1. Mutual wear of rubber lining plate and steel ball of ball mill: both the rubber lining plate and steel ball of ball mill are vulnerable parts. During grinding, the steel ball and material of ball mill do throw line falling movement in the barrel Xiamen rubber liner It will collide with steel balls and materials and cause friction. In continuous operation, the rubber lining plate and steel ball of ball mill will be severely worn, which is directly related to the hardness of materials. The greater the hardness of the material, the faster the abrasion speed of the rubber lining plate and steel ball of the ball mill, which may cause equipment damage or even safety accidents in serious cases. In addition, it is also related to the ball of the ball mill. The size and quantity of the ball will affect the service life of the rubber lining plate of the ball mill. If the ball mill is in operation, increasing the amount of steel balls or filling steel balls with larger diameters will increase the wear of the rubber lining plate of the ball mill. 2. The heat treatment process of the rubber lining plate of the ball mill is unreasonable: the unreasonable heat treatment of the rubber lining plate of the ball mill will not only increase the wear of the lining plate, but also affect the yield strength of the lining plate, resulting in the fracture of the bolt of the ball mill under the large shear force. In the actual operation, the staff lacked the understanding of the lining plate material and the heat treatment processing of the ball mill rubber lining plate was insufficient, so the strengthening effect of the ball mill rubber lining plate was not in place and the strength was low. When impacted by steel balls and materials, rubber liner company Plastic deformation often occurs. 3. The material of the rubber lining plate of the ball mill is unreasonable: the material of the rubber lining plate of the ball mill and its heat treatment process are the key to determine the mechanical performance of the lining plate. If the material of the lining plate is not properly selected, its fatigue strength and life will be greatly reduced, which will not meet the requirements of the ball mill, or even plastic deformation or bulge will occur.

Now on the market Xiamen rubber liner There are various models of galvanized air ducts. I believe you are familiar with galvanized air ducts. Do you know the main characteristics of galvanized air ducts? If you don't know, you can have a look. It will be helpful to purchase and use galvanized air ducts in the future. Galvanized air ducts refer to air supply, exhaust and smoke exhaust ducts used in hotels, shopping malls, textiles, chemical fiber, petrochemical, machinery manufacturing, instruments, electronics, medicine, tobacco, food, medical care, storage, office buildings, subway, civil air defense, basement and other projects. Its thickness and specification can vary according to requirements. Generally, when connecting, both ends of the galvanized spiral air duct are always externally connected to the accessories. Galvanized air duct metal air duct is made of various metal materials, commonly including galvanized iron sheet and stainless steel. With the continuous development of the tank industry at present, more and more industries and enterprises have applied to the tank industry, and more and more enterprises have entered the tank industry. Composite air ducts are composed of various inorganic materials, which can be divided into various types according to their composition, but most of them are lightweight, porous, and have large thermal resistance. First of all, the galvanized air duct is exquisite, compact, durable, beautiful, noble and elegant. The support and hanger of iron sheet air duct should be in the form and specification suitable for strength and rigidity according to the national standard atlas and specifications. The supports and hangers of extra wide, overweight and other special iron sheet air ducts with diameter or side length greater than 2500 mm shall be in accordance with the design regulations. rubber liner company High quality galvanized sheet is used. Condensate water pan is molded by molding process. There are no welding seams, welding spots, and thermal insulation materials (applied to industry and buildings) that meet the fire protection standards are connected to the water pan as a whole. The galvanized air duct is small in size, and the installation of drainage pipes and lines is simple and convenient. The left and right connecting pipes and return air modes can be changed at any time to match the site conditions. Galvanized air duct can be installed in any space.
The reason why welded air duct has become the favorite of the market, Xiamen rubber liner Compared with the air duct made of traditional materials, it has obvious advantages in technology, energy conservation, environmental protection and economy. This product has been inspected, tested and proved by the National Building Materials Testing Center, the National Fire Building Materials Quality Supervision and Inspection Center, the National Air Conditioning Equipment Quality Supervision and Inspection Center, the National Non ferrous Metal Quality Supervision and Inspection Center and other relevant authorities, In addition, no smoke is generated in the fire, and the smoke density is only 4, which is 10 to 20 times that of other organic foam materials. In modern buildings, central air conditioning is very common, and ventilation ducts are an important part of the central air conditioning system. According to statistics, China's annual demand is about 100 million square meters, reaching 20 billion yuan. Among all kinds of air ducts, welded air ducts stand out for their unique excellent performance and cost performance, and are becoming the new favorite in the central air-conditioning market. The manufacturing of welded air ducts is highly automated and the production speed is very fast. Ordinary air ducts can produce 20~40 meters per minute. Due to the low price of the raw material galvanized strip steel compared with the whole galvanized steel sheet, and its factory production and specification standardization, the cost is lower than that of rectangular air ducts; In addition, the total cost is low due to the less demand for supports and hangers and the less installation work. Since the four corners of rectangular air duct are prone to turbulence, rubber liner company The effective flow area is reduced. The technology of welded air duct is very close to the international level; In terms of supporting services, more and more enterprises like this company provide high standard services. If there are any suggestions, we hope to see more and more enterprises with a sense of mission for the development of the industry.
The development trend of HVAC duct is production rubber liner Now more and more companies choose advanced spiral duct technology. The advantages of spiral air duct are as follows: 1. Good air tightness. Spiral air duct greatly reduces the connection of air duct and minimizes the leakage between connectors. The typical spiral air duct is 3-6m, but the typical rectangular air duct is only 1-1.5m; At the same time, only one connector is required to connect two spiral air ducts, while a typical rectangular air duct connector requires separate double flanges. 2. Standardized products. The production of spare parts (pipes and connectors) is highly automated and systematic, and has industrialized quality control. 3. Low installation cost. The installation of round duct only needs one third of that of rectangular duct. 4. Save space. Under the same pressure and the same installation space, the spiral air duct with a diameter of 200mm can replace the rectangular air duct with a diameter of 250x150mm. Without increasing the installation space, multiple spiral pipes can be used instead of wider rectangular pipes. Considering various factors, in most cases, spiral pipes require less space than rectangular pipes. Under the same pressure, the installation space of several spiral pipes is equal to or less than that of rectangular pipes. Most rectangular pipe systems require 4 bolts to fix, which will increase 40~80mm in each direction. 5. The pressure drop is low. As we know, spiral duct has lower ventilation resistance than rectangular duct. 6. Precision locking technology. Xiamen rubber liner The mold on the is made of special steel. After years of use, the surface remains unchanged, making the surface of the spiral air duct free of scratches and extending the service life. 7. The perimeter of rectangular air duct with length width ratio of 1:3 at the same section is 40% larger than that of spiral air duct, which means that spiral air duct saves more materials and reduces thermal insulation.
Let's take a look today Xiamen rubber liner How should the maintenance work be done? Firstly, the thickness of galvanized air duct splice plate shall be within the range specified in various specifications. If it is less than the thickness, it is easy to have defects such as cracking and wrinkling due to significant increase of bending force, abnormal damage of forming roll, overload of transmission system, boring, etc. Secondly, in the dedusting system: galvanized air ducts can be used for the collection and transportation of dedusting devices. In terms of air exhaust system: there is a large amount of smoke in the dining room, dining room and hotel kitchen, which needs air exhaust. The galvanized pipe is more appropriate, with good strength, economy and practicality. In air conditioning system: galvanized air duct can be pasted with thermal insulation materials, and the surface is beautiful. In bulk material transportation: in the pneumatic conveying system, some materials with fine loose particles can be transported by galvanized pipes, which has low cost and good effect. In the ventilation system: fresh air is supplied and discharged, harmful gases are discharged outdoors, and outdoor fresh air is sent indoors. The strength of stainless steel plate is greater than that of ordinary steel plate. When stainless steel plate is used for seaming, first of all, a forming test should be carried out to avoid overloading of equipment and excessive wear or mechanical problems. Due to the poor plasticity of aluminum plate, it is easy to crack when biting into forming. Forming test shall be conducted before construction. The last point is that the protection and decoration of the galvanized layer of the galvanized air duct can be significantly improved after passivation treatment, dyeing or brushing light protective agent. and Xiamen rubber liner The fire prevention function of is mainly reflected in that it is nonflammable, but it should be noted that whether the insulation layer is burned depends on the material. We recommend that galvanized air duct materials use nonflammable insulation materials such as centrifugal glass wool.
