The prototype developed proposes a granulometry (P80) measurement system for rocks in mining conveyor belts without interrupting the operation and optimizing the use of electronic equipment for its operation. Currently there are similar commercial options that require a considerable investment of money and space for the complete solution both in the field and in the computer server room. Small mining operations that cannot afford these requirements choose to use the manual method that requires to stop the process to obtain rock samples and then transport them to a geotechnical laboratory that provides a value of P80 with which operational decisions can be made. In addition to the economic impact of stopping the process, the results arrive untimely and could cause errors in operational decisions. The developed prototype implements a camera, controlled lighting and the use of image processing algorithms executed on a single-board computer. The samples are obtained by the camera and the images are processed with segmentation algorithms such as the watershed and a sequence of morphological transformations of erosion and dilation to obtain the sizes of the identified rocks. Finally, the Rosin-Rammler linearization model is used to obtain the value of P80 and present it on an interactive touch screen within the operator's reach. The results obtained with this prototype have an accuracy of 89% with respect to the results issued by a geotechnical laboratory and a success rate of 91.3%.
