New Generation of Scrap Shears from Metso Lindemann - Trailblazers in Scrap Shears Yet Again

(Web Magazine 2002)

Metso Lindemann obviously knows the needs of the market. During the recent past, this Dusseldorf-based company - part Metso Minerals, a member of Metso Corporation - has notched up noteworthy successes in the worldwide shredder and press market with its Power Zerdirators and RAS scrap baling presses. The company Metso Lindemann is now confident that its latest innovation in scrap shears will prove yet another market hit.

"We know that our customers around the world are increasingly looking for products that will enhance their competitive position. Consequently, our aim was to develop a series of scrap shears whose efficiency - in terms of flexibility, energy consumption, operating reliability and ease of maintenance - would surpass that of existing shears," explains August van der Beek, head of Metso Lindemann’s Recycling Equipment Division.

And the result is impressive indeed. It prompted Metso Lindemann to give the new generation of shears the indicative name of -Cut (pronounced Eta-Cut) - incorporating the Greek letter (eta), the technical symbol for efficiency.



The key innovative features of the Lindemann EC series, which enable operators to process scrap more flexibly and profitably, comprise

• An optimized drive and control system, which reduces cycle times by a further up to 15% with no increase in driving capacity, although all effective compression forces have been increased;
  
• Different operating programs for processing the widest possible range of scrap types efficiently. In fact, the shears can automatically identify the most effective mode of operation for a particular material;
  
• An integrated infinitely variable positioning system for precisely controlling and monitoring piston strokes, speed and acceleration. Unlike the proximity and limit switches conventionally used, this system is insensitive to dirt and falling scrap;
  
• Possibility of steering precisely towards the optimum hydraulic switch positions to increase the cutting rate and avoid hydraulic shocks;
  
• Assured capacity for compacting bulky shredder feedstock into logs by virtue of the increased pressure forces;
  
• WearCon automatic wear monitoring system, which automatically signals in good time the impending need for a change of wear plates;
  
• Hydraulic blade tensioning device, which guarantees monitoring of the correct setting and tension of the blades and automatic readjustment, if necessary;
  
• Computer-controlled central lubrication of all guides;
  
• Comprehensive wear protection, plus even simpler exchange of wear parts with no need to remove entire functional units;
  
• Reduced filling height, permitting a better view and faster loading;
  
• Integrated feeding hopper, which, even during the cutting process, can take in sufficient quantities of material for the next operating cycle, and thus ncreases effective production time;
  
• Integrated mobile scrap chute, which ensures trouble-free output removal with less noise;
  
• Modular design of the press beds, which forms the basis for a no-delay supply of wear plates;
  
• Dynamic oil level control, which detects even the slightest losses of oil and provides increased protection for the hydraulic assemblies and the environment;
  
• Visualization of process data, with a clear-text user interface and data display, also on decentralized computers;
  
• Remote diagnosis via Teleservice, facilitating quick, economical support.
