We all know rubber liner Where can I find it? 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). Guangzhou rubber liner 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.
rubber liner Where can I find it? 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. Guangzhou rubber liner The basic production processes include rubber mix processing, cord fabric and canvas processing, rubber tube molding, vulcanization, etc. The manufacturer of acid and alkali resistant rubber hose said that the processing method of the skeleton layer and the forming equipment of the rubber hose are different for different structures and different skeletons.
