Increasing throughput while preserving product quality , minimising energy consumption and operating costs or increasing water recovery : efficient separation is a crucial competitive advantage in the mining and minerals business . Having mastered these challenges for more than a century , we at ANDRITZ know how to tailor our complete range of state-ofthe-art technologies to meet your needs and to find the best processing solutions . And , by exploring innovative new ways to automate and monitor remote facilities , we ensure that you are ready for the future as well .
Automating processes , cutting costs : one step ahead in digitalisation
Digital innovation is bringing a variety of benefits to industrial operations , and the mining and minerals sector is no exception . ANDRITZ has combined the power of smart sensors , big data analytics , and virtual and augmented reality to develop Metris , a portfolio of digital industrial solutions . Within this portfolio , Metris addIQ control systems offer cutting-edge machine and process control for solid / liquid separation equipment and systems . To ensure safe , trouble-free operations , ANDRITZ automation solutions range from upgrades to individual systems , including electrics , control equipment and instrumentation , to full automation of entire processes and plants . For greenfield plants , we design and test using dynamic simulations in order to ensure error-free startup . For upgrades and optimisation projects , we can customise a complete range of engineering , process simulation , control and training solutions depending on your individual requirements .
A wide range of equipment to tailor the right separation solution to your needs
ANDRITZ ’ s current portfolio covers the full solid / liquid separation process from sedimentation and dewatering to drying and ensures excellent throughput of high-quality products – all with low operating costs and maximum reliability . The variety of different thickening , dewatering and drying technologies , ranging from thickeners to decanter or pusher centrifuges , heavy-duty belt presses or hyperbaric disc filters to closedcycle contact dryers means that we are able to configure a processing line tailored to fit your specific needs . For the efficient and responsible treatment of coal tailings , for example , one line currently being installed in Australia consists of a custom thickener combined with belt presses ( whose efficiency is increased even further by the addition of Metris addIQ RheoScan ). Tailings treatment processes in two different sand washing plants are also using a similar setup ( with a gravity belt table between the thickening and dewatering step ), after pilot tests showed this tailings dewatering line to be the most efficient . But you can also choose between screen bowl decanters , disc filters and filter presses , the latter a flagship for the use of IIoT : The intelligent filter press . In essence , the chance to analyse your processing requirements , conduct tests in a state-of-the-art laboratory , and be offered an individualised line solution from a wide range of thickening and dewatering technologies – this is the strength of an experienced partner like ANDRITZ .
Efficient tailings treatment with automatic adjustment of polymer dosage
Tailings treatment continues to be one of the fastest growing challenges in the mining sector . At the same time , environmental risks , space constraints and water scarcity all need to be managed as cost-effectively as possible – after all , the result is a waste product rather than one that turns a profit . The two major cost factors are the polymer added to thicken the sludge and the operator hours required for this process . Innovative solutions like the Metris addIQ RheoScan , the first optical measurement system that detects sludge viscosity during thickening and dewatering processes , is just one example for more efficient tailings treatment . RheoScan can react instantaneously , adapting inline to the varying feed characteristics and setting the optimum polymer dosage rate . The system has proven itself in the environmental sector , in applications like municipal and industrial wastewater treatment , and can be adapted to other sludge conditions such as coal tailings . The first installations have consistently met the initial target of an average reduction of 20 % in flocculant consumption . What ’ s more , the efficient and accurate dosing of polymer has also significantly reduced overspills while increasing the efficiency of thickening and dewatering in the downstream machinery as well .
