Power Supply Project for Mining Project in Guinea

PAUWAY supplied 4 units of PWM1375 diesel generator sets for a mining project in Guinea. As a star flagship product of PAUWAY, PWM1375 adopts the latest generation MTU engine with exclusive performance calibration and optimization by PAUWAY engineering team. This model is specially designed for continuous base-load operation, featuring prominent energy-saving performance and high comprehensive generating efficiency.

Project Background & Tender Award

Guinea boasts abundant bauxite mineral resources, and most open-pit mines are located in remote areas far away from municipal power grid coverage. Mining crushing lines, excavation equipment, drainage systems and mineral processing facilities require long-term uninterrupted stable power supply. The mine side puts forward strict requirements on unit continuous running capability, fuel economy and long-term operational reliability, and finally selects PAUWAY mature flagship PWM1375 model as the core power equipment for the project.

Core Technology & Equipment Configuration

Generating Units

The project is equipped with 4 sets of PAUWAY PWM1375 flagship generator sets. The power core is the latest technical version of MTU diesel engine. Combined with the actual working conditions of overseas mines, PAUWAY completes fine-tuning on fuel injection control, power output curve and heat dissipation matching. The four units can realize parallel group control and mutual backup, which can fully bear the long-term continuous power demand of the mining area as the main power source.

Project Positioning

Four-unit redundant main power station for open-pit mining area, providing all-weather continuous power guarantee for ore mining, crushing, conveying and on-site auxiliary production systems.

Equipment Features

• PAUWAY classic star product, mature and verified by a large number of overseas engineering projects
• Equipped with latest MTU engine assembly with advanced combustion and emission technology
• Exclusive overall performance calibration by PAUWAY to adapt to long-term base-load working mode
• Low specific fuel consumption, remarkable energy-saving effect, effectively reducing long-term operation cost of mines
• Four units support parallel operation, automatic load distribution and fault protection isolation
• Dust-proof and rain-proof structure upgraded to adapt to tropical high temperature and dusty open-pit mining environment in West Africa

Project Significance & Challenges

Project Value

The introduction of four sets of flagship PWM1375 units provides highly reliable main power support for Guinea bauxite mining development. The optimized fuel consumption performance greatly cuts the daily power operation expenditure of the mine, and further consolidates PAUWAY’s brand advantage in Africa large mineral resource development projects.

Execution Challenges

Complete factory full-load continuous operation test for each unit to verify calibration effect; finish sealed export packaging and international sea freight; carry out on-site multi-unit parallel debugging and access to mine central power distribution system; strengthen air intake filtration system to resist a large amount of mineral dust in open pit.
