MIMICO, the New Zealand distributor of a range of world class quarry equipment brands, had a major presence at July’s annual QuarryNZ Conference in Hamilton.
By way of illustrating MIMICO’s ability to equip their customers’ success, the company displayed a range of equipment. This includeda Metso Lokotrack LT120 mobile jaw crusher, a Metso MX4 cone crusher, a Superior Aggredry® Dewatering Washer, a Kobelco SK500LC-9 excavator and a Kawasaki 95Z7 wheel loader.
New Zealand’s largest Metso mobile crusher purchased by Fulton Hogan
The Metso Lokotrack LT120, a 63-tonne mobile jaw crusher, was decked out in Fulton Hogan logos as it was scheduled to head to the company’s Tauhei quarry, just up the road in the Waikato, straight after the event.
In fact, MIMICO used QuarryNZ to officially hand over the LT120 to Fulton Hogan, who had Richard Fulton and Peter Walsh on hand for the ceremony. It is planned to be used in tandem with a Metso LT300HP (cone crusher) and a Metso ST4.8 (triple deck mobile screen) to produce aggregates for the Waikato Expressway.
The LT120 is a high-capacity jaw crusher, it is the largest Metso mobile crusher in the country. MIMICO’s Crushing and Screening Business Manager, Garth Taylor, said: “This machine is as big as you can economically move by road. A key advantage for Fulton Hogan with their LT120 is that blasted rock can be loaded by excavator directly into the hopper of the crusher, which helps reduce their processing costs.”
A reliable and efficient mobile crushing plant, such as the LT120, is the sum of several factors working smoothly together. “The Nordberg C120 jaw crusher with its large feed opening, of 1200 x 870 mm, provides excellent capacity even in the toughest applications,” explained Taylor. “The hydraulic drive ensures trouble-free operation and enables the crusher direction to be changed in case of blockage.”
Revolutionary new cone crusher technology available in New Zealand
Metso’s new MX is designed to redefine the way we think about cone crusher performance with claims previously unimagined around efficiency, wear part utilisation, safety and automation.
MX is the first ‘Multi-Action’ cone crusher on the market, combining the very high reduction ratios of the most demanding mining applications with superb end-product shape and consistency critical in aggregate applications.
Taylor explains further: "The MX is able to simultaneously adjust its setting with a rotating bowl above its cavity and a hydraulic piston inside the machine’s fixed shaft. Dynamic setting adjustments can be made when the crusher is operating under full load conditions without the need to stop production.
"Both rotating bowl and piston adjustments are fully automated, so no human intervention is required. The MX also provides a maximised tramp release distance, delivering high levels of protection against uncrushable objects and overloading. Protection is optimised under all conditions, even with completely new wear parts."
According to Taylor, the MX with its Multi-Action technology is the most cost-efficient crusher on the market. It enables operational cost savings of 10% or more compared with traditional cone crushers. Savings in wear components coupled with an effective and continuous crushing action, provide an unbeatable starting point to bring down the cost per ton in any quarry or mining application.
The new machine’s uptime is significantly better than traditional cone crushers. The MX’s Multi-Action design allows dynamic setting adjustment and wear composition with its hydraulic piston, minimising interruptions to production. It also provides rapid, fully automated protection via its rotating bowl. The combination of rotating bowl and piston adjustment enables optimised wear part utilisation.
One of the big advantages of the MX are its quick and easy wear component change-outs. All the wear parts are accessible from the top of the machine, allowing a complete change-out in just two to three hours.
Kobelco, Kawasaki, Superior complete the quarry offering
Large size Kobelco excavators and powerful Kawasaki Z7 wheel loaders are finding homes in quarries across the country. Both machines are comfortable, efficient and intelligent. The Kobelco SK500 provides big power for less fuel leading to unbeatable cost performance, while the Kawasaki 95Z7, with its large factory GSC 5.6 cubic metre bucket, delivers noticeable capacity gains.
Superior Industries’ Aggredry® Dewatering Washer is a combination of a fine material washer and a dewatering screen in a single machine. With sand specs becoming more precise, washing aggregate is more necessary than ever.
“Incorporating processes like washing and dewatering into job sites can create some common inconveniences,” said Superior Industries’ Jeff Steiner, who made the trip from the USA to be at QuarryNZ. “Processing wet material means there is often the need to find additional time for it to dry, which means delaying the reclamation of the stockpile. Also, extra space is needed for the drying product. The Aggredry Washer solves the problem by both washing and drying the material, producing instantly sellable material with a moisture content as low as 8%.”
The Superior brand was introduced to the New Zealand market in May this year, when MIMICO was appointed as the sole New Zealand distributor for the company’s washing systems and conveying equipment. “We’ve seen a lot of interest in this equipment already,” said Taylor.
