In the use of concrete mixing plant, we can adopt the whole station closed design, add the isolation board, isolation room and other measures for the concrete mixing plant, and adopt the closed design to reduce noise emission. [caption id="attachment_2433" align="alignnone" width="300"] Cement Plant[/caption] In addition, the main noise source concrete mixing plant is mixing console, for mechanical equipment, the main problem with noise is mutual fit precision machinery itself, to improve their production level and technology level, improve the manufacturing precision of the position such as host, tanks, the processing technology of a set of feasible and perfect solution, minimize the equipment with a clearance, especially the host in the mixing drum of lining board of the blades and spacing as narrow as possible, prevent sticking stone shrill voice.
