Patent number: 11458481Abstract: An apparatus including a rotor position detection unit with a sensor configured to detect an angular position of a rotor of a horizontal shaft impact crusher, the rotor having attached thereon a group of hammers. A motor control system is configured to change the rotation speed of the rotor and an automation and control system is configured to control the motor control system in response to the detected angular position of the rotor. The rotor position detection unit is configured to detect a first and second angular position of the rotor corresponding to a first and second position of a hammer of the group of hammers attached to the rotor. The motor control system comprises a frequency converter and a brake configured to enable the stopping of the rotor.Type: GrantFiled: February 5, 2020Date of Patent: October 4, 2022Assignee: Metso Minerals, Inc.Inventor: Marko Salonen

Patent number: 10710088Abstract: A gyratory or cone crusher includes a measuring apparatus suitable for measuring load of the crusher, a first element placed on a main shaft of the crusher and a first detector suitable for detecting the first element which first detector provides a trigger starting a measurement revolution, and at least one second element placed on a drive shaft of the crusher and a second detector suitable for detecting the second element and providing a trigger corresponding to a certain rotational position of an inner blade of the crusher. The system includes an output to a screen for presenting the loads or averages of the loads corresponding to rotational positions of the inner blade of the crusher. Detections of the monitoring system can be used for controlling and monitoring a crushing event, such as by changing an area or a location of a feed opening of the crusher.Type: GrantFiled: April 11, 2013Date of Patent: July 14, 2020Assignee: Metso Minerals, Inc.Inventor: Marko Salonen

Patent number: 10589289Abstract: A method for controlling the operation of a crusher, a mineral material processing plant and a control system. The method including measuring a quantity related to stress to which the crusher is exposed during the crushing of material, determining a deviation value of the quantity related to stress, comparing the determined deviation value to a reference deviation value, and in response to the deviation value differing from the reference deviation value, adjusting a default setting of the quantity related to stress.Type: GrantFiled: March 18, 2014Date of Patent: March 17, 2020Assignee: Metso Minerals, Inc.Inventors: Jouni Mahonen, Jouni Rahkomaa, Marko Salonen

Patent number: 9937500Abstract: A jaw crusher including a body, a fixed jaw, a shaft which is arranged horizontally and in direction of a crushing surface of the fixed jaw, and a pitman which is eccentrically movable in relation to the shaft, wherein an electric motor is arranged between the pitman and the shaft. A mineral material processing plant. A method for driving a jaw crusher including a body, a fixed jaw, a shaft which is arranged horizontally and in direction of a crushing surface of the fixed jaw, and a pitman which is forming a crushing chamber with the fixed jaw, the method including moving the shaft eccentrically in relation to the pitman, the method further including the steps of arranging an electric motor between the pitman and the shaft and rotating the shaft by the electric motor.Type: GrantFiled: January 3, 2012Date of Patent: April 10, 2018Assignee: Metso Minerals, Inc.Inventors: Risto Sutti, Jari Jonkka, Marko Salonen
