Hydraulic Crusher for Concrete Breaking
Noise reduction for some mitigation measures for reference. Use of hydraulic concrete crusher is much quieter than using hydraulic breaker in demolition projects. The operation principle of hydraulic breaker is by percussive striking actions of its chisels, so that much more noise would be generated as compared with hydraulic crusher.Noise levels L eq in dB(A) Gyratory crusher (view point of crusher top on the side) 96.4: C3C belt drive (feed to scalper B) 96.1: C3C belt drive (feed to scalper B) 96.1: Scalper B: (Tables 2.2.1 and 2.2.2) showed direct impact noise of coal and rock on steel to be the single and most common source of noise.Health risk of exposure to noise in coal preparation and mineral

Vibration Diagnosis of Sand Units in a Stone Crusher Plant: An
Due to the shortage of natural sand from rivers and seas, artificial sand production from large stones or rocks is being increased. However, this sand manufacturing process is dangerous and causes several social problems such as a high level of unwanted vibrations or noises. This study investigates the vibration characteristics of sand and Based on the characteristics of mining noise and surface rock crushing (Pathak et al., 1999; Roy and Adhikari, 2007; Scott et al., 2010;Saha and Padhy, 2011) and on the continuous operation miningSound level on different floors of the crusher house.
