AI Technical Summary

Technical Problem

In the existing technology, the design load of the belt conveyor in the laterite nickel ore washing line cannot be effectively controlled, resulting in the belt conveyor often being underloaded or overloaded, increasing the risk of equipment damage.

Method used

The current signal acquisition module is used to obtain the belt conveyor motor current value, determine its threshold range, and adjust the feeding speed of the feeder according to the corresponding relationship between the motor current threshold range and the feeding speed to achieve adaptive control.

Benefits of technology

The belt conveyor load is evenly distributed, avoiding the situation where the belt conveyor load is too high or too low, improving equipment utilization efficiency and reducing the risk of belt tearing.

Abstract

The invention discloses a uniform discharging control system and method for a laterite-nickel ore washing line, the uniform discharging control system for the laterite-nickel ore washing line comprises a current signal acquisition module, a judgment module and a feeding speed control module, the current signal acquisition module is used for being connected with a motor of a belt conveyor to obtain a motor current value of the belt conveyor; the judgment module is used for judging a threshold interval in which a motor current value of the belt conveyor is located; the feeding speed control module is used for adjusting the current feeding speeds of the multiple feeders according to the corresponding relation between the motor current threshold value interval and the feeding speeds; the self-adaptive control over the feeding speed can be achieved, so that the discharging weight difference of gravels generated by ore washing is reduced, the situation that the design load of a belt conveyor is low or high can be avoided, efficient utilization of equipment is facilitated, and meanwhile the risk that a belt of the belt conveyor is torn can be reduced.
