    12/10/2019& 0183;& 32;Abstract. Short impact load cell SILC tests provide insight on the dynamic breakage behaviour of rocks. The measured impact force to first fracture of a rock specimen is used to calculate properties such as fracture toughness, tensile strength, and stiffness. To explore the repeatability and performance of the SILC test and verify the underlying Author: Karina Barbosa, Rick Chalaturnyk, Benjamin Bonfils, Joan Esterle, Zhongwei Chen

    Experimental Study on Limestone Cohesive Particle Model …

    The speed of the limestone particles before impact can be calculated from the pictures taken by the high-speed camera. The aggregated particles can also be collected efficiently after crushing. The crushed particles are collected and processed by a combination of mechanical screening and image processing to calculate the mass distribution and the true crush ratio of the particle size interval.Author: Huaiying Fang, Dawei Xing, Jianhong Yang, Fulin Liu, Junlong Chen, Jiansheng Li
