  • Development of low noise and vibration tunneling

    However, the crushing capacity of the rock fracturing method is less powerful than blasting, and crushing with one free face is impossible. In other words, although cracks are caused at the working face by some methods, it is difficult to cause large cracks when only one free face is formed. Two or more free faces enable to secure rock-moving spaces and to make cracks larger. Therefore, it is

  • Several Methods of Reducing Noise of Rock Crushing

    Several Methods of Reducing Noise of Rock Crushing Equipment. Noise generated by stone crushing equipment in operation is unavoidable. It will cause great harm to people's health and living environment. Since there is no way to avoid noise, we can only work hard in reducing noise.
