Machinery manufacturing: used to manufacture high-precision, high-wear-resistant parts, such as bearings, gears, and guide rails, significantly improving the performance and reliability of mechanical products.
(2) Wear-resistant ceramic lining bricks are usually made of a composite of ceramic materials and matrix materials. Ceramic materials generally use high-alumina ceramics or zirconia ceramics, which have excellent wear resistance and compressive strength. The matrix material is usually steel or other metal materials, which provide the necessary support and toughness. By combining the ceramic layer with the metal matrix, a composite material that is both wear-resistant and sufficiently tough is formed.
Application:
Mining machinery: Protect crushing and screening equipment from ore impact.
Metallurgical industry: Used in high-temperature furnaces and casting equipment due to its excellent high temperature resistance and corrosion resistance.
Power industry: Used to protect coal powder conveying systems and boiler furnaces.
Cement production: Reduce direct contact between conveyor belts and materials and extend equipment life.
Chemical industry: Used in equipment such as ball mills to increase grinding output and fineness, reduce energy consumption and maintenance costs.
(3) Wear-resistant ceramic lining plates is a material with alumina (AL2O3) as the main body, supplemented with other ingredients, and sintered at a high temperature of 1700°C.

(4) Wear-resistant Ceramic Special-shaped Parts
3. Wear-resistant ceramic composite pipe, full name ceramic lined composite steel pipe, is a pipe manufactured using a high-tech production process - self-propagating high-temperature clutch synthesis method.
Features:
High wear resistance: The Mohs hardness of the corundum ceramic lining can reach 9.0, which has extremely high wear resistance and is suitable for conveying abrasive media.
Corrosion resistance: Ceramic materials have good resistance to corrosive media such as acids, alkalis, and salts.
High temperature stability: The ceramic layer has high thermal stability and oxidation resistance, and is suitable for high temperature environments.
Lightweight and high strength: Among pipes of the same specifications and unit length, the wear-resistant ceramic composite pipe is lighter in weight, but has strong resistance to wear and fluid erosion.

Wear-resistant ceramic composite pipes are widely used in power, metallurgy, mining, coal, chemical and other industries for conveying abrasive granular materials and corrosive media such as sand, stone, coal powder, ash, aluminum liquid, etc. Its excellent wear resistance, corrosion resistance and heat resistance make it an ideal wear-resistant pipeline.
Manufacturing process
Centrifugal casting composite ceramic pipe: It is manufactured using "self-propagating high temperature synthesis-high-speed centrifugal technology". The process is simple and the cost is low. It is suitable for long-distance powder transportation.
Patch wear-resistant ceramic pipe: The alumina ceramic sheet is pasted on the inner wall of the pipe through high-temperature resistant strong adhesive. The manufacturing process is relatively simple and the cost is low.
Self-propagating composite pipe: By mixing ceramic powder and metal powder, it is sintered on the inner wall of the pipe using high-temperature synthesis and centrifugal methods. Integrally calcined ceramic pipe: The ceramic powder is sintered into a ceramic pipe according to the mold and then combined with the steel pipe.
4. Two-in-one and three-in-one ceramic composite plates are a composite material that combines ceramic and rubber materials, with excellent wear resistance, corrosion resistance and impact resistance.
Manufacturing process
Two-in-one ceramic rubber composite plates: Through rubber vulcanization technology, high-hardness alumina ceramics are vulcanized and embedded in special rubber to form a ceramic rubber composite. This composite has good cushioning performance and can effectively cushion the impact of ore and other materials falling from high altitude.
Three-in-one wear-resistant ceramic composite plates: On the basis of two-in-one, a steel plate layer is added. Through rubber vulcanization technology, the ceramic rubber composite is vulcanized together with a steel plate with countersunk bolts to form a composite lining with a three-in-one structure. This structure ensures a close bond between ceramics, rubber and steel plates, while providing additional fixing effects.
Performance characteristics
Wear resistance: The ceramic layer has extremely high hardness, which can effectively resist wear and extend the service life of the equipment.
Impact resistance: The rubber layer has good elasticity and impact resistance, can absorb the impact and vibration generated during the operation of the equipment, and protect the ceramic layer from damage.
Corrosion resistance: Both ceramics and rubber have good corrosion resistance and can operate stably for a long time in harsh environments.
Lightweight: The lining plate in the three-in-one structure is more than 60% lighter than the wear-resistant steel plate, and it is very convenient to install and replace.
Application:
Mining: Used for wear-resistant parts of equipment such as ball mills, coal mills, bucket elevators, scraper conveyors, etc. to improve the operating efficiency and stability of the equipment.
Metallurgy: In various equipment in the metallurgical industry, wear-resistant ceramic composite plates can effectively resist the wear of high temperature, high pressure and corrosive materials.
Electricity: In the coal transportation system, dust removal equipment and other parts of the power industry, reduce equipment wear and reduce maintenance costs.
