A monitoring system includes a fastener. A sensor is coupled to the fastener. A circuit board is electrically coupled to the sensor. An antenna electrically coupled to the circuit board.

The present invention provides a system and method for more efficient utilization of comminution mills. Sensors are provided in the liners placed within the mill shell. The sensors may include RFID tags, liner wear profile sensors (e.g., such as an ultrasonic sensor), an inertial sensor (preferably included both an inclinometer and an accelerometer, and an acoustic sensor, among others. When the liners are installed in the shell, the RFID tag is used to register the location of the liner within the shell. In operation, the information provided by the sensors is collected by a data transmission unit and sent by transmitter over the air to a computer having an antenna and receiver for such data. The data is correlated and the data is reviewable in real time while the mill is in running.

A system and method for online estimate of the filling level of balls and loading level in a rotary mills, comprising a set of vibration sensors unit, associated with a magnet to transmit data signals via an antenna to a receiver that receives data signals from the antenna, an antenna, wherein the receiver is connected via optical fiber to a signal processor, which in turn communicates to a control server via a UTP cable, wherein the control server also obtains data from the mill operation to determine the best filling of balls and load; and the operating method.

An apparatus monitors a tumble mill and includes at least two vibration sensors mounted on a first main bearing and at least two vibration sensors mounted on a second main bearing of the mill. Sensors may be disposed radially with respect to the bearing. A vibration sensor is also connected to a thrust bearing of the mill oriented in a direction parallel to the rotational axis of the shell of the mill. A signal analyzer receives and analyzes signals from all vibration monitors on the bearings and displays an operating condition of the tumble mill. Additional vibration sensors may be mounted on the shell, and sensors may be provided to sense electrical power input and mechanical power output of the motors. In operation, the mill is loaded with a standard charge and operated at a standard rotational rate. The sensor data is analyzed and displayed when the mill is operating.
