High Manganese Steel Ball Mill End Liner Cast Wear Plate for Mineral Grinding Equipment

High Manganese Steel Ball Mill Grate End Liner Cast Wear Plate with Discharge Holes for Mineral Grinding Equipment

Product Description

The ball mill grate end liner serves as a critical wear resistant casting mounted onto the ball mill end cover. Differentiated from solid end liners, this grate-style liner features regularly arranged discharge openings. It not only shields the mill end casting from continuous impact, abrasion and scouring caused by grinding balls and ore slurry, but also controls pulp flow and particle size discharge inside the grinding chamber. The curved casting profile is precisely manufactured to match the mill head curvature, ensuring seamless assembly and stable material classification during operation. Our high manganese steel grate end liner possesses outstanding impact hardening property. Under repeated striking from grinding media, the working surface gradually increases its hardness, delivering long-lasting wear resistance and effectively cutting down the frequency of part replacement and operational maintenance cost for mineral concentrators.

We are a professional foundry dedicated to heavy-duty mining casting and forging spare parts. We supply a wide selection of material grades to match varied ore characteristics and grinding intensity, including high manganese steel, high chromium cast iron, alloy steel and ductile iron. Our product range covers full series wear components such as ball mill liners, jaw crusher wear plates, AG mill and SAG mill liners, plus other custom mining mechanical castings. We accept OEM and ODM orders according to customer drawings, physical samples and on-site working parameters. Our factory has accumulated abundant experience manufacturing large wear castings for mining, quarry and cement projects all over the world.

The hole size, hole layout, plate thickness and overall outline of the grate end liner can be customized to match different mill models and grinding process requirements. We optimize the transition structure around each hole to avoid stress concentration and prevent cracking under cyclic heavy impact during continuous production cycles.

Applications

Our ball mill grate end liner is widely applied in mineral processing plants, metal and non-metal ore mines, cement works and metallurgical grinding production lines. It is generally installed at the discharge end of grate discharge ball mills. The special perforated grate structure is essential for closed-circuit grinding systems, where controlled pulp outflow and coarse-fine particle separation are required. The liner can maintain reliable performance under severe working conditions, including heavy impact, abrasive slurry and 24-hour continuous running in mining sites.

Production and Quality Inspection

All grate end liners go through dedicated heat treatment procedures to refine internal grain structure, eliminate residual casting stress, and achieve the required balance of hardness and impact toughness. We carry out a complete set of strict inspection for every finished casting, covering hardness test, 3D scanning, magnetic particle test MT, ultrasonic test UT, chemical composition analysis, dimensional inspection and metallographic analysis.

Chemical composition analysis strictly regulates alloy element proportion to meet the designated material standard. Hardness testing evaluates surface wear resistance and impact performance. 3D scanning verifies curved contour, hole position accuracy and assembly dimensions. MT and UT non-destructive examinations detect internal shrinkage, porosity and surface micro cracks. Metallographic analysis checks the uniformity of metal microstructure. Full dimensional inspection ensures all key dimensions stay within drawing tolerances. Each liner must pass full inspection before shipment. Third-party inspection can be arranged upon client request. All inspection records and test reports are properly archived and traceable for each production batch.

Support and Services

We provide all-round professional technical support for global buyers. Our engineering team can carry out working condition assessment, material grade recommendation, structural optimization suggestion and on-site installation guidance. Official documents including material certificates, hardness reports and non-destructive testing reports can be provided on demand. We support custom manufacturing for different sizes, thickness and grate hole patterns to fit various ball mill specifications. Our team has rich export experience for mining wear castings and is familiar with international standards of grinding mill spare parts. We respond quickly to technical inquiries and quotation requests.

We also provide after-sales technical support, including routine maintenance guidance and troubleshooting consultation during equipment operation. Our objective is to help customers minimize unplanned downtime and maximize grinding productivity.

Packing and Shipping

Multiple export packaging choices are available based on liner dimension and weight, including fumigated wooden cases and heavy duty steel pallets. Liners will be securely fixed and protected to prevent scratches, collision and deformation during sea or land transportation. Anti rust coating is applied to casting surfaces to withstand moisture during long ocean transit and overseas warehouse storage. Sea shipment is our primary transport option for these heavy castings. We can comply with customer requests for packing, marking and shipment scheduling to guarantee goods arrive safely and intact. For time-sensitive orders, we can coordinate suitable transport plans. All packages are clearly marked with product information and handling instructions to facilitate customs clearance and on-site receiving.
