When sourcing an adjustable crusher, you must prioritize the Crushing Ratio and the Adjustment Range of the Discharge Opening (CSS). Ensure the equipment features Hydraulic Adjustment Systems for real-time control of output size. For durability, verify that the Mantle and Concave are made of High-Manganese Steel (Mn13Cr2 or Mn18Cr2) to withstand high-abrasion environments. Additionally, check the Motor Power (kW) and Processing Capacity (t/h) to ensure they align with your specific production requirements.
