豆奶粉粉體流變儀的概念
豆奶粉粉體流變儀的概念
一.功能描述Functional description：
通過分析粉體剪切動態數據來描述流動行為表征，粉體工業在加工、存儲、運輸、料倉中常出現拱架/鼠孔結構；物料之間及物料與固體壁面的摩擦；在料斗的設計中，排料口的大小、料斗壁的傾斜角以及粉料對料斗壁的壓力，設計不合理的料斗會給生產造成很大的困難；這些影響粉體流動性的行為特征通過測量粉體內部強度、流動函數、摩擦函數、密度、時間函數等數據分析上述現象和狀態. 采用PC軟件建立數據模型實時分析.
The flow behavior characterization is described by analyzing the powder shear dynamic data. The powder industry often has arch/rat hole structure in processing, storage, transportation ａnd silo; friction between materials ａnd materials ａnd solid wall; in hopper design In the middle, the size of the discharge opening, the inclination angle of the hopper wall, ａnd the pressure of the powder on the hopper wall, the irrationally designed hopper will cause great difficulty in production; these behavioral characteristics affecting the fluidity of the powder are measured by measuring the inside of the powder. Strength, flow function, friction function, density, time function ａnd other data analysis of the above phenomena ａnd states. Real-time analysis of data models using PC software.
