 H.E.L SAS

 

The H.E.L. Limited Subsieve AutoSizer (SAS) is a new addition to the established field of air-permeability particle sizing. It has been developed as a direct and improved successor to the widely used Fisher Model 95 Sub-Sieve Sizer (FSSS). The SAS adds automated functions, and electronically recorded and presented data, to an established particle sizing technique. The SAS uses the principle of pressure drop across a packed bed of powder. By varying the sample height, and hence the “porosity” of the bed, average surface area and particle size can be determined as a function of pressure drop in accordance with the Carmen equation. The SAS measures particle size in the range of 0.2 µm to 75 µm and has a compression accuracy of less than 0.05 mm.

 MA-1040 Magnetic Analyzer

 
   The MA-1040 Magnetic Analyzerdetects and measures low levels of metallic iron content in sample materials. Whether it be ultra high-purity glass used in the manufacture of fiber optics or plastic used to produce insulation for electrical wires, knowing the concentration of metallic iron in the raw material is critical to controlling the quality of the finished product.Particulate Systems’ MA-1040 Magnetic Analyzer incorporates modern electronics and features 0.1 parts-per-million (ppm) resolution, a wide dynamic range, and low power consumption. Other improvements include reduced mechanical pick-up (microphonics) and mu-metal shielding of the sensing coils.

SPECTester Material Segregation Tester

 
 

SPECTester Applications

 

 SPECTesterMaterial Segregation Tester – Using state-of-the-art spectroscopic technology, the innovative SPECTester is capable of analyzing a sample comprised of up to six individual components and provides a simple report indicating why and how much the sample material is segregating. Fully automated, the instrument provides data about component concentrations, particle size differences, and product uniformity.Most manufactured products today are mixtures of several components. Generally, the individual ingredients in a mixture will separate (segregate) during the manufacturing process which results in an inconsistent final product. Segregation, or separation, of granular powder materials is one of the main causes of process failure with systems that handle powder materials. Conservative estimates suggest up to 30% of all unscheduled downtimes are due to segregation and quality issues.Key features of the SPECTester include:

  • Measurement of mixtures with up to six components
  • Fully-automated operation with reports of how much as well as why the material mixture is segregating
  • Touch screen / keypad control
  • Provides component concentrations, particle size differences, and product uniformity
  • Identifies primary segregation mechanism out of four specific types
  • 50 segregation points measured across the sample bed
  • Segregation identified by particle size, sifting, fluidization, angle of repose, chemical component, and air entrapment
  • Identifies process design parameters and quality control issues
  • Provides uniformity index for sample and segregation variance data
  • Data can be exported to Excel® format
  • Fast analysis – 10 to 30 minutes to complete a run depending on the sample and application
  • CE compliant

 SSSpinTester

 
   From the perspective of material characterization, the yield strength of a powdered material can be defined as the stress or force required to fracture a pre-compacted consolidated mass of material to initialize flow. Therefore, when determining the flowability characteristics of powdered or granular materials, the yield strength is very important. The sample material will flow as long as the force acting upon the sample to cause the flow of the material is higher than the sample’s yield strength value. This information can be used to determine the flow factor of the material.The SSSpinTester uses the science of centrifugal force to measure the unconfined yield strength of fine powders using a sample amount as small as 60 mg. The instrument provides this data by first consolidating the material using centrifugal force to compress the sample inside the sample holder. After the initial compaction step, the SSSpinTesterthen completes the analysis routine using the same centrifugal force to determine the yield strength of the material. Using the latest advancements in technology, this instrument provides measurements at forces in a range from as low as 0.05 kPa to as high as 72 kPa. This extended pressure range provides actual performance results without the need to extrapolate data leading to inaccurate results. This automated instrument provides repeatable and consistent results. SSSpinTester Features
