Leader in centrifugal systems
SOLID bowl centrifuges have emerged as an energy and water efficient technology that can more than match the capacity of belt filter presses for tailings dewatering.
As a leading provider of tailings dewatering technologies, and a presence in Australia for more than 90 years, Alfa Laval provides solid bowl centrifuges to mining companies around Australia and the world.
The company is a world leader in solid-liquid separation, heat transfer and fluid handling.
Its designs focus on enhanced energy efficiency, improved heat recovery, responsible use of natural resources, better water treatment and reduced emissions.
It has committed hefty research and development investment to designing and manufacturing solid bowl centrifugal systems with very large capacity, up to 80 dry tonnes per hour, specifically designed for heavy duties in mining and mineral processing.
In Australia, it has a particular focus on coal, copper, iron ore, gold, nickel and uranium tailings.
Dry tailings can be disposed of alongside coarse rejects using a similar process to overburden.
Alfa Laval dry disposal alleviates the risky and expensive practice of maintaining a tailings dam, which results in the discharge of significant quantities of toxic tailings into the natural environment if it fails.
Mining companies can also gain additional capacity with solid bowl centrifuge as existing Tailing Storage Facilities (TSF) are reaching capacity and new licenses are harder to come by.
Further advantages of Alfa Laval’s efficient solid bowl centrifuges is a reduction of water usage by up to 90pc, as process water can be extracted and re-used.
It will soon be introducing a full-scale skid mounted modular unit for onsite trials and interim solutions for tailings dry disposal.
Alfa Laval’s innovative technologies are dedicated to purifying, refining and recycling material.
In the case of fine coal recovery, next generation solid bowl centrifuges open up significant new revenue streams for customers to extract smaller particles from slurries than ever before.
Working with customers throughout the entire process, the company draws upon its strong R& D commitment as well as its significant inhouse engineering expertise.
It provides commissioning, training, onsite field services, trouble-shooting, process optimisation and major overhauls of centrifuges.
The end-to-end service doesn’t stop at installation.
Over its nearly 100 years working with Australian mining companies, Alfa Laval has developed a strong local support presence, including a fully equipped service centre in Sydney, and field engineers based around Australia to visit even the most remote mining sites.
It also specialises in heating, cooling, waste heat recovery, evaporation, condensation, desalination and zero liquid discharge as well as fine coal recovery and tailings dewatering.
Alfa Laval has a presence in more than 100 countries, 17,000 employees and holds more than 3500 patents worldwide.
