We have a solid track record of adding value to our clients’ businesses through the delivery of sustaining projects and providing a range of site services. Our experience covers the project lifecycle from initial opportunity screening through to final handover to site operations.
Our involvement often starts by working jointly with site operations on problem identification, root cause analysis, providing recommended options and preliminary estimates of total installed cost and schedule. Our focus is on reliability improvement and production enhancement.
Following project sanction we can complete engineering only or, if required, full EPCM services up to and including final acceptance and project close-out support. Alternatively we can offer Design & Construct services through our well established relationships with construction contractors.
Transfer Chutes
A large number of our sustaining projects involve rectification of problematic transfer chutes with issues including excessive liner wear, belt tracking / wear, chute blockage / spillage and restricted operational access. Following site audits, and in close collaboration with key site stakeholders, we determine root causes and develop practical solutions which are drawn from our experience of solving similar issues.
Discrete Element Modelling (DEM) techniques may be undertaken to assist in benchmarking the issue and develop pragmatic solutions. Onyx has experience with various industry wear liners and their relative advantages and limitations: we provide our clients unbiased, independent advice on optimum liner selection.
We have successfully reduced downtime, improved reliability and capacity on transfer chutes with products ranging from primary crushed ore through to highly cohesive and adhesive fines and tails materials. Our experience covers the entire process plant transfer systems from ROM bin through to rail loading and ship loading.
