APPARATUS AND METHOD FOR ANALYSIS OF SIZE, FORM AND ANGULARITY AND FOR COMPOSITIONAL ANALYSIS OF MINERAL AND ROCK PARTICLES

摘要

Equipment and process for three-dimensional measurement of size and shape andfor compositional analysis of mineral and rock particles and the like objects.A mixture of particles or objects of same or different sizes of minerals orrocks or the like are fed individually and automatically onto a conveyor beltfor three-dimensional machine vision measurements using laser and two camerasand subsequently for spectroscopic measurements using visible and infraredlight and are then collected at the end of the conveyor. Computer software isused to perform the measurement automatically and to calculate size, form,roundness, and preferably petrographic composition and other characteristicsor properties of each individual object and the statistical distribution ofrelevant properties, either according to built-in measurement processes oruser specific methods.
