Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of Flow Properties of Bulk Solids.
Technical Description
The flow properties of a powder or bulk solid determine how it behaves during handling. For example, material may flow irregularly out of silos, or the flow of bulk solid may come to a stop. In order to avoid these problems in practice, silos can be designed on the basis of measurements using shear testers, such as the Jenike shear tester or a ring shear tester.
In a ring shear tester, a bulk sample is contained in a ring-shaped shear cell. A normal force is exerted on the sample by way of a lid. A hanger from which a variable weight is suspended generates this normal force. A motor moves the shear cell relative to the lid in order to apply shear to the sample. For compaction (pre-shearing) the sample is subjected to a large normal force. Electronically amplified force transducers measure the shear forces which are then recorded by data acquisition software over time. After pre-shearing, shearing to failure is executed with a reduced normal force (strength measurement) and likewise recorded by the software. From the shear force characteristics, properties such as the compressive strength and internal friction of the bulk solid can be determined. To determine the density of the bulk solid, the volume of the bulk sample is ascertained by recording the lowering of the lid using a dial gauge. So as to also take into account the influence of the hopper wall material on the outflow behaviour, a separate measurement is performed with a ring-shaped sample of the wall material.
An evaluation software is available to determine the flow properties from the experimental results. The flow properties identified are used to determine the optimum geometry of a silo's discharge hopper. Trainer is provided for practical verification of the design results obtained in terms of mass flow/funnel flow. The ring shear tester and the evaluation software were developed by Prof. Dr. Dietmar Schulze (from Braunschweig/Wolfenbüttel University of Applied Sciences).
