Embodiment Construction

[0054] The present invention describes a method for a rotary dumper 1 (see figure 2 ) system and method of controlling the cycle time in a closed grid using information about the level of the bins 7 and information about the positioning of the cars 2 such as current, torque, speed and position.

[0055] The ideal cycle time is calculated using the level of the bin 7 such that when the bin 7 is full the cycle time only keeps the bin 7 full and when it is low the cycle time is reduced depending on the force measured on the positioning bin 2 to maximum limit.

[0056] The control system always calculates the ideal cycle time based on the information of the communication control of the carousel dumper 1 , allowing to increase or decrease according to the level of the cabin 7 and the request status of the positioning box 2 .

[0057] Therefore, the control system requires additional force to position the car 2 only when it is really needed. Information about the current, torque,...

Abstract

The invention relates to a control system and a control method for a rotary car dumpers. The control system for the rotary car dumpers 1 comprises a positioning car 2, silos 7 and feeders 8. Such control system comprises three integrated and communicating controls in closed grid, that is, the positioning car control 2, the silos level control 7 and the feeder flow control 8. In this way, with thedata of these controls, the rotary car dumpers 1 control system is configured to maintain the level of silo 7 at maximum, performing changes in the cycle time by controlling the positioning car 2 to maintain the level of silos 7 and thus achieve maximum productivity of the equipment.

Description

technical field [0001] The invention relates to an operating system and a method for performing monitoring and control of a rotary dumper in the mining field. Background technique [0002] With increasing demand for iron ore and increasing competitiveness in world markets, the search for better efficiency in port activities is fundamental to ensuring the economic sustainability of the company. [0003] The iron ore business chain usually and basically consists of three units: mines, railways and ports. All assets that make up this chain of operations are designed to allow handling of the high volumes of material expected from the system. If an asset does not work within the desired productivity value, it becomes an impediment (bottleneck) to the entire system. [0004] Rotary dumpers are important assets and form the port portion of the iron ore business chain triad. The process performed by the rotary dumper is designed to receive train cars from mines and dump ore into ...
