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 screen units in an artificial sand …

2014-12-23 · Vibration Isolation Vibrations are produced in machines that have unbalanced masses. These vibrations will be transmitted to the foundation upon which the machines are installed (see Fig. 1). This is usu-ally undesirable. To diminish the transmitted forces, machines are usually mounted on springs or dampers as seen in Fig. 2, or on some other ...
