Ball Mill Spare Parts
Wear-resistant components for raw material mills, cement mills and coal mills. We supply cast steel liners, rubber liners, diaphragm plates, grinding media and structural parts — all available in standard alloy grades or custom compositions to match your specific operating conditions and mill model.
Ball Mill Liner (Cast Steel)
Shell liners, head liners and lifter bars precision-cast in high-manganese or high-chromium alloys. Designed to maximise grinding efficiency and service life.
| Material | Mn13, Mn18Cr2 / Cr15–Cr26 / ZG40CrMo |
| Hardness | 45 – 65 HRC |
| Weight range | 5 kg – 500 kg per piece |
| Applications | Cement, mining, power plant, chemical |
| Custom | Size, alloy grade & profile to drawing |
Ball Mill Rubber Liner
Lightweight rubber liners that reduce noise, lower mill load and extend service life compared to steel alternatives — ideal for fine grinding applications.
| Material | High-grade abrasion-resistant rubber |
| Thickness | 40 mm – 100 mm (customisable) |
| Hardness | 65 – 75 Shore A |
| Liner types | Shell, end liners, lifter bars |
| Service life | 1.5 – 2× longer than steel in fine grinding |
Grinding Steel Balls
Forged and cast grinding balls for ball mills and rod mills. Consistent roundness, uniform hardness throughout and low breakage rate — reducing media consumption and downtime.
| Material | High-Cr steel (Cr10/15/18), Forged B2/B3, ZGCr5Mo |
| Hardness | 55 – 65 HRC |
| Size range | Ø 20 mm – Ø 150 mm |
| Weight | 0.1 kg – 10 kg per ball |
| Custom | Size and alloy to specification |
Ball Mill Diaphragm
Intermediate and outlet diaphragm assemblies for compartment separation and airflow control. Slotted plates, blind plates and centre cones supplied as complete sets.
| Material | Mn13, Mn18Cr2 / Cr15–Cr26 / Alloy steel |
| Hardness | 45 – 65 HRC |
| Components | Slotted plates, blind plates, centre cone |
| Weight | 5 kg – 500 kg per section |
| Custom | Slot width, plate profile and OD to drawing |
Ball Mill Girth Gear & Pinion
Large-diameter girth gears and matched pinion sets for ball mills. Cast or fabricated in alloy steel and finish-machined to tight tolerances for smooth, low-vibration drive performance.
| Material | 42CrMo / ZG310-570 alloy steel |
| Tooth type | Single-row or double-row helical |
| Diameter | Up to 8 m OD (custom to drawing) |
| Supply | Gear + pinion as matched set or separate |
| Finish | Precision machined, gear-ground available |
Ball Mill Trunnion
Feed-end and discharge-end trunnions cast in carbon steel and machined to dimensional tolerance. Trunnion liners also available to protect the base casting from wear.
| Material | ZG230-450 carbon steel |
| Types | Feed trunnion, discharge trunnion, liners |
| Machining | CNC turned and bored to drawing |
| Surface | Machined bearing seat and flange faces |
| Custom | All diameters and lengths to specification |
