SAG Mill

FAQs

• 1. What raw materials can SBM SAG Mill process?

  It is widely applied to hard & abrasive ores including gold ore, copper ore, iron ore, nickel ore, hematite, and also suitable for large-scale aggregate, construction waste, limestone grinding projects. It supports wet grinding as mainstream process.

• 2. What grinding circuit collocation does SAG Mill apply to?

  Two mainstream collocations:1, Single SAG mill open-circuit coarse grinding for low-fineness aggregate production;2, SAG Mill + Ball Mill closed-circuit two-stage grinding system for metal ore flotation/CIL separation, equipped with hydrocyclones for grading.

• 3. What is the essential difference between SAG Mill and traditional ball mill?

  1. Grinding medium: SAG uses ore lumps + small quantity steel balls; ball mill only uses steel balls as media;
  2. Structure: SAG mill large-diameter short cylinder, suitable for coarse primary grinding; ball mill long cylinder for secondary fine regrinding;
  3. Feed size: SAG accepts 0–250mm coarse ore; ball mill feed generally below 20mm;
  4. Production scale: SAG fits large mines over 1000t/d; ball mill applies to small & medium mineral plants

• 4. What liner materials are optional for SAG Mill?

  Standard high chromium alloy steel liner for high-impact hard ore; composite wear-resistant liner is optional to extend service life. Rubber liners are not recommended for SAG due to severe ore impact.

• 5. Is global spare parts supply efficient for SAG series?

  SBM self-owned casting factory stocks full set of core wear parts such as alloy liners and forged steel balls. Multiple overseas spare parts warehouses ensure fast global delivery for all customers.
