This invention consists of a new analyzer system of the sounds generated in mills that capture the signals issued by the mineral and steel balls cascade that perform grinding. These signals are processed in an embedded system (2) formed by a field programmable gates array (FPGA) and a processor. The system is comprised of an industrial microphone array (1) that captures the sound signals that are converted from analog to digital through and acquisition system (3) specialized in sound signals, processed by a FPGA capable of performing parallel operations at high speed due to the customized hardware developed for this application, and sent to the processor through a high-speed data bus.

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 grinding roll including a roll body having a cylindrical outer surface extending axially between a pair of opposite ends and a side groove formed at each end of the roll body. The side groove includes a support shoulder recessed from the cylindrical outer surface and/or from surfaces of the opposite ends of the roll body. The grinding roll includes an edge ring including a plurality of spaced receiving cavities and a plurality of wear members. Each wear member is received and retained in at least one of the receiving cavities of the edge ring. The wear members are positioned along the edge ring to define an edge of the grinding roll, and the edge ring is received within each side groove. The wear members are arranged to provide a wear protecting surface which is angled in relation to the cylindrical outer surface of the roll body. The angled wear protecting surface prevents excessive build-up of material on the grinding roll and reduces the need for maintenance.

A roller crusher having two generally parallel rollers arranged to rotate in opposite directions, towards each other, and separated by a gap, where each roller having two ends. The roller crusher includes a flange attached to at least one of the ends of one of the rollers. The roller crusher further includes at least one mechanical scraper and a remote material removal device configured to output a material removing beam towards a target area. The at least one mechanical scraper and the remote material removal device are arranged consecutive to each other at an end of the roller with a flange for at least partially removing material accumulated on the flange and/or on the outer surface at the end of the roller. A method for operating a roller crusher is also provided.

A method of determining wear of a rotary impact crusher includes adjusting the position of an impact rocker relative to an impact rotor with an actuator by a first adjustment value until a crushing section of the impact rocker contacts an impact bar or an impact circle of the impact rotor. The first adjustment value is compared to a first reference value to make a first comparison corresponding to total wear of the impact rocker and the impact bar. The position of the impact rocker is adjusted relative to the impact rotor by a second adjustment value until the impact rocker contacts a reference measurement section. The second adjustment value is compared to a second reference value to make a comparison corresponding to wear of the impact rocker.

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 process and system for monitoring of wear on components of a grinding mill to determine an optimized future time for maintenance of the grinding mill. The system uses control circuitry for controlling the grinding mill, a sensory system for detecting measurement data on technical parameters relating to a wear condition of a component and an operating state of the grinding mill, analysis circuitry to analyze a wear behavior of the grinding mill, and a data transmitter and data receiver to exchange data. The sensory system detects measurement data on the wear condition of at least one component and the operating state of the grinding mill. The analysis circuitry derives from several pieces of measurement data detected at different times a future wear state at a time in the future and assigns the future wear state to a future degree of wear and a future maintenance loss.

A self-optimizing, adaptive product processing system and a corresponding method for grinding and/or crushing cereals and seeds. The grinding and/or crushing takes place in at least one roller mill which includes a roller pair. So as to detect the temperature of the surfaces of the rollers, at least two temperature sensors are disposed on at least one of the rollers. The detected temperature measurement values are used for optimal adjustment and signal generation of the roller setting.

The invention relates to a method of predicting a level of wear of a wear component of a vertical mill, whereby the vertical mill is used for grinding feed material. The method includes, while the mill is in operation, (i) capturing/obtaining a thermal profile of the mill from outside a grinding chamber of the mill, and (ii) determining an indication as to a level of wear of at least one wear component of the mill which is located inside the grinding chamber, based on the thermal profile of the mill. The step of capturing/obtaining a thermal profile may include performing a thermographic analysis of the mill from outside the grinding chamber of the mill. The determining step may include determining whether the wear component requires changing/replacement based on the thermographic analysis of the mill.

Plate-shaped wear elements for milling means, in particular of agitator mills, having at least one inclined surface area, kits employing them, their uses and methods using them.
