Sandvik unveils new scalper, cone crusher and telematics system

It was a busy Hillhead for Sandvik Mining and Rock Technology last month, with the company debuting a new scalper, cone crusher and automation and control telematics system at the show.

The company used the Hillhead quarry as a backdrop to launch its QE342 screener/scalper, a “heavy duty [machine] … with class leading open scalping area enabling it to deliver enormous rates of production”, Sandvik said.

Built for the hardest wearing materials, the QE342 has a wear resistant steel apron feeder, large stockpiling capability, two-speed tracking and over-wide conveyors that maximise delivery.

It has a crusher-style chassis designed specifically to accommodate the engine power packs and comes equipped with a CAT C4.4 96 kW engine (EU Stage IV, Stage V and Tier 4 Final emission compliant options). The engine can operate at a speed of 1,800 rpm, providing lower fuel consumption and reduced noise compared with its predecessor, the QE341. The QE342 also comes with hybrid drive and electric plug in options.

“The QE342’s wear resistant rigid hopper is compatible for two-way or three-way split configurations, as well as having the ability to interchange side conveyors thereby demonstrating the ultimate flexibility of the unit,” Sandvik said.

The screen-box jack up facility allows easier access to the bottom deck for maintenance and screen media changes, while the hydraulic fluid change interval has been extended from 2,000 hours to 4,000 hours, providing a plus-50% saving as well as delivering environmental benefits.

An electrical control system has features to improve both the operational effectiveness and machine safety. This includes a key switch, mode selector switch (set-up, operation and tracking) and one global plant button to commence sequential automatic start-up and automatic shut-down of the plant while in operating mode.

“With a wide choice of screen media available, the QE342 can be configured to match specific requirements and is able to cope with a huge range of different, and difficult, materials and applications,” Sandvik said. “These include construction waste, landfill mining, quarry overburden, mine dumps, and scalping before a crusher or screening aggregates after a crusher.”

Two in one

The Sandvik stand also hosted a new mobile cone crusher at the show – the QH332 DDHS (pictured) – combining crushing and screening in one system.

“The brand new … QH332 DDHS (double deck hanging screen) is a tracked, self-contained cone crusher with an on board diesel engine. It is based on the world leading QH331, with this new cone crushing solution also providing the functionality of a double or single deck (utilising the top deck as a breaker deck) hanging screen in a fully detachable and standalone form,” Sandvik said.

“Able to be detached/attached without the use of additional lifting equipment, the QH332 DDHS thus delivers multi-functionality as a one-, two- or three-way split screener as well as a highly productive and efficient cone crusher.”

The machine is able to produce two screened products and recirculate the oversize back into the feed conveyor, which, itself, can be hydraulically rotated through 90o for stockpiling up to three products on the floor, according to Sandvik.

The CH430 cone crusher is at the heart of the QH332 DDHS and is equipped with a hydroset system that provides closed-side setting adjustment and a heavy duty I Beam chassis.

“The automatic setting regulation system not only optimises production, it also keeps track of liner wear, making it easy to plan liner changes and minimise interruptions in production,” Sandvik said.

The CH430 cone has a choice of six concaves and three eccentric bushes providing a range of throws from 16 mm to 36 mm.

As the standalone double deck hanging screen is completely detachable, operators can use the QH322 in open or closed circuit, with the machine able to be set up in less than 30 minutes, Sandvik said.

Going digital

Both of these new machines can benefit from the use of the My Fleet telematics system, which was also launched at the Hillhead show last month.

Developed initially for the premium (Q) range of crushers – expected in the September quarter – this digital solution has been designed to “help operators get the very best out of their investment”, Sandvik said. A launch for the company’s mobile screen and scalper range could occur soon after.

The monitoring, control and data collection tool, provided via the cloud, is designed to eliminate guesswork and provide the data needed for informed business decisions, according to Sandvik.

“My Fleet has been purpose developed to help our customers know exactly how equipment is being utilised. Through the collection and accurate monitoring of a wide array of parameters, this facilitates accurate production forecasting, ensuring that the most efficient use is obtained from equipment, thereby maximising return on investment,” the company said.

In addition to the ability to forecast production, this can also help customers plan their service and maintenance schedules.

There will be two packages available for My Fleet customers, with the option to take one of the packages or alternatively, opt out of the system. These consist of:

  • Freemium – a basic package aimed at providing machine location and utilisation
  • Premium – provides a wide array of parameters for a more in-depth analysis and monitoring of the equipment.
