The at least one sensor being carried by the liner body to sense wear of the wear surface side of the liner body. The at least one sensor being configured to degrade in response to wear of the wear surface side of the liner body and to output a signal representative of the wear of the wear surface side of the liner body.

A measuring device for ascertaining the temperature of a roller surface of a roller body is insertable into a recess of the roller body and includes at least first and second temperature sensors, a mounting rod on which the sensors are situated in the axial direction of the mounting rod spaced apart from each another, and, on each side of each respective one of the temperature sensor in the axial direction a respective supporting element arranged on the mounting rod. Between the supporting elements, the mounting rod is flexible such that each of the temperature sensors is able to be pressed onto an inner wall of the recess with a defined contact force.

A pulverizer for reducing a size of input material particles having a housing, a rotatable shaft with rotor arms and at least one airflow deflector cooperating with the rotor arms to deflect airflow within the pulverizer so as to form at least two overlapping vortices within the interior chamber such that input material particles in suspension in both overlapping vortices collide with each other to be thereby pulverized. The pulverizer also having a housing liner including a plurality of housing liner portions attached to and extending along a outer structural wall of the housing. The pulverizer also having a housing sidewall having an outer structural wall with a plurality of wall sections. The pulverizer also having canted rotor arms and rotor arms with removable wear pads. An anti-caking device for a vessel such as a pulverizer is also provided.

A device and a system monitor wear of wearable components mounted in a mining equipment. An elongated bolt maintains a wearable component in place on a face of the equipment. A threaded section of the bolt terminates at a proximal end protruding externally through a hole of the equipment. A shank of the bolt terminates at a distal end opposite from the proximal end. The shank extends along a thickness of the wearable component and wears as the wearable component wears when the equipment is in operation. A transducer coupled to the proximal end of the bolt generates a sound wave within the bolt, detects an echo of the sound wave reflected by the distal end of the bolt, and reports to a controller a time delay between the sound wave and the echo. The controller evaluates a wear of the wearable component based on the time delay.

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.

The invention relates to a system that enables real-time monitoring of wear and tear occurring in rubber liners and lifter bars used in the internal structure of the ore grinding mills employed in the mining sector, in addition to obtaining estimations as to the replacement times of worn parts.
