Precision Screen

 
 
  S-4 Double Screen  
 

Features:

  • The machine is powered by diesel hydraulics and is self-propelled on tracks. It has high ground clearance and generous approach angles.
  • Low height allows transport by “Step Frame” trailer.
  • Patented double screen box arrangement gives highest screening capacity in its class. Independent adjustment of primary and secondary screen boxes minimises mesh wear and improves throughput and product separation.
  • Single mesh primary screen box minimises cost of mesh replacement in the impact area.
  • Separate hydraulic adjustment of the screening angle of each screen box giving over twenty different combinations of screening angle.
  • Three large capacity stockpiling conveyors are fully integrated into the machine.
  • Rapid ratcheting tensioners allow fast mesh changes.
  • High efficiency hydraulic system utilises Piston type motors to maximise power.
  • Hopper fitted with variable speed belt feeder.
  • “Centrefold” Main conveyor maintains correct belt tension in all positions.
  • Low main conveyor angle begins at 21.5° to permit movement of free-flowing material. Heavy-duty motor allows slow running with heavy load.
  • Hydraulic main conveyor head lift allows easy access for mesh change.
  • New main conveyor spreader plate allows full use of screen mesh width.
  • Optional vibrating grid enables the most difficult, heavy material to be processed.
  • Direct drive vibrating grid and screen boxes give enhanced efficiency with minimum maintenance - no V-Belts.
  • Hydraulic walkways deploy in seconds, giving low access height and safe working area for maintenance and mesh change.
  • Remote control of tracking and grid tip functions.
  • Effective sealing minimises spillage and dust generation.
  • Steel pipe runs used in hydraulic system give improved temperature control and extended hose life.
  • High capacity fuel tank allows increased run-time between refuelling.
  • Low side conveyor transport position allows easy access for maintenance.
  • Improved access for regular maintenance.
  • SKF – Sealed for life bearings.
