A bypass metal removal device

Abstract

The invention discloses a by-pass metal removing device. The by-pass metal removing device comprises a first metal detector, a control cabinet, a driving mechanism, a metal removing mechanism, a metal discharging part and a second metal detector; the first metal detector is used for detecting metal impurities on a conveying track and sends first alarm signals; the control cabinet receives the first alarm signals and sends first control commands to the driving mechanism; the driving mechanism drives the metal removing mechanism to move according to the first control commands, so that a conveying path of the metal removing mechanism is separated from the conveying track, and the metal impurities are conveyed along the conveying path of the metal removing mechanism and fall into the metal discharging part; the second metal detector is used for detecting the metal impurities falling into the metal discharging part and sends second alarm signals; the control cabinet receives the second alarm signals and sends second control commands to the driving mechanism; and the driving mechanism drives the metal removing mechanism to move according to the second control commands, so that the conveying path of the metal removing mechanism overlaps with the conveying track.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a bypass metal removal device. Background technique [0002] In the beneficiation plant, it is necessary to use medium and fine crushing equipment to carry out medium or fine crushing operations on the mined solid materials, but in the process of handling and transporting solid materials before crushing, some iron nuggets, iron brazing, iron rods, etc. are often mixed in Iron impurities and some other metal impurities, these metal impurities are difficult to crush, and will cause great harm to the medium and fine crushing equipment. For example, if these metal impurities enter the standard cone crusher or short head cone crusher, they will destroy the crushing cavity If these metal impurities enter the high-pressure roller mill equipment, they will damage the roller surface and teeth, and even get stuck between the two rollers. cause the equipment to stop running. ...
