In the field of industrial equipment protection, the wear resistance, impact resistance and chemical stability of materials are the key factors determining the service life and production efficiency of equipment. The rubber-alumina ceramic two-in-one liner, with the high hardness, excellent wear resistance of alumina ceramic and the elastic buffering and sealing properties of rubber, has become the ideal choice for equipment protection in many complex working conditions.

I. Characteristics and Advantages of Ceramic Rubber Plates

Alumina ceramics, with a Mohs hardness of 9 and a low coefficient of friction, can effectively resist strong scratching and cutting wear from materials. Moreover, it has strong chemical stability and remains stable in corrosive environments such as acids and alkalis. Rubber, on the other hand, has excellent elasticity and toughness, capable of absorbing over 70% of impact energy, reducing vibration and noise during equipment operation. It also has outstanding sealing performance, preventing material leakage. When combined through high-strength adhesives, the wear resistance of the composite liner is significantly improved by 3 to 5 times compared to single-material liners.

II. Mining Industry: Exceptional Protection for High-Impact Abrasive Environments

In the mining and processing stages, equipment such as crushers and ball mills are subjected to frequent impacts and grinding by the ore. After a copper mine adopted a two-in-one rubber-alumina ceramic liner for its ball mill, the liner replacement cycle was extended from the original 8 months to 2.5 years, and the annual maintenance cost was reduced by 45%. This was mainly due to the wear-resistant protection provided by the alumina ceramic layer against the sharp edges of the ore, as well as the buffering effect of the rubber layer against the high-speed drop (with a speed of 35m/s) impact. In the ore transportation system, when the chutes and hoppers were equipped with this liner, not only was the wear of the equipment by the materials reduced, but also the elasticity of the rubber reduced the phenomenon of material jamming, resulting in a 18% increase in transportation efficiency.

III. Power Industry: Reliable Assurance in High-Temperature and High-Dust Environments

The interior of the coal grinding machine in a thermal power plant is exposed to a high-temperature environment ranging from 80 to 120 degrees Celsius, and is also subjected to the abrasive action of high-concentration coal powder. Traditional liners are prone to thermal fatigue and erosion problems. The rubber-alumina ceramic dual-layer liner is made by combining high-temperature-resistant rubber (with a temperature resistance of up to 220 degrees Celsius) and alumina ceramic, extending the service life of the inner lining of the coal grinding machine to over 4,500 hours. In the pneumatic ash removal pipeline, facing the erosion of ash particles with a flow velocity of 28 m/s, the wear rate of this liner is 70% lower than that of ordinary liners, effectively ensuring the long-term stable operation of the pipeline.

IV. Metallurgical Industry: Durable Solutions in Complex Medium Environments

The dust removal system of the steelmaking converter and the coal injection pipeline of the blast furnace are confronted with the combined challenges of 300 - 500℃ high temperature, high dust content and strong corrosive media. After applying the rubber-alumina ceramic dual-layer lining to the coal injection pipeline in a certain steel plant, the annual wear of the pipeline decreased from 9mm to 2.5mm. At the same time, the excellent sealing performance of the rubber layer prevented dust leakage and improved the working environment of the workshop. In the vibrating screen of the ore pre-treatment equipment, the elastic buffering function of the lining reduced the mechanical loss of the equipment by 35% and prolonged the service life of the equipment.
