1·The results showed that the friability, abrasion and particles size distribution properties related to microstructure and source of mineral formation of limestone.
结果表明:石灰石的易碎性、 磨蚀性、物料粒度特点与石灰石微观结构及矿物成因有关。
1·RESULTS the different standards of factor are different to the influence level of friability.
结果因素的不同水平对脆碎度的影响程度不同。
2·Objective: To improve its disintegration time limited and friability and make sure the quality of the production.
