As a large-scale equipment, the noise produced by Raymond grinding mill is unavoidable, but if the sound of equipment running is too large, it will also do some harm to the life of operators and the surrounding residents. It's also called noise pollution. In fact, the noise produced in the operation of mine equipment can be reduced by certain measures. This article takes the superfine raymond powder mill equipment of the mineral processing equipment as an example to explain.

Ultrafine Raymond mill equipment is commonly used in chemical industry, metallurgy and mining industry. The noise generated by 95dB (A) can reach 120dB (A) during production. It is one of the most powerful noises in industrial production, so it must be controlled.

Which methods can reduce the noise produced during the operation of the superfine raymond mill machine equipment? The study found that there are three main methods to reasonably control the noise, they are installing sound insulation cover, sound insulation and soft sound insulation curtain isolation.

1. sound insulation cover
The sound insulation cover is the cover of the whole superfine raymond mill equipment, and the sound absorption body is added to the hood in order to eliminate the reverberation noise. This method usually obtains the noise reduction effect of 25-45dB, but it can not effectively isolate the noise from the ultra-fine raymond mill equipment to the outside world. The common sound insulation cover has two kinds of fixed and active type. Some superfine Raymond mill equipment manufacturers will be equipped with sound insulation cover randomly, but because the volume of ultrafine Raymond mill equipment is too large, this measure is poor ventilation and heat dissipation, and machine maintenance is not convenient, so it is seldom used.

2. Sound insulation
As an improvement of the method of sound insulation, sound insulation has been widely applied to control the noise of ultrafine Raymond Mill in recent years. It solves the problem of insufficient maintenance and repair space, but there is still a problem of poor ventilation and heat dissipation.

3. soft sound insulation curtain
Soft sound insulation curtain is a kind of sound insulation equipment developed, it uses soft elastic acoustic fiber materials, absorbing and insulation made of louver curtain, which has good ventilation and daylighting properties and high soft removable and simple and convenient use, especially suitable for limited space of the superfine Raymond mill equipment noise control place. This new type of noise control soft sound insulation curtain is gradually replacing the traditional rigid insulation structure, widely used in ultrafine powder Raymond mill equipment in operation.
