Introduction The Electronic Ear type PI 213 is a magnetic Sensor also know as Sound Transmitter, which is using the mill shell as Membrane. This means the Sensor is only detecting the mill shell vibrations, caused by the Grinding balls hitting the mill lining and material in the mill, and so the Pyrotech Noise Level Sound Transmitter system is insensitive to foreign acoustic noise from other ...Introduction The Electronic Ear type PI 213 is a magnetic Sensor also know as Sound Transmitter, which is using the mill shell as Membrane.Fig.1 . The ball mill A structure borne sound sensor is attached directly on the shell of the rotating mill. It acquires all sounds which occur in the metal wall. Noise and sounds produced by other mills or machines are completely ignored by this sensor, as it is totally insensitive to airborne sound.Oct 08, 2019 Introduction. The ball mill is indispensable grinding equipment in the ore beneficiation process.How to control the ball mill noise Ball mill is mainly used for grinding materials in the industrial production process.The ball mills are also operated in a closed circuit employing two hydrocyclone separators. controlled via a primary variable from a sound measuring system consisting of an array of A magnetic boom is used to trigger the reference sensor on the mill every rotation of the mill.Large ball mills are used in the extraction of copper from large boulders. These mills sound, alerting workers to add oil to the bearing tray to avoid burn out. planning on expanding the use of this sensor to other ball mill applications in the future. Figure 2.
