| 摘要： | IN PREVIOUS RESEARCH EQUIPMENT FOR AUTOMATICALLY DETERMINING PARTICLE SHAPE, BASED ON THE RELATION BETWEEN PARTICLE BREADTH AND PARTICLE THICKNESS, WAS DEVELOPED AND TESTED. SINCE PARTICLE SHAPE SIEVES ARE GRADED IN ACCORDANCE WITH A DECIMAL SERIES (RISING BY 25 PERCENT), A SET OF 15 SIEVES IS SUFFICIENT FOR SEPARATING ALL THE CHIPPINGS INTO THE 5 PRESCRIBED PARTICLE SHAPE GROUPS. THE STUDIES ON PARTICLE SHAPE HAD TO BE LIMITED TO A FEW TYPES OF STONE, BUT EVEN THESE FEW TESTS SHOWED THE SIGNIFICANCE OF DETERMINING PARTICLE SHAPE IN ASSOCIATION WITH THE POSSIBILITY OF SORTING OUT UNSUITABLE PARTICLES DURING PROCESSING. GENERAL INFORMATION OBTAINED ON THE INFLUENCE OF PARTICLE SHAPE HAS TO BE SUPPLEMENTED BY EXTENDED TESTS. SUPERSEDES IRRD RESEARCH PROJECT NO 30915. |
