The state-of-the-art mine hoist system will help Kryvyi Rih (Krivoj Rog) iron ore plant?s Zarya Mine increase productivity while lowering energy consumption.
ABB, the leading power and automation technology group, has won an order to supply a mine hoist system to Zarya Mine, Kryvyi Rih iron ore plant (Kryvbaszalizrudkom JSC) in Ukraine. Being one of the mine's key elements, the hoist will lift the ore from 1,717 meters depth with 50 ton skips at a speed of 12 m/s.
The recent order consists of the complete mine hoist system with the mechanical part equipped with hydraulic disc brakes, two 3,700 MW overhung synchronous motors and an ACS6000 MV drive inverter, power transformers, medium and low voltage switch gears, a state-of-the-art control and monitoring System 800xA incorporating underground control equipment, shaft alarm, as well as an operator control panel and a combined operator and engineering station.
"This project is very promising not only in terms of development of our company's business but also for the whole Ukrainian mining industry," said Igor Khilko, manager of ABB's Process Automation division in Ukraine. "Mine operators are now in urgent need of production upgrade. The use of ABB products and solutions will thus not only allow to replace obsolete equipment but also to significantly improve energy efficiency, productivity and reliability of operation."
A complete ABB mine hoist system including mechanical, electric drive and control equipment has been in operation at Zarya Mine since 1960 without any modifications. Due to the system's proven reliability and the long-term service provided by ABB, the customer now decided to order new ABB equipment.
The hoist system replacement with the newest equipment from ABB will enable Kryvyi Rih iron ore plant to increase productivity, reduce maintenance time and cost, cut energy consumption as well as improve energy efficiency.
ABB in Sweden is the main contractor for this project providing manufacturing and supply of the equipment. Parts of the project will be executed by local engineering and service centers of ABB in Ukraine as well as Ukrainian partners of the company.
