Abstract

The invention provides an ore storage bin control system of a high-pressure roller mill closed circuit. The ore storage bin control system comprises a high-pressure roller milling unit and a screening unit, the high-pressure roller milling unit is used for carrying out high-pressure roller milling on input ore, and the screening unit is used for screening the input ore subjected to high-pressure roller milling; a roller milling buffer feeding control unit is arranged in front of the high-pressure roller milling unit, and a screening buffer control unit is arranged between the high-pressure roller milling unit and the screening unit; and the roller milling buffer feeding control unit is used for controlling the input quantity of input ore of the high-pressure roller milling unit, and the screening buffer control unit is used for controlling the input quantity of input ore of the screening unit. According to the ore storage bin control system of the high-pressure roller mill closed circuit, the problem that an existing ore storage bin control method is prone to causing operation conflicts, and then production accidents are caused can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of crushing system control of mineral processing plants, and more specifically relates to a closed-circuit mine bin control system for high-pressure roller mills. Background technique [0002] The high-pressure roller mill adopts the method of extrusion crushing. After crushing, the proportion of ore powder is large, and the iron ore has internal cracks, which can reduce the energy consumption of the next grinding operation to a certain extent; and the particle size of the high-pressure roller mill-screening closed circuit can reach If it is below 3mm-6mm, large particle size wet magnetic separation is carried out on it. In some mines, especially low-grade magnetite mines, the tail flick can reach 20%-30%, and the tail flick will not enter the subsequent grinding system, which greatly reduces the energy Consumption, equipment investment and production and operation costs. Based on this, many iron ore mines ...
