粉体处理过程中正确掌握粉粒体的流动特性很重要。安息角、压缩度、刮铲角、凝聚度这四种物理性质为粉粒体的流动性指数,而流动性指数、崩溃角、分散度、差角等四项为粉体的喷流性指数,现介绍的是将安息角、压缩度、刮铲角、凝聚度、崩溃角、分散度、差角等七项的粉粒体特性值, It is important to properly understand the flow behavior of the granular material during powder handling. Resting angle, compressibility, spatula angle and cohesion are the fluidity index of the powder and granule, and the fluidity index, collapse angle, dispersion, , Is introduced is the rest, compression, spatula angle, cohesion, collapse angle, dispersion, the difference between the value of the seven characteristics of the powder and granule,
