Manganese Steel Lining Plates for Concrete & Asphalt Batching Plants

Zhengzhou Sinoma manufactures wear-resistant lining plates (liner plates) cast from premium manganese steel and alloy steel for concrete batching plants, asphalt mixing plants, ball mills and crushers. Every plate is precisely machined to your drawings or machine model for a correct fit, quick replacement and maximum wear life.

What Is a Batching Plant Lining Plate?

A lining plate (also called a liner plate or wear liner) is a replaceable steel plate bolted to the inner surfaces of mixers, aggregate batchers, dryer drums, hot bins, screens and chutes. It protects the main structure from abrasion and impact during mixing and material flow, and is replaced when worn — greatly extending the service life of the host equipment at low cost.

Lining Plates by Application

Concrete Batching Plant Lining Plates

For concrete batching plants we supply manganese and alloy steel liners for twin-shaft and planetary mixers (bottom, side and end liners), aggregate batching bins, weighing hoppers, discharge chutes and skip buckets. The plates resist the constant scraping of sand, gravel and cement, and are machined to match common mixer models with pre-drilled mounting holes.

Asphalt Mixing Plant Lining Plates

For asphalt mixing plants we provide heat- and wear-resistant liners for the drying drum (drum liners and flights), hot elevator, hot-bin compartments, vibrating screen housing and pugmill mixer, together with mixing arms and chute liners. Made from Mn13/Mn18 manganese steel and Cr-Mo alloy, these parts withstand the combined abrasion and high temperature of hot aggregate and bitumen.

Ball Mill and Crusher Liners

We also manufacture ball mill liners and lifting bars for cement, slag and mineral grinding, plus jaw plates, cheek plates, mantles, concaves and blow bars for crushers.

Material Options

• High Manganese Steel Mn13 — excellent work-hardening under impact, ideal for high-impact mixer and crusher liners;

• High Manganese Steel Mn18 — higher work-hardening (500+ HB) for heavy impact and ball mill liners;

• Chrome-Molybdenum Alloy — high hardness and crack resistance for heavy-duty grinding and dryer-drum surfaces;

• Ni-Cr Alloy Steel — good toughness for concrete plant linings and medium-abrasion areas.

Quick-Fit Design and Installation

Our lining plates are available in a quick-fit (easy-install) design with standardized dimensions, pre-drilled or countersunk mounting holes and matched bolt sets. Identical plates are fully interchangeable, so worn sections can be replaced individually instead of replacing the whole set, which shortens downtime. Custom and OEM plates can also be produced exactly to your drawings, samples or worn parts.

Maintenance and When to Replace

Inspect liners regularly for thinning, cracking or loose bolts, especially in high-wear zones such as the mixer bottom and dryer drum. Replace a plate when its thickness is reduced to about one third, when cracks appear, or when the base metal begins to show wear. Keeping spare liners on site and changing them during planned maintenance stops avoids unplanned shutdowns and protects the more expensive host machine.
