MONITORING DEVICE FOR ROLLER CRUSHER Russian patent published in 2018 - IPC B02C25/00 B02C4/00 

FIELD: physics.

SUBSTANCE: group of inventions relates to means for monitoring devices for crushing materials, as well as a high-pressure roller crusher and a sorting device in which a monitoring device is used, and a method for monitoring the roll surface of a roller crusher. Group of inventions can be used in the mining industry. Monitoring device for monitoring the roll surface of a roller crusher comprises a light emitter arranged to project a line on the surface of the roll, an image capturing device arranged to capture an image of a portion of the surface, the portion including at least a part of the projected line, and a processor unit arranged to process the image to determine information about the surface, said surface information being used to detect a defect or the absence of wear-resistant pins, detect defect or missing edge blocks, and/or detect defect or missing flanges. High-pressure roller crusher comprises two rolls and at least one said monitoring device. Sorting device comprises two rolls and at least one said monitoring device. Method for monitoring the roll surface of a roller crusher comprises projecting a line of light on the surface of said roll, capturing an image of a portion of said surface, said portion including at least a part of said projected line, and processing said image to determine information about said surface. Information about said surface is used to detect a defect or the absence of wear-resistant pins, detect defect or missing edge blocks, and/or detect defect or missing flanges.

EFFECT: group of inventions improves the quality of monitoring.
