GIW is now offering its new, patented hydrocyclone, featuring a breakthrough design that reduces rebuild time by 75%. The company says the “GIW Hydrocyclone dramatically reduces downtime, expense, and frustration through its unique, easy-maintenance design. Maintaining hydrocyclones in mining processes is a constant job, and every time one is taken out of commission for maintenance or rebuilding, precious production time is lost. Because hydrocyclones are such an important part of many mining and processing operations, GIW is now offering its own design as part of its mission to fully support customers’ pumping processes.”
GIW applies its extensive engineering expertise and quality service not just to its pumps, but to each customer’s entire slurry system. This commitment led GIW to look at how the hydrocyclone design could be improved to reduce maintenance downtime and overall system performance.
Most hydrocyclones are based on a basic design that has been used for more than 50 years. GIW decided to take a look at the needs of today’s mining and processing operations and offer a completely fresh design that makes installation and maintenance quick and straightforward.
The GIW Hydrocyclone is covered by 20 US and global patents. The design incorporates a straightforward tie-bolt and clamp assembly. A complete rebuild requires the removal of only seven fasteners. A twist-to-lock option simplifies apex removal and service, and drop-in, glue-free liners reduce build time. In addition, weep holes enable early wear detection, so customers can virtually eliminate unplanned outages.
The GIW design reduces a typical rebuild time from eight hours to two hours. This extraordinary improvement can result in hundreds of thousands of dollars in savings.
“We offer a lot of features that no one else can,” says Mark Davis, GIW Mill Products Manager. “An unplanned outage can cost anywhere from $50,000 to $150,000 per hour in terms of lost production, labour, and other overhead. We offer a longer wear life, and our cyclone takes a quarter of the time to rebuild compared with competitors’ cyclones.”
Even though the GIW Hydrocyclone is designed for easy maintenance, it also lives up to the GIW reputation for excellence in high-wear environments. Built in the US, the hydrocyclone includes long-lasting urethane and ceramic cones and powder-coated steel construction. These materials resist corrosion and damage from abrasion, acid, oil, hydrocarbon, phosphate, potash, and high temperatures.
GIW’s design also includes superior resistance to tramp and oversize materials by incorporating reaction bonded silicon carbide (RBSiC) and polyurethane components. This makes the GIW Hydrocyclone an optimal choice for primary ball mill, aggregate, tailings, regrind, coal-preparation, dewatering, and phosphate/potash processes.
The GIW Hydrocyclone is available in eight discharge sizes, ranging from 2.5 inches to 33 in. Repairs and rebuilds can be performed in place or on a build stand.
