Abstract

The invention relates to a vibrating device (1) that comprises: a supporting structure (2); a first rotating shaft (3) rotatably connected to the supporting structure (2) and having a first eccentric mass (4) secured thereto; and a second rotating shaft (5) rotatably connected to the supporting structure (2) and having a second eccentric mass (6) secured thereto, wherein the first (3) and second (5) shafts are concentric and rotate in opposite directions. The device is light in weight, has adjustable masses and can be coupled to other devices of the same type. Moreover, the device is characterized in that the supporting structure (2) comprises a base (7) and two independent lubricated cavities (8a, 8b) and a plurality of elongate elements (9) that connect the lubricated cavities (8a, 8b) to the base (7).

Description

technical field [0001] The present application relates to a vibrating device preferably used in screens for processing minerals. Background technique [0002] When used in mineral processing, sieves are vibrating machines that cause the acceleration of minerals through vibratory motion with a defined amplitude, for the purpose of stratifying (sorting or cleaning) or separating minerals from the fluid in which they are suspended (dewatering) . [0003] The vibratory force that excites the sieve (generated by the vibrating device) should remove as much mass inertia against the sieve as it does against the mineral (being processed), so if the sieve and mineral are of considerable mass, the force and energy required to move them will be larger. [0004] On the other hand, mining of increasingly lower mineral grades requires higher tonnages of minerals, which require large sized screens. [0005] This means that a single sieve (of larger size) requires multiple vibrating devic...
