について 99% alumina ceramic lower groove cover is a special industrial ceramic component made of alumina (Al ₂ O ∝) with a purity of up to 99% as the main material, through precision molding and high-temperature sintering. It is designed to cope with extremely harsh industrial environments and exhibits excellent performance in wear resistance, corrosion resistance, high temperature resistance, and electrical insulation. It is an ideal substitute for traditional metal and non-metal cover plates and is widely used in fields such as mining, power, steel, chemical, and material transportation.
Core product advantages: Why choose 99 alumina ceramics?
The reason why this product has become the preferred material for key parts is due to its unparalleled physical and chemical properties:
- 究極の耐摩耗性
Data support: The Rockwell hardness is as high as HRA85-90, second only to diamond. Its wear resistance is 266 times that of manganese steel and 171.5 times that of high chromium cast iron.
Value realization: Under continuous erosion by materials such as mineral powder, coal powder, cement, etc., it can greatly extend the service life of equipment and reduce production losses caused by frequent replacement and shutdown. - 優れた耐食性と高温耐性
Chemical stability: It has extremely high resistance to strong acids (such as hydrochloric acid, sulfuric acid), strong bases, and organic solvents, does not produce rust, and effectively avoids material pollution.
Thermal stability: It can work stably for a long time in a high temperature environment of 1600 ℃, with higher short-term use temperature, low thermal expansion coefficient, good thermal shock resistance, and is suitable for high temperature conditions. - High strength and lightweight
Mechanical strength: compressive strength>850 MPa, flexural strength up to 290 MPa, capable of withstanding large mechanical impacts and loads.
Lightweight structure: With a density of approximately 3.6g/cm ³, only half that of steel, it can effectively reduce the overall weight of equipment, decrease the inertia of moving parts, and save energy consumption. - Excellent insulation and surface smoothness
Electrical Insulation: With a resistivity of up to 10 ¹⁵Ω· cm at room temperature, it is an ideal high-temperature insulation material to ensure electrical safety of equipment.
Low adhesion rate: The surface is smooth like a mirror, with a low friction coefficient, which can effectively prevent wet materials from adhering, keep the conveying system unobstructed, and reduce cleaning and maintenance work.
Main application scenarios: Addressing pain points in which industries?
The 99 alumina ceramic lower groove cover is a key component for improving quality and efficiency in the following industries:
鉱業および冶金産業： used for sealing and protective cover plates of vibrating screens, feeders, chutes, feeding pipes and other equipment, solving the problems of rapid wear and perforation of metal cover plates caused by high hardness ores and slag.
Electric power and coal industry: used for observation windows and maintenance covers in coal powder conveying pipelines, dust removal systems, and ash handling systems, resistant to the erosion of coal powder and ash, and possessing high temperature resistance characteristics.
Cement and building materials industry: Installed at the interface of raw material mills, cement mills, powder selection machines, and various conveying equipment to prevent the abrasion of metal parts by cement raw materials and extend the equipment overhaul cycle.
Chemical and Environmental Protection Industry: As a key sealing component for reaction vessels, drying equipment, and corrosive gas pipelines, it solves the dual challenges of corrosion resistance and wear resistance.

The problems solved and the value they bring
Choosing the 99 alumina ceramic lower groove cover is not only a replacement of a component, but also an optimization and upgrade of the production system:
- Solve the pain point of frequent replacement: increase the lifespan of components from several months to several years, significantly reducing the cost of spare parts procurement and inventory pressure.
- Addressing the pain points of unplanned downtime: Excellent durability ensures the continuous and stable operation of the production line, improving the overall equipment utilization efficiency (OEE).
- Addressing the pain points of material contamination: The pure characteristics of no rust and no pollution ensure the quality of the final product (such as food, medicine, high-purity chemicals).
- Addressing the pain point of maintenance costs: Smooth surfaces reduce material adhesion, lower the frequency and intensity of manual cleaning, and achieve cost reduction and efficiency improvement.
- Pain points for addressing safety risks: High insulation effectively eliminates the risk of electrical leakage caused by component damage, improving production safety.
The 99 alumina ceramic lower groove cover has become a core element for upgrading modern industrial equipment due to its ultra long service life, excellent stability, and significant comprehensive economic benefits under extreme working conditions. It is not only a single component, but also a strategic choice to ensure production continuity, improve product quality, and achieve intelligent and green manufacturing.
