Steel Mill Parts: Optimized Wear Life

Grinding Mill Wear PartsUnicast Grinding Mill Parts combined provide a complete system for optimized wear life of grinding mill parts with cost savings and minimum downtimes.

Here’s how:

Customized to Perform

Liners: From Feed Head to Discharge End, Unicast Custom-Made Liners optimize mill performance. Our engineers offer on-site measurement to provide a perfect-fit design and alloy selection to suit your application. Unicast is dedicated to providing high quality products at reduced overall installation and maintenance costs.

Optimum Fit

Grates: Our Head Liners, Partition and Discharge Grates are designed for efficient mill performance with reduced maintenance needs. Cast in martensitic chrome-moly steels with a 350 to 450 BHN hardness, Unicast Grates are cast for high strength and optimum fit.

Cast for Abrasion Resistance

Shell Liners: Unicast Shell Liners are cast in materials ranging from chrome-moly steels to high chrome white iron. A minimum hardness of 450 to over 650 BHN ensures maximum strength and a significantly longer wear life. We offer Shell Liners in single, multi-lift and classifying styles for efficient grinding performance.

Long Wear Life

Diaphragm Screens: Water-jet cut from AR400 plate for longest wear life. Custom-made for convenience. Short delivery times.


Abrasion-Resistant Rubber: Up to 4X the Wear Life of Steel

Rubber Mill LinersUnicast abrasion resistant rubber includes three proprietary rubber compositions with different strengths and hardnesses to suit all applications. Pressure-molded to ensure highest density. Customized to suit. Perfect-fit design engineered to improve your bottom lines.

Advantages of Unicast Rubber Liners

1. Longer Wear Life: Unicast Rubber Liners are pressure molded to ensure highest density and engineered for maximum abrasion resistance. Industry recognized as delivering 1.5 – 4 times the wearlife of steel liners.

2. Reduced Weight Lowers Costs: Rubber liners are 75 to 80% lighter than steel liners, increasing energy efficiency of the mill by 15%. Less stress on the mill for reduced maintenance.

3. Leakproof: Rubber liners are perfectly sealed to eliminate opportunity for slurry leakage and corrosion of the shell.

4. Easy to Install: Quick and easy installation of light-weight liners minimizes down times and improves safety.

5. Reduced Noise Levels: Reduce noise levels by 8-10dB. Environment friendly for safer working conditions.

6. Customized to Suit: Unicast Rubber Liners are customized to suit any application. On-site measurements and perfect-fit design engineered to improve your bottom lines.

7. Easy Inventory Control: Predictable wear life of rubber liners allow for advanced ordering and deliveries providing additional cost savings. Contact Unicast for more information.
