Over the last few years, with prospects high and demand booming, minerals processing plants and mining equipment grew in size and capacity.
Remote control and automation also became a favourable option for mining companies as they attempted to increase productivity.
Today, as the world reels from a recession that is slowly becoming more dominant, remote control is still proving to be a favourable option.
It allows miners to monitor equipment from a centralised control centre in turn, increasing the efficiency of the operation.
For the first time, one mining technology provider has developed a range of global mining screens that capitalise on the benefits of remote control and automation.
Metso has developed a range of screens that have imbedded SMART technology and adaptive abilities.
Global vice president of Metso Mining Screens Greg Albert told Australian Mining the screens were developed in response to the desperate need for screens that can compliment the same capacity and abilities as other equipment on site.
“In the nineties we were challenged by the market to develop larger capacity machines,” Albert said.
“This was then running concurrently with the introduction of larger capacity crushing, milling and conveying equipment.
“This resulted in the design of the then new multi angled screen decks which we pioneered.
“In the current era however, mining customers want a total solution which includes maintenance, plant optimisation and on site adjustability,” he said.
Metso built a mining screen range complete with adaptive technology
“For the first time, mining screens have the ability to adapt to the specific site conditions,” Albert said.
“The screens are infinitely adjustable and are global designs which means customers, with branches in many parts of the world, can implement the same technology on each minesite.
“We have put in place adjustable vibrator speeds, strokes, throws and angles. In fact, all of the main mechanical components are adjustable.”
With the new screen range, G Forces can be optimised and screen deck angles can be altered to optimise efficiency and media wear prior to installation.
Adaptor plates have also been installed on the screen support beam, which allows customers to adapt the deck surface to suit changing conditions or needs
Moreover, the screens are fitted with new linear motion gearboxes or the circular motion exciters with adjustable flywheels for stroke adjustment.
The screens can be driven with a vee belt, jack shaft and/or variable speed drive so that optimum speed can be achieved.
“Extensive trials carried out at our testing facility in Brazil, combined with crucial customer feedback have helped us challenge the traditional screen and exciter designs and replace it with an exciter that has the power to adapt to any environment,” Albert said.
