Roller ceramic lagging is an important part and component of the belt conveying transportation system. The lagging drum can effectively improve the operation of the conveying system and protect the metal drum from being worn. The lagging surface of the ceramic rubber sheet can increase the size of the rubber sheet. The surface friction force can effectively prevent the sliding friction between the drum and the belt, reduce the slippage of the belt, and reduce the material adhesion on the surface of the drum, thereby reducing the deviation and wear of the belt, improving the operation efficiency, and making the drum and the belt run synchronously. To ensure the efficient and large-capacity operation of the belt. They are widely used in power plants, coal mines, cement plants, steel, metallurgy, coal, fertilizer, grain depots, ports and other industries.    The drum is the main component for transmitting power. The rubber-coated drum of the belt conveyor generally conveys the mixture of bulk materials (ore, coal), and the equipment operates continuously for a long time, which requires the drum to have high wear resistance, extremely high tensile strength, and resistance to tear properties. The drum is also susceptible to weather (eg rust, sludge) if operated in the open air. The traditional rubber roller is easy to wear, slip, and run, and damage the conveyor belt, resulting in a decrease in the conveying load of the belt conveyor and frequent equipment replacement.   When the drum drives the belt conveyor, it is necessary to increase the friction between the mechanical transmission conveying and the surface of the drum to reduce the mutual wear of the conveyor belt when the surface of the drum slips, provide stable running traction and prolong the service life of the belt and drum.   The wear-resistant ceramic lagging developed by our company is made of corundum ceramic embedded on the surface as the anti-wear layer, and polyurethane, which is famous for wear-resistant rubber, as the vulcanized layer, and then bonded with imported high-strength adhesive. The service life is more than 10 times that of rubber-coated rollers.

Wear-resistant ceramic glue, also known as wear-resistant ceramic adhesive and wear-resistant ceramic adhesive, refers to a high-grade wear-resistant ceramic sheet or lining plate used to paste the wear-resistant ceramic sheet or liner on the surface of the equipment substrate to protect the equipment substrate from wear. Performance adhesive.   It is difficult to realize the connection between the wear-resistant ceramics and the metal parts of the equipment by traditional connection methods such as welding. The use of wear-resistant ceramic glue for bonding to realize the connection between the wear-resistant ceramics and the metal parts of the equipment has been a practice test in recent years. An effective way to connect. After development, this technology has been applied to steel, electric power, metallurgy, mining, cement, port, machinery and other industries and has been widely used and recognized.    Wear-resistant ceramic glue can be used to stick the wear-resistant ceramic sheet very firmly on the surface of the equipment that is severely eroded by the material, prolong the service life of this equipment, and reduce the maintenance of such equipment, so as to reduce the replacement of new equipment and reduce equipment operation and maintenance. The purpose of reducing the production loss of enterprises caused by downtime.   There are many types of wear-resistant ceramic adhesives, and different types of adhesives are suitable for different working conditions. The common types of working conditions are as follows: 1. Equipment washed by ash powder at a temperature below 120°C and equipment subjected to strong erosion or erosion wear of materials 2. Paste the wear-resistant ceramic sheet below 120°C on the top surface and facade of the equipment. 3. It is used to paste the wear-resistant ceramic sheet of the fan impeller. 4. Medium-speed coal mill cones, coarse powder separators, powder discharge fans, coal powder pipes, and other equipment subject to ash erosion, as well as equipment subjected to strong erosion or erosion wear in steel, cement, chemical, and other industries.   The amount of wear-resistant viscose depends on the thickness of the ceramic sheet, and the thicker the ceramic sheet, the more viscose is used. The thickness of the ceramic sheet is 10-30mm, the amount of viscose per square is about 2-2.5kg, the amount of viscose per square of 8-10mm is about 1.5-2kg, the size of the ceramic sheet is less than 6mm, the amount of viscose per square is 1-1.5 kg. It is not that the more glue is used, the better the pasting. On the contrary, the overflow of glue between the ceramic sheet and the ceramic sheet due to the excessive amount of glue will seriously affect the use effect of the ceramic sheet, and will seriously affect the falling off.

The ceramic-rubber composite plate is a composite wear-resistant ceramic-rubber composite plate of ceramic rubber, which adopts an advanced thermal vulcanization process to vulcanize a square or hemispherical wear-resistant ceramic lining and rubber together.   It combines the advantages of the high hardness of ceramics and the high cushioning and anti-fatigue properties of rubber, and can well solve the problem of equipment wear resistance in the process of conveying large pieces of boring. The addition of rubber not only makes the composite board have good anti-wear and anti-corrosion effects but also can prevent production stoppage and reduce noise caused by material accumulation.    Impact resistance: Alumina wear-resistant ceramic lining rubber has good cushioning performance, which can effectively buffer the impact caused by ores falling from a high altitude, while the wear-resistant ceramic lining plate is resistant to wear because the main raw material of the product is alumina. Performance, but the toughness is insufficient, when the impact reaches a certain level, the wear-resistant ceramic rubber composite plate must be selected.   Convenient construction: there is no gap after the liner is installed. The rubber composite lining can be twisted and cut, suitable for installing various special-shaped equipment.   No sticking and no blocking: Due to the high strength and corrosion resistance of ceramics, the phenomenon of equipment sticking and blocking is effectively solved.   The ceramic rubber composite plate has strong wear resistance, impact resistance, and corrosion resistance. Rubber elastomer has an excellent vibration-damping effect, which can reduce the noise generated during material transportation.   The density of ceramic rubber composite plate is lower than that of steel plate, and its weight is light, because of its high wear resistance, it does not need to be replaced frequently, which saves a lot of time and cost for enterprises.   This product has both the wear resistance of ceramics and the impact resistance of rubber. It is suitable for anti-wear of normal temperature material conveying system equipment. It can withstand a certain impact without sticking to materials and not blocking materials. problems encountered.

A wear-resistant pipeline is a composite pipeline with energy saving, emission reduction, wear resistance, and anti-corrosion, which is widely used in electric power, metallurgy, coal, petroleum, chemical, building materials, machinery, and other industries. It can meet the production needs of different enterprises. There are many kinds of wear-resistant pipes in production, and we will introduce them in detail below.   According to the material and forming method of wear-resistant pipes, they are divided into wear-resistant ceramic patch pipes, screw-welded wear-resistant ceramic pipes, integrally formed wear-resistant ceramic pipes, self-propagating composite ceramic pipes, stainless steel wear-resistant pipes, and alloy steel wear-resistant pipes. , Bimetal wear-resistant pipes, high-temperature wear-resistant tortoise shell mesh pipes, high-strength rare earth wear-resistant alloy steel cast pipes, rubber-lined composite steel pipes, wear-resistant backpack composite pipes, etc.    According to other requirements such as industry, conveying medium, working conditions, temperature, pressure, etc. used for wear-resistant pipes, they can be subdivided into the following four categories: Polymer material pipeline: based on polymer compounds (including rubber, plastics, fibers, coatings); Inorganic non-metallic material pipes: non-metallic materials (including glass, ceramics, cast stone, marble) Metal material pipeline: made of metal material; Composite pipes: Made of composite materials, in which one material serves as the base and the other is reinforcement and plays an auxiliary role.   The types of wear-resistant ceramic tubes produced by Yibenuo New Materials are as follows: Centrifugal casting composite ceramic pipes: It is a composite tube of spontaneous combustion high-temperature synthesis and high-speed centrifugation technology. Under the condition of high temperature and high speed, uniform, dense, and smooth ceramic layers and transition layers are formed. At present, it has a good effect in serious wear industries such as straight pipe, elbow, tee, and so on.   All-ceramic lined composite pipes: Due to the high strength, good toughness, good impact resistance, high hardness, wear resistance, corrosion resistance, and heat resistance of corundum alumina ceramics, it overcomes the characteristics of low ceramic hardness, poor wear resistance, and poor ceramic toughness. Therefore, the composite pipe has good comprehensive properties such as wear resistance, heat resistance, corrosion resistance, mechanical shock and thermal shock resistance, and weldability. It is an ideal wear-resistant and corrosion-resistant pipeline for conveying granular materials, grinding, corrosive media, etc.   Adhesive wear-resistant ceramic pipe: It uses adhesive to paste alumina ceramic parts on the inner wall of the pipeline. The production process of this product is simple, the production cycle is long, and the use environment shall not exceed 150 degrees.   Stud welded wear-resistant pipes: The ceramic sheet is pasted on the inner wall of the pipe with high-strength and strong adhesive adhesive, and the ceramic is firmly welded to the inner wall of the steel pipe through small holes. To protect the welding point, the ceramic cap is opened. The production process of this product is more complicated. , the production cycle is long and the cost is high.   One-piece wear-resistant pipes: It is to burn the pipe into a whole and pour it into the steel pipe with a special filler. The inner wall of the pipe fitting is smooth and sealed and has good wear resistance and corrosion resistance. However, this product has a long production cycle and high cost.  

The wear-resistant ceramic patch is a special corundum ceramic made of 95% AL2O3 as raw material, rare metal oxide as a solvent, and sintered at a high temperature of 1700 ° C. According to the different operating conditions of the equipment, suitable wear-resistant ceramics are selected, to satisfy the customer's request.   Wear-resistant ceramic patches are widely used in relevant equipment and pipelines of coal powder transportation in power plants, sintering and dust removal in steel plants, cement plants, etc. The performance of wear-resistant ceramic sheets on the inner wall of coal mills is as follows:    Wear resistance: The content of Al2O3 in the ceramic layer of the ceramic composite steel pipe is more than 95%, and the microhardness is HV1000-1500. It has extremely high wear resistance, and its wear resistance is more than ten times higher than that of quenched medium carbon steel. Better than tungsten drill carbide.   Corrosion resistance: Ceramic is a neutral material with stable chemical properties, excellent corrosion resistance, and acid resistance, and can resist various inorganic acids, organic acids, organic solvents, etc., and its corrosion resistance is more than ten times that of stainless steel.    Excellent heat resistance: The operating temperature of the on-site equipment must be determined before the construction of the wear-resistant ceramic patch, and the viscose with different temperature resistance should be selected at different temperatures, otherwise the wear-resistant ceramic chip will easily fall off as the temperature rises.  

Alumina ceramics is a widely used type of ceramics, but do you know the production process of alumina ceramics? Powder preparation: According to different product requirements and molding processes, the imported alumina powder is prepared into powder materials. The powder particle size is less than 1 mm. If high-purity alumina ceramics are produced, in addition to the alumina purity of 99, it needs to be ultra-finely pulverized, and the particle size distribution is uniform. In addition, in order to reduce the friction between the powder and the wall, it is necessary to add 1% ~ 2% % lubricant.      Molding method: the molding methods of alumina ceramics include dry pressing, grouting, extrusion, isostatic pressing, injection, casting, hot pressing, etc. In recent years, filter press molding, direct solidification injection molding, gel injection molding, centrifugal grouting and solid-free grouting have been developed at home and abroad. Products of different shapes, sizes, complex shapes, and precision require different molding methods.

To prevent the conveyed material from staying at the bottom of the pipeline, the pneumatic conveying device must keep the material moving at a certain speed. There will be collisions and impacts between the material particles in the transfer and the pipe wall, which is the cause of wear and tear of the conveying pipe in the pneumatic conveying device. The wear in the straight pipe section of the pneumatic conveying pipe is very light. The easy-to-wear parts mainly occur at the bends of the pipes, especially when the solid particles impact the outside of the bends of the pipes, which is elbow wear.   Factors caused by pipe wear 1. Friction or rolling wear: surface wear caused by material friction. 2. Scratch wear: Local peeling occurs due to the material going deep into the surface. 3. Impact wear: The surface tissue is partially broken and detached due to the impact of the material.    The greater the roughness of the elbow, the greater the frictional resistance, and the easier the elbow is to wear. Usually the material with less roughness is selected at the elbow; too many elbows are used. The greater the energy consumption, the easier the pipeline is blocked and the faster the wear of the elbow; the smaller the pipe diameter. The greater the resistance to the airflow. The more damaged the pipe wall; the greater the bending angle. The greater the amount of wear.   The elbow is the most vulnerable part when conveying abrasive materials. When the material passes through the elbow, it hits the inner wall outside the pipe due to centrifugal force and inertia. Some particles slide along the inner wall outside the pipe wall; another part of the particles reflect from the outer inner wall to the inner wall inside the pipe. This repeated movement: the material undergoes several collisions. In the middle of the outer wall of the circular section elbow, a pit like a chisel will be produced. Therefore, the impact and friction of the material on the pipe wall is the main reason for the wear of the elbow.

Many metal and non-metal components in many beneficiation equipment are worn out due to continuous work, which affects production efficiency. Therefore, serious wear and short service life of beneficiation equipment have a serious impact on the development of beneficiation production.   The mineral processing equipment adopts industrial ceramic lining, which is mainly used to resist the damage to the pipeline caused by the scouring and wear of the mixed gas and prevent the mixed gas from leaking and polluting the environment due to wear. Grinding ceramic pipes not only makes full use of the high-temperature wear resistance and corrosion resistance of alumina ceramics but also makes full use of the advantages of high metal strength and high toughness. The integrated design is convenient for replacement and installation.    3mm thick wear-resistant ceramic lining is used to replace the original 4mm thick stainless steel wear-resistant layer. The inner surface of the pipeline is polished neatly with an angle grinder. According to the changes of ambient temperature in the season, the cylinder and 6 mm thick 95 alumina ceramic sheet are adhered together with high-strength non-magnetic adhesive under acceptable conditions, and gently beaten with a rubber hammer to make the height of the whole cylinder uniform, After 24 hours of operation, avoid uneven operation of the magnetic separator.   After the wear-resistant ceramic lining is used, the service life of the pipeline is increased from the previous one month to two years. The upgrade and transformation results are very large, which not only reduces the problems caused by wear and tear, but also effectively improves the work efficiency. Adding wear-resistant ceramic sheets to the equipment is not only resistant to high temperature, but also can effectively prevent the equipment from slipping, reduce the frictional impact in the equipment, keep the machinery in long-term production without damage, reduce maintenance, save production costs, and effectively extend the service life of the equipment. Of course The most important point is that wear-resistant ceramic sheets can save energy and reduce emissions, which can effectively reduce energy consumption and facilitate the long-term development of the industry.

Wear-resistant ceramic linings, ceramic pipes, rubber ceramic linings, ceramic rubber rollers, and other products have been widely used in the power industry. Alumina ceramics have strong wear resistance, impact resistance, high strength, light weight, firm installation, and good wear resistance. , which can greatly extend the service life of the equipment. 1. Powder pipeline: Most of the pulverized coal transportation pipelines in the combustion system of the power plant are made of O235 material. The inner wall of the pipeline is severely eroded and worn by fly ash particles during operation. In order to improve the wear resistance of the pipeline, a wear-resistant lining plate with a high-strength structure is selected, which can well avoid the wear of the pipeline and protect the pipeline.   2. Separator: The cyclone separator of the power plant is seriously worn, and the equipment parts are worn through or pierced by coal powder. Wear-resistant ceramic lining plates are used to play a wear-resistant role to prolong the service life of the separator.    3. Coal mill: The rapid grinding cone used in the power plant is seriously worn under the scouring of high-speed pulverized coal particles. The use of wear-resistant ceramic liners can effectively extend the service life of the equipment by 2-3 years.   4. Circulating water pump: During the use of the circulating water pump, the water pump is corroded, cavitated, worn, and corroded due to the reduction in the size of the pump casing and the impeller or the honeycomb surface. Perforations are severely repaired frequently.   Wear-resistant ceramic linings, ceramic pipes, rubber ceramic linings, and ceramic rubber rollers are not only used in power plants but also widely used in steel, coal, chemical, cement, wharf, machinery, and other industries. They are good wear-resistant materials.

After the raw coal is ground into the pulverized coal by the coal mill, it flows in the pipeline in the form of fluid and is transported to the furnace through the coal conveying pipeline. After a period of operation, the inner wall of the pipeline is severely eroded and worn by pulverized coal particles, and the wall thickness becomes thinner. In the elbow, the pipe wall is even worn by the pulverized coal, polluting the environment and reducing the efficiency. In order to improve the wear resistance of the pipeline, the selection of suitable high-strength structural adhesive wear-resistant ceramic lining can well avoid the wear of the pipeline, protect the pipeline and prolong the service life of the pipeline.    Wear-resistant ceramic pipes are made of high-temperature-resistant and strong adhesive to stick alumina ceramic sheets on the inner wall of the pipes, and after heating and curing, a firm anti-wear layer is formed. More than 15 times the steel pipe. The service life of ordinary pipes is half a year to one year, and the service life of wear-resistant ceramic pipes can reach 5-10 years, which greatly reduces the number of equipment downtime and maintenance, and saves a lot of manpower and material costs for enterprises. It is a very cost-effective anti-wear scheme for pulverized coal conveying pipelines.   The service life of the pulverized coal conveying pipeline lined with wear-resistant ceramics is greatly improved. The lined corundum ceramics have high hardness and are resistant to acid and alkali corrosion. , The lining is smooth and does not accumulate material.
