Breakage Characteristics(破损特性)研究综述
Breakage Characteristics 破损特性 - To study the breakage characteristics of coarse-grained particles under lateral pressure, the breakage characteristics of spherical gypsum particles under three-point contact were studied. [1] In the first step, breakage characteristics of eight samples having different competence were determined by piston-die tests. [2] A mechanistic model for tumbling mills was developed based on breakage characteristics and tumbling mill operational features. [3] The rock macro-breakage characteristics were obtained by describing the breakage patterns, measuring the erosion depth and area, and counting the cracks number. [4] However, the effects of wetting–drying cycles on the breakage characteristics of rock grains still remain unclear. [5] It was observed that when the high voltage pulse breakage (HVP breakage or HVPB) induced cracks inside pre-weakened particles were consumed during impact breakage, the breakage characteristics of the progeny particles are the same to raw ore particles. [6] In this regard, this paper is to apply the discrete element method (DEM) combining bonded particle model (BPM) for simulating impact breakage of rice kernel and revealing its breakage characteristics. [7] The influence of the particle size grade and the confining pressure condition on the deformation and breakage characteristics of the GSW is studied based on large-scale triaxial compression tests in this paper. [8] The modeling technique is based on the mechanical motion equations of the rollers, combined with the breakage characteristics and pressure response of the ore material. [9] In this way, the breakage characteristics (selection and breakage functions) of coal particles are established and the prediction of particle size distribution (PSD) for different levels of energy input is demonstrated. [10] In this work, the breakage characteristics of a copper ore were measured using two batch mills of different designs. [11] It also shows that the shape of load-displacement curves of rocks can be divided into four stages: compaction, elastic, plastic, and fracture, and the curve can accurately represent the transformation and breakage characteristics of rock during shear fracture. [12]为研究粗晶颗粒在侧压作用下的破碎特性，研究了球形石膏颗粒在三点接触下的破碎特性。 [1] 第一步，通过活塞模试验确定了八个具有不同能力的样品的断裂特性。 [2] 基于破碎特性和滚筒磨机的运行特性，开发了滚筒磨机的机械模型。 [3] 通过描述破碎模式、测量侵蚀深度和面积、计算裂缝数量，获得岩石宏观破碎特征。 [4] 然而，干湿循环对岩石颗粒破碎特性的影响仍不清楚。 [5] 观察到，在冲击破碎过程中，当高压脉冲破碎（HVP破碎或HVPB）诱导的预弱化颗粒内部裂纹被消耗时，子代颗粒的破碎特性与原矿颗粒相同。 [6] 对此，本文采用离散元法（DEM）结合键合粒子模型（BPM）模拟稻仁的冲击破碎并揭示其破碎特性。 [7] 本文基于大型三轴压缩试验研究了粒度等级和围压条件对GSW变形和断裂特性的影响。 [8] 该建模技术基于辊子的机械运动方程，结合矿石材料的破碎特性和压力响应。 [9] 通过这种方式，建立了煤颗粒的破碎特性（选择和破碎函数），并证明了不同能量输入水平的粒度分布（PSD）的预测。 [10] 在这项工作中，使用两个不同设计的间歇式研磨机测量了铜矿石的破碎特性。 [11] 还表明，岩石载荷-位移曲线的形状可分为压实、弹性、塑性和断裂四个阶段，该曲线可以准确地表示岩石在剪切断裂过程中的转变和破碎特征。 [12]
Particle Breakage Characteristics
Low-velocity impact responses of typical hollow brittle particles (HBPs) were tested with a strain-limited loading technique to investigate the particle breakage characteristics at both macro and particle levels. [1] The results show that particle gradation, mineral content, blows per layer, and stress level have a significant effect on the particle breakage characteristics of weathered granite soils. [2]使用应变限制加载技术测试了典型空心脆性颗粒 (HBP) 的低速冲击响应，以研究宏观和颗粒水平的颗粒破碎特性。 [1] 结果表明，颗粒级配、矿物含量、层间风量和应力水平对风化花岗岩土的颗粒破碎特性有显着影响。 [2]
