粉体流动行为分析仪(静态力学)剪切法

  

FT-3400粉体流动行为分析仪

FT-3400 Powder flow behavior analyzer

1. 描述:Description

通过分析粉体剪切动态数据来描述流动行为表征,粉体工业在加工、存储、运输、料仓中常出现拱架/鼠孔结构;如压缩拱受料仓压力作用固结强度增加导致结拱;锲形拱块状物料互相啮合在孔口架桥成拱;粘结粘附拱水分、静电吸附导致粉料与仓壁粘附力增强成拱;气压平衡拱:卸料装置密封不好,导致大量空气从底部漏入仓内使料层上下气压平衡所致;在粉粒料的贮存与输送系统中,物料的流动性、物料之间及物料与固体壁面的摩擦;在料斗的设计中,排料口的大小、料斗壁的倾斜角以及粉料对料斗壁的压力,设计不合理的料斗会给生产造成很大的困难;这些影响粉体流动性的行为特征无法采用传统的测量方法来解决;本机通过测量粉体内部强度、流动函数、内部摩擦函数、密度、时间固结函数、壁面摩擦函数、粘结指数、温湿度等动态数据定量分析上述现象和状态

The flow behavior characterization was described by analyzing the powder shear dynamic data, The powder  arch/rat hole structure is common during the process of processing, storage, transportation, and SiloSuch as compression arch subjected to bin pressure consolidation strength increase lead to knot the arch, The clam shape arch material meshes with each other in the arch of the aperture form arch.The adhesion arch adhere to moisture and electrostatic adsorption cause the powder and the silo wall adhesion to enhance the arch.Air pressure balance arch: the discharge device is not well sealed, causing a large amount of air to leak from the bottom into the chamber and make the upper and lower aire pressue balance.In the storage and delivery system of the powdery and granular materials, the flow of material, Friction between material and material and solid wall;In the design of hopper, The size of the discharge opening, hopper wall slope Angle andThe pressure of the powder to the wall, unreasonable design of hopper  caused great difficulties in production;The behavior characteristics that affect the liquidity of the powders cannot be solved by traditional measures.This machine by measuring the internal strength, flow function, internal friction function, density function, Time consolidation function, wall friction, caking index, dynamic data such as temperature and humidity in the air ,quantitative analysis the above phenomenon and state.
二、功能描述Functional description

参照ASTM_D6128-97ASTM D6682-2008Jenike方法分析粉体流动行为表征特性,通过粉体剪切、固结、时间应力与应变关系屈服强度函数实时动态数据采集和分析曲线图,预压缩直至稳态流动状态. 建立莫尔圆破坏包络线、流动因子、有效内摩擦角、屈服轨迹线、流动函数、Jenike流动性指数FI判断流与不流及临界点、计算料斗半顶角、粉体空隙率、松装与压实变化关系、.采用PC软件建立及分析数据模型,通过对粉体流动函数FF、内摩擦函数、壁面摩擦函数、松装密度及开放屈服强度的测量来分析粉体的表征。

Refer to ASTM D6128-97; ASTM D6682-2008 and Jenike method to analyze powder flow behavior characteristics, Through the powder shear, Consolidation, the relationships between Time stress and the strain yield strength function graph real-time dynamic data collection and analysis , Pre-compression until the steady flow state. Establish Mohr circle destroys the envelope, flow factor, the effective internal friction Angle, The yield line and flow function, the Jenike liquidity index FI judging flow and no flow critical point, calculation of hopper half-apex Angle, powder void fraction, apparent and compaction change relationship, Precompression until steady flow state. Adopt PC software to establish and analyze data model, Analyze the characterization of powders by measurement of powder flow function FF, internal friction function, wall friction function, apparent density and open yield strength.
