Design and Technology

  • Taking into consideration of slurry flow direction and wear conditions in a flotation cell, products are designed by using either thick or thin rubber-filled blades to improve wear resistance performance of rotors and stators.
  • With initial product design completed, finite element analysis and wear analysis are conducted for optimization before a final design scheme is determined.
  • Rotors and stators for flotation machines mainly consist of metal inserts and wear resistant rubber. Metal inserts are of fabricated structure, with advanced flame cutting for material preparation, followed by accurate welding under strict process standard, and are also tested with a dynamic balancer for balance inspection so as to guarantee the strength and balance performance of the skeleton inserts for the products.
