like hematite, manganese ore, ilmenite, and purifying the concentrate; 2) removing the ferrous impurities and purifying the non-metallic minerals, like quartz, feldspar, kaolin; 3) enriching and recovering tailings from non-ferrous metals, like copper, lead, cobalt, molybdenum, thereby to greatly improve the mine resource utilization. It has applied 14 relative patents in China, and the invention patent in 56 countries, like Russia, USA, Australia, via PCT international organization. HUATE®WHIMS has been applied and accepted in more than 100 mines in and out of China.

Compared with water cooling vertical ring WHIMS, it’s energy-saving and water-saving, and avoiding generating the scale. While compared with JONES WHIMS under the same separation indexes, it’s featured of more space-effective, lighter, lower costs, higher gradient, higher efficiency, larger processing capacity and wider grain application scope. Greatly promoting development of mineral processing technologies, HUATE®WHIMS is the equipment to reduce costs and improve efficiency urgently needed by the mine enterprises now.
