GARTH TAYLOR, Mimico’s Crushing & Screening Business manager, says the operation at Matatoki has been set up in two parts.
“The initial unit consists of a Metso LT106 jaw crusher, a Metso LT200HP cone crusher and a Metso ST2.4 mobile screen, which are manufacturing the feedstock to then go to the mobile chip circuit.
“The mobile chip circuit consists of a Metso LT7150 Barmac VSI crusher, a Metso ST3.8 mobile screen, and a Metso ST4.8 mobile wash screen.
“That wash screen is also followed up with a Superior Industries 30” x 24’ fine material washer. This plant is making the various sealing chip grades for roading aggregate.”
Garth says flexibility was a key factor in the quarry choosing to go down this path.
“This allows HG Leach the ability to move plant to their various quarry sites and to also be able to manufacture sealing chip for other customers using their contract crushing capabilities.”
HG Leach & Co is still a family-focused company in an industry that is largely consolidating.
“I’m a fourth generation Leach,” says Ricky Leach, Plant & Maintenance manager.
“The company was formed back in 1952 by my great-grandfather, my grandfather and my great uncle.
“Today, we have four sites in the Thames Valley supplying aggregates locally and around the region.”
In addition to the operation at Matatoki, HG Leach also operates quarries at Tirohia, Tahuna and Waitawheta, expanding operations beyond the traditional family area of commerce.
This means the company is now no stranger to big jobs.
“Last summer we came off one of the biggest jobs in the whole 66 years of the company, supplying Rip Rap to the washed-out coast road north of Thames,” says Ricky.
“This involved north of 70,000 tonnes of product.”
HG Leach says it has a close relationship with Mimico, the distributor of Metso and Superior Industries’ equipment, parts and service support.
“We’ve had a very good relationship with them since 1996,” says Ricky. “We’re two family businesses working together with very similar family values.
“We can just jump on the phone …It could be the service manager, it could be the maintenance fitter, it could be the managing director.
“We get an answer straight away. We’re half an hour away from their [Matamata] site, which gives us very good service and also that relationship works very, very well.”
HG Leach & Co partnered with Mimico to supply its Matatoki Quarry, just south of Thames, with a fleet of mobile crushers to produce grades of sealing chip in what is now a completely mobile operation.
