Designed to be the most productive, reliable and efficient primary gyratory crusher on the market

Features

Designed for low service requirements and ease of operation, the SUPERIOR primary gyratory will readily fit into any existing or proposed crushing plant.

  • Rigid one-piece steel spider distributes impact and crushing forces over the entire rim with no wear or separation found with two-piece designs
  • One piece forged mainshaft eliminates the possibility of separation during operation
  • Mainshaft Position System controls the vertical adjustment of the mainshaft to compensate for liner wear
  • Counterbalanced design makes the crusher ideal for mobile or stationary installations and minimizes the forces transmitted into the supporting structure
  • Mainshaft threads located on a separate steel sleeve reduces stress on the Mainshaft
  • External gear and pinion backlash adjustment simplifies and speeds maintenance
  • Patented step bearing wear indicator identifies worn bearings, eliminating guessing or having to disassemble the crusher to conduct an inspection
  • Top serviceable spider bushing and oil seal shortens maintenance intervals
  • Automatic spider lubrication system ensures the Spider bushing is constantly lubricated
  • Standard manganese concaves for cost effective performance with available alloy and double tiered concaves for longer life and fewer parts
  • Nitrogen charged balance cylinders ensures that step components do not separate in the event of a Mainshaft jump
  • Lubrication and MPS systems include coolers, filters and heaters to ensure oil is prepared and efficiently presented to the crusher
  • Available automation system to monitor oil pressures and temperatures and bearing conditions to ensure a healthy crusher
  • Optimal bushing design allows the crusher to operate as efficiently as possible, minimizing mechanical losses and heat dissipation
  • Available tools facilitates maintenance, increases serviceability, and minimizes downtime (work platforms, Mainshaft stand, concave carrossel, and service trolley)

Benefits

The perfect blend of experience and innovation

The SUPERIOR gyratory crushers combine Metso’s trusted technology with the latest advancements in metallurgy to achieve peak efficiency and high output by offering:

  • A steep crushing chamber and long crushing surfaces for exceptionally high capacity and maximum liner life
  • An extra heavy-duty frame, large diameter integral mainshaft assembly, and a high-performance bearing arrangement provide long life and reliable operation
  • The correct crushing chamber design resulting in optimized production for your application
  • Crusher capacity can be matched to plant requirements by a simple change of the eccentric bushing
  • Due to their placement within the crusher and utilizing the specialized service tools, all internal components can be easily accessed and serviced
