We all know that machinery and equipment such as sand making machine generate a lot of noise when they are working. Noise pollution is also a kind of environmental pollution. Noise not only plagues workers in frontline production but also affects the daily life of the surrounding residents. So how to effectively reduce the production process of sand making noise problems, is to lift you from the following aspects:
1, sand production process in the high-pressure, high-speed airflow by reducing the pressure drop and reduce the flow rate, or change the shape of the airflow nozzle to indirectly reduce the noise.
2. Controlling the use of additional barriers to prevent the spread of noise in the production line of sand making use of barriers such as earth slopes, woods, bushes or tall buildings that are not afraid of noise, preventing the spread of sound. The sand production line uses the directivity of the sound source to control the noise, such as venting the exhaust towards the wilderness or sky to reduce the impact on the surrounding environment.
3, the entire production line to take sand muffler, sound absorption, sound insulation, vibration isolation, vibration and other measures to reduce the noise from the source and transmission of noise.
4, the noise of the recipient's protection: take workers rotation homework, shorten the workers into the high noise environment working hours. Personal protection of workers, such as wearing headphones, ear plugs and other anti-noise supplies.
5, sand making daily maintenance, regularly check whether the parts are loose, aging, etc., to reduce the failure rate of sand making machine, and effectively reduce the noise due to equipment failure aging. Such as: sand work on the belt tensioning belt size should be properly adjusted so that the triangular belt force balance, dual motor drive, the triangular tape on both sides should be grouped matching, try to make the length of both sides consistent.
