Alumina Wear-resistant Weldable Ceramic Liner

Alumina wear-resistant weldable ceramic liner as hopper liners are the perfect solution for protecting grinding ball mills from wear, as they allow for a constant use over an extended period of time without any routine maintenance.

There is an oxide film on the surface of the alumina wear-resistant weldable ceramic liner, which will improve the hardness and wear resistance of the lining plate. The principle of its oxide film formation is no different from that of water electrolysis, and can be said to be the same. If current passes through, the cathode of the liner will release hydrogen; not only molecular oxygen, but also ionic oxygen and atomic oxygen are precipitated on the anode of the liner. Generally, molecular oxygen is reflected in the reaction. The aluminum on the anode of the lining tiles is oxidized by the precipitated oxygen to form an anhydrous aluminum oxide film. However, the generated oxygen does not completely react chemically with the aluminum. Some of it precipitates in the form of gas and adheres to the surface of the lining plate, forming Oxide film. The principle of alumina wear-resistant weldable ceramic liner generates an oxide film, which has very good lubricity and insulation properties. It can absorb various lubricants and is very suitable for use in the manufacture of engine cylinders or other wear-resistant parts.

Alumina Wear-resistant Weldable Ceramic Liner performance characteristics:

1. High hardness: Generally, the hardness is greater than HRA80 or more, which is 271.5 times more wear-resistant than steel, and the highest can reach more than 92;

2. Good wear resistance: at least 200 times that of ordinary carbon steel and 10 times that of high-chromium cast iron; the super wear resistance greatly reduces the frequency of maintenance, saving costs and labor;

3. Light weight: the specific gravity of alumina is generally only about 3.6, that of silicon carbide is about 2.7, and that of zirconia is about 6;

4. Good heat resistance: The heat resistance of different wear-resistant ceramics is not the same, but this product is used in the occasion of resistance to particle erosion, and there is no problem with heat resistance.

5. Excelent impact resistance: Its unique stripe design and high-quality buffer layer can resist the impact of large materials, and the toughened ceramic formula ensures that the plate is not easily broken.

Alumina Wear-resistant Weldable Ceramic Liner is mainly used in a variety of equipment for conveying various high hardness and high abrasive granular materials, including electricity, heat, steel, coal, cement, mining, smelting, petroleum, building materials, chemicals, fans, paper, machinery, powder Coal conveying, material conveying system, pulverizing system, ash discharge, dust removal system and other mechanical equipment in industries such as body engineering, grain machinery, and tobacco. Depending on the combination with the metal substrate, it can be used on the inner surface of stationary parts, such as pipes, elbows, separators, chutes, valves, various shells, etc., and can also be used on high-speed rotating equipment, such as various fans. Rotors, impellers, rollers, etc.

A: We have 92% and 95% alumina ceramic tile now.

A: More than 9 Mosh.

A: Widely used in cement plant, chemical, rubber and so on, is the ideal surface wear-resisting material for material transfer equipment in mining, iron, thermal  & powder plants, etc. The life time of the alumina ceramic is about 260 times longer than that of manganese steel and 170 times longer than that of chromel steel.
