Ore dressing production automatic control system

Abstract

The invention discloses an ore dressing production automatic control system, which comprises an operator station 5 of a control system, an Ethernet bridge 1, a system controller 2, an in-site detection switch 3, a motor 4 and a crushing and conveying device, wherein slide switches 9 are arranged on driven rolls of belt conveyers arranged in the crushing and conveying device, i.e. the slide switches 9 are arranged on the driven rolls of the belt conveyers 14 and 15 of the crushing and conveying device of the crude crushing work section; a slide switch 9 is arranged on the driven roll of the belt conveyer 24 of the crushing and conveying device of the fine crushing work section; and the control system is a DCS or PLC system. The DCS or PLC system of the invention can be used for judging whether the speed of the belt conveyers is in a normal state or in a speed lack state through detecting the states of the slide switches 9 arranged on the driven rolls of the belt conveyers of the crude crushing work section and the fine crushing work section, so the belt conveyers can be started or stopped for automatically increasing or decreasing the material amount. Thereby, the invention realizes the automatic control of the material feeding and material reducing of ores without manual regulation.

Description

Mineral dressing production automation control system technical field The invention relates to the technical field of iron ore beneficiation production, in particular to an automatic production flow control system of an iron ore beneficiation plant. Background technique With the development of my country's iron and steel industry and the restriction of the price monopoly of international ore giants, my country's iron ore resources urgently need to tap the potential and expand production. At present, the beneficiation equipment of various small and medium iron ore mines in my country is outdated, basically in the stage of manual manual control, and the production efficiency is low. Especially in the coarse and medium crushing section of belt conveying, the belt load changes greatly, and the belt is easy to slip, so the feeding and reducing of ore must be controlled manually. At the same time, the deviation of the belt is also very serious, and frequent manual adjustments a...
