How to Choose Wear-Resistant Alumina Ceramic Lining Tiles

When selecting wear-resistant alumina ceramic lining tiles, key considerations include the material's physical properties, structural design, and suitability for working conditions. Alumina content is a critical indicator, typically requiring over 92% to ensure excellent hardness and wear resistance. Density should exceed 3.6 g/cm³, with Rockwell hardness not less than HRA85. For high-impact environments, models with alumina content above 95% are recommended, offering compressive strength over 850 MPa. Additionally, verify compliance with standards such as GB/T 5593 or ASTM C773 to guarantee performance reliability.

The structural design and installation method directly affect service life. Monolithic lining plates suit flat surfaces, while mosaic-style small blocks adapt to curved equipment. Thickness selection depends on particle impact velocity: choose 15-20 mm for flows below 15 m/s, and 20-30 mm for velocities exceeding 30 m/s or with large material impact. The installation method should align with the base plate material: welded types for steel structures, bonded types for non-weldable conditions. Backplate flatness tolerance must be within 2 mm per meter.

The application scenario determines the final selection. In coal grinding systems of thermal power plants, mining conveyor pipelines, or cement plant chutes, products must be chosen based on specific wear mechanisms. Request manufacturer test reports, focusing on wear rate (should be below 0.2 cm³/1.61 km) and thermal shock resistance (cycling times from room temperature to 800°C). Professional suppliers should offer working condition analysis and provide customized solutions based on equipment contours.

What is a dovetail wear-resistant ceramic lining?

图片
Chemshun Dovetail wear-resistant ceramic lining is a wear-resistant lining fixed to the surface of the equipment through a dovetail structure. It is mainly used to prevent internal wear of the equipment. Its design achieves firm mechanical fixation through the clamping of the dovetail guide rail and the ceramic lining   1) Structural features Dovetail design: stable installation through clamping, fits the surface contour of the equipment, reduces stress concentration, and adapts to complex working conditions such as high temperature vibration Ceramic material: mainly alumina ceramic, high hardness (HRA ≥ 82), strong wear resistance, high temperature resistance (about 750 ° C), corrosion resistance 2) Advantages   High wear resistance: Made of high-purity aluminum oxide silicon nitride and other raw materials, it has high hardness and strong wear resistance Corrosion resistance: It can resist the erosion of chemical substances such as acids, alkalis and salts, and is suitable ...

Analysis of the Rubber-Ceramic three-in-one Composite Plate Technology: Materials, Processes and Industrial Applications

图片
In the field of industrial wear resistance, traditional single-material solutions are no longer sufficient to meet the complex requirements of high wear and strong impact in various working conditions. The rubber-ceramic three-in-one composite plate , as a revolutionary solution, has achieved a breakthrough in material performance through a three-layer composite structure design: the ceramic layer resists wear, the rubber layer absorbs impact, and the steel plate provides support. This composite wear-resistant material is now widely used in heavy industries such as power, mining, and metallurgy, and has become one of the core technologies for extending equipment lifespan and reducing maintenance costs. The rubber-ceramic three-in-one composite plate is composed of wear-resistant ceramics, rubber and metal steel plates. The ceramic layer mainly uses high-purity (92%, 95%) alumina powder as the raw material, which is formed by dry pressing or isostatic pressing. After being sintered at a...

How to reduce the production cost of alumina wear-resistant ceramics?

图片
The production cost of alumina wear-resistant ceramics is high. In order to reduce the production cost, the following aspects can be considered: I. Raw material selection 1. Select cost-effective raw materials: Under the premise of ensuring product quality, select alumina powder with relatively low price but satisfactory performance, such as industrial alumina or calcined alumina instead of high-purity alumina powder. At the same time, we can explore the use of a mixture of alumina and other ceramic materials to reduce costs through reasonable proportions. 2. Joint procurement of raw materials: Cooperate with multiple companies for joint procurement and use economies of scale to reduce procurement costs. II. Process optimization 1. Optimize the preparation process: Improve production efficiency, reduce energy consumption and waste generation by improving the preparation process. For example, use advanced sintering technology and mold design to shorten sintering time and reduce energy ...
