Shell Liner Ball Mill Liner Wear Resistant Casting Variable Part Model Superior Protection

Shell Liner Ball Mill Liner Wear Resistant Casting Variable Part Model Superior Protection

Product Description
Ball mill liner is the core wear‑resistant spare part for ball mills. It improves grinding efficiency and extends mill service life under various industrial working conditions. Precisely cast and customizable, it protects the mill shell from abrasion and impact during material grinding.

Hardness can be customized according to clients’ site working conditions. Excellent wear‑resistant and impact‑resistant performance greatly extends service life of both liners and ball mills.

We adopt premium raw materials including Mn13Cr2, Mn18Cr2 high‑manganese steel and high‑chromium cast iron. High‑manganese steel features good toughness and work‑hardening property, while high‑chromium cast iron delivers high hardness and superior abrasion resistance. Both materials adapt to harsh inner environment of ball mills.

Strict quality control is applied for every batch. Material Test Report, Hardness Report and Final Inspection Certificate are available. Complete tests verify chemical composition and mechanical properties to guarantee high-standard product quality.

Inspection

IQC (Incoming Quality Control)

Verify raw‑material certificates. Sample‑test chemical composition via spectrometer for C, Mn, Cr, Si, S, P. Isolate and reject unqualified raw materials before casting.

IPQC (In‑Process Quality Control)

Check drawing & mold dimension for liner profile and mounting holes. Monitor pouring temperature, sand casting process and quenching‑tempering heat treatment. Mark batch number on each casting after riser cutting. Carry out on‑line patrol inspection throughout production.

FQC (Final Quality Control)

1. Visual check plus MT Magnetic Particle Test to detect cracks, porosity, sand holes and inclusions. Penetrating cracks are strictly forbidden.
   
2. Dimensional inspection: measure overall size, thickness and mounting holes with calipers & special gauges as per customer drawing to ensure fitting tolerance.
   
3. Hardness test: Brinell / Rockwell hardness sampling test according to customer working‑condition requirements.
   
4. Spectrometer re‑check chemical composition on finished castings.
   
5. Actual single‑piece weight verification.

OQC (Outgoing Quality Control)

Cross‑check model, quantity and part numbers against order. Re‑inspect surface condition. Take product photos for archive. Inspect packing (wooden case / steel pallet & anti‑rust treatment). Issue Material Test Report, Hardness Report and Final Inspection Certificate, sent by email or together with shipment.

Non‑conforming Parts Handling

Minor defects can be repaired by grinding with full re‑inspection afterwards. Severely defective castings shall be scrapped and reproduced, and customers will be informed accordingly.
