Embodiment Construction

[0011] The present invention replaces the faulty equipment with twisted cages to realize the continuous production method of iron ore grinding and separation. If any equipment of ball mill, magnetic separator and classifier in the iron ore grinding and separation production line fails, the upstream and downstream equipment of the faulty equipment are connected through twisted cages. , to maintain the continuous production of the iron ore grinding and dressing production line. The twisted cage includes a conveying trough, and a conveying screw is arranged along the length of the conveying trough in the conveying trough, and the conveying screw is driven by a motor, and the twisted cage is movable. Replace the faulty equipment by twisting the cage to continue production, and at the same time repair the faulty equipment to avoid the impact of the faulty equipment on the production rhythm, improve the operating rate of the equipment, and maintain the continuous production of the en...

Abstract

The invention discloses a method for realizing iron ore grinding and separation continuous production through twist cage replacement failure equipment and relates to the technical field of ore dressing process control. The problem that the whole production line needs to halt due to overhauling of faults of any equipment of existing iron ore grinding and separation production lines and then continuous production is influenced is solved. According to the technical scheme of the invention, if any equipment of a ball mill, a magnet separator and a grader in an iron ore grinding and separation production line breaks down, upstream and downstream equipment of failed equipment are connected through twist cages so as to maintain continuous production of the iron ore grinding and separation production line. The production continues through the twist cage replacement failure equipment, and the failure equipment is repaired. Thus, the failure equipment is prevented from influencing the rhythm ofproduction, and continuous production of the whole production line is maintained. The method is a forceful guarantee for the overall operation of the production line. By regulating the rhythm of production and through the mode of slightly reducing production for organizing production, the method can meet requirements of product quality.

Description

technical field [0001] The invention relates to the technical field of beneficiation process control, in particular to a method for temporarily replacing faulty equipment with twisted cages in iron powder production, thereby realizing continuous production of iron ore grinding and beneficiation. Background technique [0002] The iron powder production process adopts ball mills, magnetic separators, and classifiers to gradually grind and classify iron-containing materials, so as to increase the content of metallic iron to meet the requirements of iron powder products. There is a failure rate in the use of ball mills, magnetic separators, and classifiers. The longer the equipment is used, the higher the failure rate. The online repair time of magnetic separator and classifier is relatively short, and can be repaired in half a day, which has little impact on iron ore grinding and dressing production. However, ball mill maintenance takes a long time. It takes about five days to...
