Description

Technical Field

[0001] The invention relates to the technical field of ore dressing devices, and in particular to a rotary ore dressing device. Background Art

[0002] In the process of development and utilization of mineral resources, mineral processing is a crucial link. Mineral processing is to separate useful minerals from gangue minerals by gravity separation, flotation, magnetic separation, electrostatic separation and other methods after crushing and grinding the ore according to the physical and chemical properties of different minerals in the ore, and to separate various symbiotic (associated) useful minerals from each other as much as possible, remove or reduce harmful impurities, so as to obtain the raw materials required for smelting or other industries. With the continuous advancement of science and technology, higher requirements are put forward for the efficiency, accuracy and reliability of mineral processing equipment. As an important mineral processing equipment, rotary mineral processing equipment plays an important role in the mining field.

[0003] Before the emergence of rotary beneficiation devices, traditional beneficiation methods mainly include gravity beneficiation, flotation, magnetic separation, etc., but they have certain limitations. In order to overcome the limitations of traditional beneficiation methods and improve beneficiation efficiency and accuracy, rotary beneficiation devices came into being. Its working principle is usually that the ore is fed into the rotary device. During the rotation process, due to the differences in the physical properties of different minerals (such as density, particle size, shape, magnetism, etc.), and the effects of centrifugal force, friction, gravity and other forces, the minerals will move in different positions and directions, thereby achieving the separation of useful minerals and gangue minerals. Rotary beneficiation devices are widely used in mining, metallurgy, chemical industry and other industries for sorting and purifying various metal ores, non-metallic ores, etc. For example, in iron ore beneficiation, a rotary magnetic separator can be used to separate magnetic iron minerals; in gold ore beneficiation, a rotary gravity separation device can be used to enrich gold ore, etc.

[0004] The existing mineral processing equipment has a low transmission effect, which leads to a decrease in the ore selection efficiency, resulting in loss and wear of the mineral processing equipment, and further affecting the overall working efficiency of the equipment. For this reason, we propose a rotary mineral processing equipment. Summary of the invention
