Ball feeder control system based on DCS system platform

Abstract

The invention discloses a ball feeder control system based on a DCS platform, belongs to an ore dressing automatic control technology, and particularly relates to an automatic steel ball feeding system of a ball mill. The system comprises a steel ball counting and outputting device and a DCS detection control system. According to the system, a timing period new ore feeding amount automatic calculation unit, a steel ball demand quantity automatic calculation unit, an actual steel ball adding automatic control unit and an automatic period circulation control unit are arranged, the number of thesteel balls needing to be added is calculated, a command is sent out to enable the steel ball output device to add the steel balls into the ball mill, the adding amount is metered, and is fed back tothe actual steel ball adding automatic control unit, and the next adding period is entered after adding is completed. According to the invention, the labor cost is reduced, the safety production indexis improved, the direct production cost is reduced, the system operation difficulty and maintenance difficulty of operators and automation technicians are reduced, and the high efficiency of the steel ball adding system is improved.

Description

technical field [0001] The invention belongs to the mineral processing automatic control technology, in particular to a ball mill steel ball automatic adding system. Background technique [0002] At present, there are two main ways to add steel balls to the mill system of copper mines with a daily processing capacity of more than 10,000 tons in China: 1 is to use an aircraft to hoist the steel balls to the mine inlet of the mill, and add the balls manually; 2 is The specially designed mill steel ball adding control system is adopted, with PLC as the core, supporting instruments and electrical equipment together to realize the automatic adding of steel balls. [0003] The way of manually adding steel balls requires a lot of manual handling, which increases the physical workload of employees and reduces the physical and mental health index of employees. In addition, in the process of hoisting steel balls, there are large safety risks such as aerial crane operations, cross ope...

AI Technical Summary

Problems solved by technology

In addition, in the process of hoisting steel balls, there are large safety risks such as aerial crane operations, cross operations, and high-altitude operations.

To add a complete set of steel ball adding control system with PLC as the core, the design of each ball adding machine control system, equipment spare parts materials, installation, commissioning, etc. are too much investment, which is difficult to afford.
