Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
METSO · Part Details
Metso SAG Feed Throat Liner
Identify parts for Metso SAG mills and establish the model, drawing, material, manufacturing process and quotation requirements. Start with the installed machine designation and key dimensions, then check drawing and model details, drawing revisions and physical interfaces.
Materials and Processes
Select the material grade and heat treatment for the operating conditions, processed material and equipment specifications. The options below are commonly used; confirm the final grade against the drawing and technical agreement.
Pearlitic Chromium-Molybdenum Steel
Select materials to suit OEM specifications and operating conditions; confirm the final grade and heat treatment against the drawing.
Martensitic Steel
Select materials to suit OEM specifications and operating conditions; confirm the final grade and heat treatment against the drawing.
High-hardness white iron; laminated plate and rubber composite construction is also an option.

Wear Characteristics and Replacement
Common wear modes and maintenance advice. The actual replacement interval depends on duty, material and operating data.
Common wear modes
- Material impact and sliding abrasion reduce surface thickness
- Localized impact causes dents and plastic deformation
- Prolonged wear exposes the base metal
- Wear around bolt fixing points causes the liner to loosen
Replacement criteria
Assess replacement against the remaining-thickness limits in the equipment manual and drawings. Stop the equipment for inspection and corrective action if through-cracks or fastening failures occur.
Material and Process Control
Materials, heat treatment, composite processes and inspection follow the specific drawing, duty and technical review.
Parts with the same name may not be interchangeable across models, drawing revisions, interfaces and materials. Confirm the full model, serial number and drawings before manufacture.
