Powerscreen impact crushers are designed to excel as primary impactors, taking large feed material and reducing it down to a sellable product.

Powerscreen's impactor range is ideal for shaping applications including making chips, sand, concrete manufacture, and glass recycling. The range includes both horizontal and vertical impact crushers.

Impactors are often used as a cost-effective alternative to jaw and cone combination plants as they have a good level of reduction and product shaping for many applications.

Bathurst Resources recently took delivery of a new Hyundai HL970 wheel loader at its Takitimu operation in Southland. Serviced and supported by Porter Equipment, this latest addition to the fleet builds on the reliability the mine staff expect with new tech and tough engineering.

The ‘rule of three’ is a crucial part of operations at Bathurst Resources’ Takitimu sub-bituminous coal mine. Well, the rule certainly applies to the company’s wheel loader fleet, which always numbers two frontline machines and a reserve.

The key considerations for operators working in the fast-paced, ever-changing, always-evolving, contracting environment are:

Availability Reliability Productivity

Metso's Nordtrack I908S is ideal for short-term contracts and new crushing operations. It is robust and excels in asphalt recycling, concrete demolition, and rock crushing.

“The Nordtrack I908S provides a powerful and versatile impact crusher and screen plant in an easily transportable 27.5-ton package,” explains Garth Taylor, crushing and screening business manager at MIMICO, Metso’s New Zealand distributor.

At OceanaGold in Waihi, the art of extracting gold from rock is a long and intensive process requiring many big machines and skilled workers. Recently, a Sandvik mobile jaw crusher joined the fleet to facilitate the magic.

Gold was first discovered in Waihi in 1878 on Pukewa (Martha Hill), and miners, using explosives, picks, and shovels, loaded quartz rock onto wagons on rails in the tunnels, before it was lifted to the surface and sent to be crushed then treated to extract the gold and silver at the Victoria Battery.

Understanding what you are crushing and screening is crucial to optimising the performance of a processing plant. It will allow you to achieve the desired end-product, and operate a plant that is both cost effective and maximises availability and up time.

What matters

The physical properties of the material are key, and there are several factors that will affect the performance of a crusher.

Crushability, abrasiveness, geology (graywacke, basalt, granite), density, moisture, size fraction, and material contamination are, in our opinion, crucial factors to consider.

Stevens Group had a successful networking aggregate and quarrying event at this year’s Quarry NZ conference, which was held in early July 2023.

It was the biggest year for attendance yet, with 704 delegates and exhibitors coming together at the Te Pae Convention Centre in Christchurch.

“The annual event is where the Aggregate & Quarry Association (AQA) and the Institute of Quarrying (IOQ) do a tremendous job in facilitating interaction, socialising, and the sharing of experiences for all those involved in the quarrying industry,” says Stevens Group marketing manager Catrina Quinn.

This year marks Stevens Group's 50th anniversary.
