FT - 3400 powder flow behavior (dynamic) analyzer

FT - 3400 powder flow behavior (dynamic) analyzer

Introduction

 By analyzing the dynamic data to describe the flow behavior characterization of powders, powder industry in the processing, storage, transportation, bin often arch/rat hole structure;Such as arch subjected to bin pressure consolidation compression strength increases lead to knot the arch;Woven mesh with each other in the orifice shape arch block material bridge arch;Bonding adhesive arch water, electrostatic adsorption lead to powder with warehouse wall adhesion strength enhance arch;Air pressure balance arch: discharging device sealing is not good, cause a large amount of air leaking from the bottom of the housing material layer caused by upper and lower air pressure balance;In the powder grain storage and transportation system, material, material and material between the liquidity and solid wall friction;In the design of hopper, discharge mouth, hopper wall slope Angle and the size of the powder of hopper wall pressure, unreasonable design of hopper will give production caused great difficulties;These affect the behavior characteristics of powder liquidity can't to solve the traditional measurement methods,The machine by measuring the internal strength, flow function, internal friction function, density function, time, consolidation, wall friction, caking index, quantitative analysis of the dynamic data such as temperature and humidity in the air the above phenomenon and state. Often used in the quality department, research and development new products, improve production technology and formula.

Feature

1 With reference to ASTM_D6128-97;ASTM D66822008  and the 

method analysis of powder flow behavior characterization features, 

using the data model through the automatic control system combined with PC software, through the powder shear, the relationships between time, consolidation stress and the strain yield strength function graph realtime dynamic data collection and analysis, the precompression until the steady flow state. It was applyed in chemical, ceramics processing, food, cosmetics, paint, pharmaceutical, metal powder, graphite powder, plastic, rubber, concrete, and other areas of the powder grain materials quality control and research, often used in production and processing enterprises, research institutes and colleges.
