Based on applications in multiple industries, including cement, steel, and mining, ceramic chute liners are used to convey materials such as ore, coke, coal, and lime. Substituting manganese steel plates with ceramic chute liners can extend equipment lifespan by 10-20 times, significantly reducing maintenance time and alleviating labor intensity for workers. Ceramic chute liners are installed and secured through methods such as direct ceramic adhesive bonding, bolt welding, or pre-fabricated ceramic liner attachments.
In industrial production, such as mining, steel, and cement industries, chutes serve as crucial transport devices within material handling systems. They are commonly utilized for conveying materials like ore, coke, and lime. Chutes share common characteristics, including significant material impact, severe abrasion, and high operating temperatures.
From a tribological perspective, chute wear failures are predominantly attributed to abrasive wear and corrosive wear, with adhesive wear possibly occurring under heavy loads.
To enhance the overall lifespan of chutes, various measures must be taken, encompassing material selection and manufacturing processes, structural optimization design, surface treatments, correct usage, and maintenance. Improving working conditions to minimize wear is one aspect, while installing wear-resistant chute liners is another strategy to enhance surface hardness and wear resistance in chute pathways.
Cast iron is a commonly used wear-resistant material in engineering. Cast iron is classified into three types based on carbon content: gray iron, white iron, and malleable iron. High-chromium cast iron is characterized by high hardness and excellent wear resistance, typically falling within the HRA70-80 hardness range. However, it has drawbacks, including difficulty in cutting and welding. Additionally, cast iron wear plates tend to be brittle and cannot withstand heavy impact loads effectively.
The new generation alloy steel wear plate is primarily composed of chromium, nickel, molybdenum, and other key alloy elements. Its hardness and lifespan surpass those of cast iron wear plates. Alloy steel wear plates are categorized based on alloy content into low-alloy, medium-alloy, and high-alloy wear-resistant steel. They are also classified based on structure into austenitic, pearlitic, and martensitic wear-resistant steel.
Alloy steel wear plates exhibit strong plasticity and excellent mechanical properties, providing resistance to rust and corrosion. The material's toughness and hardness can be adjusted by altering alloy ratios and employing forging processes. However, there exists a trade-off between the hardness and weldability of alloy materials. Higher hardness often results in decreased weldability, making installation challenging. As a result, the practical use of alloy wear plates in heavy wear industries is constrained, with typical hardness levels not easily surpassing HRA60.
Cast stone is a crystalline material processed from silicate, utilizing natural rocks (such as basalt, diabase, and other basic rocks) or industrial waste (blast furnace slag, steel slag, copper slag, chromium slag, iron alloy slag, etc.) as the primary raw materials. Depending on the manufacturing process and formulation, it can be classified into ordinary cast stone wear plates and microcrystalline cast stone wear plates.
Compared to other materials, cast stone wear plates have a simple manufacturing process, low cost, and high hardness. Their wear resistance is several times to over ten times higher than that of steel or cast iron. However, they have drawbacks such as poor plasticity, challenging machining, and relatively low toughness and impact resistance. As a result, cast stone wear plates are less common in today's industrial systems.
Polyethylene high-molecular-weight material boasts excellent wear resistance, good sliding properties, a low friction coefficient, insulation, corrosion resistance, lightweight, and easy processability. It also exhibits effective damping and noise reduction properties, contributing to noise reduction and environmental benefits. Polyethylene material wear plates typically have a thickness ranging from 10 to 30mm.
However, there are drawbacks to polyethylene wear plates. These include low surface hardness and thermal deformation temperature, limited bending strength, and relatively poor creep resistance. They are not suitable for withstanding significant impacts, and their use is constrained in conditions of high temperatures and heavy wear.
Chute wear-resistant ceramic liners are currently one of the most effective and widely applicable materials for chute lining. They are primarily composed of aluminum oxide, transformed into a tetragonal crystal structure (α-alumina) through high-temperature calcination at 1700°C. With a hardness reaching HRA88, second only to diamond, these liners exhibit a density ?.9g/cm³, a flexural strength exceeding 350MPA, impact toughness ?.2J/cm², and an elastic modulus surpassing 317GPA.
Furthermore, with the addition of zirconia oxide to form ZTA ceramics, these ceramic liners acquire strong impact resistance. In heavy wear conditions, their lifespan can exceed 10 times that of manganese steel.
Upon investigation, it has been found that manganese steel liners or old ball mill liners are commonly used as anti-wear liners in mining chutes or coal feeder chutes. However, in actual use, severe wear and frequent replacements are common issues. In some cases, chute liners need to be replaced in less than a week, significantly impacting labor efficiency and safe and civilized production.
Our factory produces high-temperature, impact-resistant wear-resistant ceramic chute liners that can replace manganese steel liners, fundamentally solving the wear problems of these equipment. The high-temperature, impact-resistant wear-resistant ceramic liners involve welding toughened and thick ZTA wear-resistant ceramics onto the equipment using a bolt welding process, creating a robust anti-wear layer. Spherical protrusions can also be designed on the liners to further enhance their impact resistance. For easy installation and replacement, ceramics can be mounted on steel plates and then installed on the equipment through welding or countersunk bolts.
Results from various applications in cement plants, steel mills, mines, and other industries indicate that replacing manganese steel liners with wear-resistant ceramic chute liners can extend the equipment lifespan by 10-20 times, significantly saving maintenance time and reducing the labor intensity of workers.
Installing wear-resistant ceramic chute liners involves several methods and considerations to ensure effective performance and durability. Here's a comprehensive guide on installation and fixing methods for these liners:
Use regular or high-temperature-resistant inorganic adhesive for direct bonding and fixing. It is easy to install and suitable for conditions with minimal material impact and temperatures below 200°C.
For situations involving high-temperature materials or significant impact forces on the material drop point, adopt the bolt welding process to secure wear-resistant ceramics within the equipment. Utilize mechanical self-locking force and inorganic adhesion to ensure that the ceramic blocks do not detach.
Initially, install the ceramics onto steel plates, creating a two-in-one ceramic liner (ceramic + steel plate) or a three-in-one ceramic liner (ceramic + rubber + steel plate). Subsequently, secure it to the equipment through welding or countersunk bolts, facilitating easy maintenance and replacement.

Rockwell hardness of high alumina ceramics is up to HRA80-90 which is second only to diamond and far exceeds wear-resistant steel stainless
The wear resistance of high alumina ceramics is 266 times that of manganese steel and 171.5 times that of high chromium cast iron. According to our investigation & follow-up to the clients, the service life of equipment can be prolonged over 10 times under the same working conditions.
High alumina ceramics are inorganic oxides with extremely stable molecular structure and no electrochemical corrosion, thus they can resist erosion of acid, alkali, salt solutions and organic Solvents.
Working temperature of high alumina ceramics can be as high as 1400℃.
High alumina ceramics have the properties of self-lubricity and in adhesion, the roughness is only 1/6 that of steel pipes thus less flow Resistance.
The density of high alumina ceramics is about 3.6g/cm3, which is only half that of steel, thus easy for construction and installation.
Ceramic tile lined pipe is composed of three layers: outer steel pipe layer, corundum layer, and ceramic glue layer. The inner ceramic layer is white from the surface. The ceramic is generally 95% ceramic, and the temperature is generally below 200°C.
At present, the common ceramic sheets lined with ceramic composite pipes are: ceramic block, dovetail mutual pressure, welding type, mosaic, card slot and so on. It has the characteristics of wear resistance and long service life.
The ceramic tile is pasted on the steel pipe with high temperature wear-resistant glue to play a wear-resistant role, and the pipe is generally white. Generally used for large diameter pipes.
Bends and other profile sections can be clad in whole and this process has changed the traditional practice to fabricate bend and other profile sections by drawing polyline without changing flow pattern of material inside piping, greatly reducing conveyance resistance of material.
The ceramic tiles are pasted to the inner wall of the steel pipe with high temperature wear-resistant glue to play a wear-resistant role.

The perfect choice Resistance to abrasion is superior to all material available on the market
Metals have good ductility but poor resistance to abrasion - which means that abrasion prevention is required when metal pipes are used in high-temperature fluid catalyst service. On the other hand, ceramics possess great hardness and abrasion resistance, but they are brittle. Metal Ceramic double pipe is a hybrid pipe using metal as an outer pipe and a ceramic material for inner pipe segments, applied together to utilize the two materials' advantages. Hence excellent wear-resistance and good corrosion resistance of the ceramics and high strength and toughness of metal can be well combined to get a comprehensive advantage of wear-resistance, corrosion-resistance and anti-scaling. They are suitable for applications in heavy wear working conditions.
Ceramics are among the hardest materials available and provide ultimate wear resistance in piping. In high wear applications, ceramic lined pipes have been demonstrated to be cost-effective by increasing service life and reducing maintenance costs.
