The combination of Metso’s mobile wheeled NW106 primary jaw crushing plant and iNW220GPD secondary cone crushing plant with a large dual-slope screen has been optimised to be regularly relocated. Hydraulically fine-adjustable support legs, hopper walls and screen lifting allow for fast installation and dismantling. The plant has also been designed to be very easy and safe to operate and maintain on site.
"Setting up a conventional portable crushing and screening plant often requires preparations with foundations and other site conditions. The new Metso NW Series plant solution is designed to avoid all these challenges, and only minimal preparations on site are required," emphasised Eric Lavieville, global product manager, portable plant at, Metso.
A completely new plant conveyor design with fewer support legs makes setup quick and simple and no heavy cranes or concrete foundations are required. Service platforms on the conveyors make daily operations much easier and safer should the plant remain on site for a longer period of time.
According to the company, typical capacity of the NW Series with very hard feed material and four calibrated end products is 20% higher than that of any conventional solution now available in the same size class. This increased capacity is mainly achieved by the use of the powerful Nordberg GP220 cone crusher and the new dual-slope screen. The screen enables higher screening performance, and the whole process can be precisely adjusted by Metso's new IC50C process control system.
The new process control system is designed to form a seamless combination between the primary crushing stage and the secondary crushing & screening stage of the plant. The whole process can be started and stopped by the push of a single button, making daily operations easy and safe. It has been developed to meet customer expectations for consistent production, safety and easy control of the whole process. Feed and discharge conveyor control, wear compensation, auto setting adjustment and computer remote control are just a few of the many benefits the system offers.
