The release of particles from bulk materials is usually an undesired quality. Nevertheless, it can occur in a wide range of material‐handling processes and may present a hazard to humans and the environment. Therefore, the dust formation tendency represents an important material property that depends on the specific type of stress. A forecast of the dust formation tendency could simplify and expedite the assessment of possible hazard potentials as it would eliminate the need for comprehensive dustiness measurements. A single‐drop method was used to analyze the dustiness of nine materials at low pressure conditions. Based on the experimental results, an empirically derived apparatus‐specific forecast parameter and a prediction function were developed.

单滴设备中低真空条件下散装物料粉尘的预测公式

从散装材料中释放颗粒通常是不希望的。但是，它可能发生在各种材料处理过程中，并可能对人类和环境造成危害。因此，粉尘的形成趋势代表了一种重要的材料特性，该特性取决于特定的应力类型。对粉尘形成趋势的预测可以简化并加快对潜在危害可能性的评估，因为它将消除对全面粉尘测量的需求。使用单滴法分析了九种材料在低压条件下的粉尘。根据实验结果，开发了根据经验得出的设备特定的预测参数和预测函数。
