Oxygen band Price It has become the standard configuration of the modern new ball mill, but many problems may occur during the use or installation of the rubber lining plate, which will cause the failure of the rubber lining plate of the ball mill. Here is a brief introduction to the causes of the more common failure of the rubber lining plate of the ball mill. The design and installation are not professional and reasonable. The design and installation are also common problems for many novice manufacturers. For example, the bolt holes for fixing the ball mill lining plate are square, which will cause stress concentration and fracture. Adjust the size of lining plate to control the gap between lining plates at about 8mm; The installation quality of lining plate is very important to the safe operation of ball mill. First, tighten the fixed wedge symmetrically, put the lining plate in sequence, and then use the tightening wedge to secure it; Therefore, professional installation guidance can easily avoid these problems. The reason why the rubber lining plate of the ball mill does not match the steel ball is relatively common, and it is easy for many novice manufacturers to ignore and make mistakes. During the operation of the ball mill, the rubber lining plate of the ball mill, materials and steel balls promote the normal grinding and crushing of the ball mill due to the interaction of forces. The hardness of materials is related to wear resistance, and the wear resistance increases with the increase of hardness, Nanning Oxygen band It is a pair of friction pairs, and the increase of hardness of one side will cause the wear of the other side to increase. Therefore, the high wear-resistant rubber lining plate is matched with the high wear-resistant steel ball, and the low wear-resistant rubber lining plate is matched with the low wear-resistant steel ball, so as to ensure the normal wear of the rubber lining plate of the ball mill and extend the service life of the ball mill.

production Oxygen band 1. During the molding of rubber products, the cohesive force of the elastomer cannot be eliminated due to the large pressure pressing. During the molding and mold release, extremely unstable shrinkage (the shrinkage rate of rubber varies due to different types of rubber) often occurs. It must take a period of time before it can be gentle and stable. Therefore, at the beginning of the design of a rubber product, no matter the formula or the mold, it is necessary to carefully calculate the matching. If not, it is easy to cause dimensional instability of the product, resulting in low product quality. 2. Rubber belongs to thermosetting elastomer, while plastic belongs to thermosetting elastomer. Due to different sulfide types, the temperature range of rubber molding and curing is quite different, even affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber products need to be properly adjusted at any time. If not, there may be differences in product quality. 3. The rubber product is the rubber mixture made from rubber raw materials after mixing in the internal mixer as the raw material. The formula is designed according to the characteristics of the required rubber products during mixing, and the required product hardness is determined. The product is molded by the rubber plate vulcanizer. After the product is formed, flash processing shall be carried out to make the product surface smooth without burrs. 4. The aging test of rubber products belongs to the category of aging test. Rubber aging refers to the phenomenon that the performance and structure of rubber and products are changed due to the combined effect of internal and external factors in the process of processing, storage and use, thus losing their use value. Oxygen band Price It is characterized by cracking, tackiness, hardening, softening, chalking, discoloration, mildew, etc. The following conditions shall be met when the ball mill uses the rubber lining plate: 1. The hardness of the ground material. The iron base alloy is similar to the rubber lining plate for materials below medium hardness, and the rubber lining plate is superior for materials above medium hardness. 2. The temperature of rubber lining plate is generally 70 ℃ - 90 ℃, and it can reach 110-130 ℃ under special circumstances. The temperature should be lower during dry grinding. 3. Feed size. Generally, the ball mill shall be more than 20-25mm; For the autogenous mill, the feeding particle size can be larger because no steel ball is added.

Many people don't know much about spiral tube. In fact production Oxygen band It is very extensive. Spiral air duct is mainly used to connect the two places for ventilation. Spiral air ducts (stainless steel and galvanized iron sheet) are widely used in the market. Spiral air duct market is generally divided into three categories according to material: galvanized spiral air duct, stainless steel spiral air duct and composite spiral air duct. Among them, the stainless steel air duct has good quality and strong applicability, but its price is high. The return air duct of purification system, central air conditioning ventilation duct, industrial air supply and exhaust duct, environmental protection system suction and exhaust duct, mine gas drainage duct, mine coating duct, etc. The spiral duct is first used for ventilation and cooling, which belongs to the category of air duct. It is named according to its purpose, but it can also be used in other places, even for drainage, drainage or as a container, which cannot be called a pipe. Named according to the structure, it should be called spiral grooved thin-walled tube, because it is mainly made of metal, also called spiral grooved metal tube. According to the material name, there may be several names: galvanized (any zinc) (galvanized) (iron), spiral pipe, stainless steel spiral pipe (stainless steel acid resistant steel), aluminum (aluminum) spiral pipe, or in order to distinguish from the existing acid resistant stainless steel pipe, Oxygen band Price It can be called ultra-thin stainless steel pipe, because it can use 0.3mm or even thinner to roll stainless steel strip.

The reason why welded air duct has become the favorite of the market, Nanning Oxygen band 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, Oxygen band Price 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.

Oxygen band Price Precautions ① The acid and alkali resistant rubber hose used shall not only be oil resistant, but also be pressure resistant, heat resistant, cold resistant, wear resistant and aging resistant. ② The rubber hose should not be too long or too short, generally 1.4 meters. ③ The interface is tight and can be fastened with thin iron wire or clip to prevent falling off and air leakage. ④ It is forbidden to pull acid and alkali resistant rubber hose from one room to another or through walls, floors and floors to prevent accidents caused by rubber hose breaking and falling off. ⑤) The acid and alkali resistant rubber hose should be placed in a place where it can be seen frequently, so that it is easy to detect leakage. Check whether the rubber hose leaks after each bottle change. ⑥ Do not replace acid and alkali resistant rubber hose with universal rubber hose. Since the full rubber hose does not contain a skeleton layer, it is only necessary to use a press out machine to press out the hose; The cloth clamping hose needs to use a molding machine that wraps the adhesive tape on the inner adhesive layer; When forming the suction hose, first wrap the metal spiral wire and then wrap the inner rubber; Special fabric knitting machine or winding machine shall be used for knitting and winding hose; Knitting machine is required for knitting hose. Nanning Oxygen band The basic production processes include rubber mix processing, cord fabric and canvas processing, rubber tube molding, vulcanization, etc. The acid and alkali resistant hose manufacturer said that the processing method of the skeleton layer and the hose molding equipment are different for different structures and different skeletons.
