We all know Acetylene tape Price The noise pollution in industrial production is very serious, and noise pollution is also an important factor affecting workers' enthusiasm for production. Ball mills were once a major source of noise in mining equipment. In order to reduce the noise generated by ball mills, protect the physical and mental health of workers, improve workers' enthusiasm for production, and create greater profits for the company, Through the efforts and research of domestic and foreign industry experts, the ball mill liner has been transformed. Through repeated tests and comparison, it is found that the noise generated by the rubber liner and the manganese steel liner of the ball mill is far less than the manganese steel liner when the technical parameters are up to standard. According to the data provided by the noise monitoring station and the concentrator, We analyzed the noise intensity and the economic benefits: the domestic ND2 precision sound level meter and octave filter were used for detection, and the sound level meter was calibrated by the provincial sound level meter measurement and verification station; There is no sound insulation room in the ball mill workshop. The monitoring points are arranged according to the position of the ball mill and the flow of workers to observe the mechanical operation, 2m away from the sound source. One monitoring point is respectively set on the left and right of the east and west of the workshop and in the middle of the two ball mills. The measurement method is in accordance with the Noise Detection Specification for Industrial Enterprises. As the noise in the workshop is continuous and steady, sound level A is used as the evaluation basis. The rubber lining plate is manufactured by Hainan Rubber Lining Plate Factory according to the ball mill shell structure and the original manganese steel lining plate specification (1.4mx0.74mX0.07m). Wuhan Acetylene tape First, take out the manganese steel lining plate in the ball mill barrel, and then install the rubber lining plate in the barrel in turn (front and back). Each ball mill is installed with 48 pieces. First, use the pressure strip to compress, and then use the screws to fix the rubber lining plate on the ball mill barrel, so as to prevent falling off when rotating. The noise intensity of the ball mill workshop with manganese steel liner is 94-103dB (A), while the noise intensity of the ball mill workshop with rubber liner is 87-92dB (A), and the noise reduction difference is 7-11dB (A). The rubber liner has good noise reduction effect.

Many people have never understood wear-resisting Acetylene tape It is better to use cast iron or rubber lining plate, so today I will give you a detailed analysis. The lining plate of the ball mill can tell you for sure that it is better to use rubber lining plate, which is also a trend for rubber lining plate to replace manganese steel lining plate. The rubber lining plate has many advantages that can not be achieved by manganese steel lining plates such as cast iron, so it has more advantages. One of the advantages of using cast iron or rubber liner for ball mill liner is that the noise of rubber liner is lower. In the process of grinding the rubber lining plate with materials, the noise is lower because it is not directly rubbed. Moreover, the rubber lining plate can throw the steel ball up for the second time to form the second grinding of materials, which makes the grinding of materials more thorough and the grinding fineness more uniform with good effect. In addition, the rubber lining plate can reduce the noise by an average of 30 dB compared with the noise of the cast iron lining plate, making it acceptable. Another important reason is energy saving. Energy consumption is an unavoidable problem for users of ball mills, because the cast iron lining plate is heavy in quality, Acetylene tape Price Therefore, when the motor drives the lining plate, it will consume a lot of power. The rubber used by the rubber lining plate itself is light, so the electric energy consumed by the motor when driving is very small, which can be more than 10000 yuan of electric energy a year.

Wuhan Acetylene tape It is one of the most common rubber products in life, used to transport various gases and liquids. Natural rubber, synthetic rubber and reclaimed rubber in rubber products can be used for the consumption of rubber sand blasting pipes. When reclaimed rubber is used to consume odorless rubber sand blasting pipe, care must be taken in selecting reclaimed rubber and formula design to meet the performance requirements of odorless rubber sand blasting pipe. When using recycled rubber to consume odorless rubber sand blasting hose, what problems should we pay attention to? The selection of reclaimed rubber for odorless rubber sandblasting hose is the basis for determining the quality of rubber, whether it is environmental protection rubber products or various odorless rubber products. When using reclaimed rubber to consume odorless hose, choosing odorless reclaimed rubber is the top priority. Application of odorless reclaimed latex, odorless reclaimed tire rubber, odorless reclaimed nitrile rubber and odorless reclaimed ethylene propylene rubber in reclaimed rubber products. The odorless butyl reclaimed rubber can be used for the consumption of odorless rubber sandblasting pipes. In addition, odorless hb isoprene reclaimed rubber can also be used for consumption of odorless rubber sandblasting pipes. In actual consumption, the raw materials of odorless isoprene reclaimed rubber (PP reclaimed rubber) are isoprene unvulcanized composite rubber and isoprene bottle stopper. They have strong viscosity, aging resistance and temperature resistance, and are ideal for odorless hose consumption to ensure quality and reduce costs. Pay attention to the vulcanization of odorless rubber sand blasting pipe. as everyone knows, Acetylene tape Price The design of vulcanization system of reclaimed rubber products directly affects the quality of rubber products, and the odorless rubber sand blasting pipe of reclaimed rubber is no exception. When using reclaimed rubber to consume odorless rubber sand blasting pipe products, vulcanizing agent, accelerator and other additives must be combined with odorless additives such as accelerator STT and accelerator D; When vulcanizing the rubber of odorless rubber sand blasting pipe, it is better to vulcanize at low temperature for a long time, which will cause full reaction to the rubber.

wear-resisting Acetylene tape It will burst for a long time due to frequent and severe pressure shocks. This situation is usually not caused by excessive static pressure, but is related to the strength and frequency of pressure shock. During the operation of construction machinery, the oil pressure in the oil resistant hose will rise or fall repeatedly, and then it will form frequent pressure shocks to the oil pipe, causing the oil seal of each part to become more damaged, the oil resistant hose will bubble and break, and the pipe joint will become loose and leak. Therefore, in the process of operation, the valve rod should not be pulled too hard, and it needs to be gentle. The application temperature of the oil in the oil resistant rubber hose is too high, resulting in aging and bursting of the rubber hose. During the operation of construction machinery, the hydraulic system will cause the oil to become hot due to power failure, and the influence of external temperature (especially in summer) will cause the oil temperature to rise sharply. The higher the oiling temperature is, the easier the rubber hose ages, the worse the elasticity is, the lower the strength and sealing function are, and the oil resistant hose will burst quickly. Therefore, Acetylene tape Price During operation, when the temperature rise of the hydraulic system is too high or too fast, the causes should be found and eliminated in time. Necessary cooling measures shall be taken for summer operation, especially continuous operation.

Wuhan Acetylene tape Vulcanization of technical performance indicators is an important process to enhance the adhesive strength between rubber and reinforcement layer and make it a whole in rubber hose manufacturing, and also an important link to ensure and improve product quality. In order to obtain good pulse performance and service performance of steel wire reinforced rubber hose, in addition to reasonable structure and formula, it is necessary to ensure the compactness of vulcanized hose. In order to meet this performance requirement, the traditional vulcanization method is to wrap the water in water cloth on the semi-finished hose before vulcanization, make braided hose or steel wire for reinforcement and fastening, and vulcanize in batches with steam vulcanization tank. Since the performance requirements of medium and low pressure hoses are low, the rubber hose can also be directly put into the curing tank without fastening. Although water wrapped cloth vulcanization can also increase the compactness of the hose, its appearance is poor. In order to obtain the smooth outer surface of the hose, the lead coating vulcanization method is widely used at home and abroad. For decades, people have been using this method as an effective method to vulcanize and strengthen rubber hoses, especially high-pressure rubber hoses. So far, many domestic and foreign manufacturers are still using this method to produce rubber hoses. But the fatal disadvantage of this method is that it pollutes the environment. Acetylene tape Price The main control function of the air compressor station unit is to exhaust more air. According to different structures, it can be divided into full hose, cloth hose, steel braided hose, etc. According to different uses, it can be divided into air hose, water suction hose, water delivery hose, heat resistant hose, acid (alkali) resistant hose, oil resistant hose and special hose., It can be closed within the specified range.

The hard core method adopts the core extrusion process to extrude the inner rubber tube blank, which directly uses the extruder to cover the inner rubber tube blank on the iron core, instead of the traditional casing process, and simplifies the process flow. Wuhan Acetylene tape The billet forming adopts the process method of intertwining outer film and steel wire braiding forming. Similar to wrapping water wrapped cloth, the overlapping width is 1/2 of the film width. This process method can replace the method of wrapping outer film by extruder or by hand, reducing energy consumption and cost. We all know that the reinforcing layer and reinforcing layer of the rubber hose are the main force bearing parts, which are used to bear the load pressure. The factors determining the stress condition of the reinforced layer of the rubber hose are determined by the tension of the braided steel wire and the braiding angle. The high-speed steel wire hose braiding machine developed by our factory has introduced the advanced technology of foreign braiding production lines, and integrated the characteristics of domestic braiding machines. It integrates the advanced functions of hydraulic brake hose braiding production line, such as horizontal mechanical transmission, automatic lubrication, and so on, to develop equipment with high productivity and high degree of automation. The range of braiding diameter can be achieved Ф 6— Ф 25 Long core rubber hose (reinforcement layer). It fills the gap of domestic knitting production equipment, which can be widely used in rubber and plastic hose, rubber hose (reinforcement layer) knitting production equipment. The structure of high-pressure rubber hose is composed of four parts: inner liner, inner rubber layer, skeleton layer, middle rubber layer and outer rubber layer. Acetylene tape Price In case of direct contact with the conveying medium, the synthetic rubber with good medium resistance, high tensile strength, high constant tensile stress, small compression permanent deformation and easy processing is usually selected. In order to meet the use requirements of strong polar medium resistance, the inner liner is composed of polytetrafluoroethylene layer and rubber layer, and a layer of film or adhesive is added on the surface of the inner liner to improve the adhesion with the skeleton material.
