Powder Tester PT-X
The Hosokawa Micron Powder Characteristics Tester called as “Powder Tester” is measuring instrument for the indexes of the “Flowability & Floodability” of dry powder. They were defined by Mr. R.L. Carr (Carr Index) to measure 10 individual powder characteristics, such as angle of repose, cohesion, bulk density and to calculate using with Carr’s index table. Mr. Carr (American mining engineer) has measured more than 1000 powder samples to complete the Carr’s Index Table.
Principle of Operation
Measurable characteristics
Bulk density and related values
Aerated Bulk Density, Taped (Packed) Bulk Density. Compressibility
Angles
Angle of Repose, Angle of Spatula, Angle of Fall and Angle of Difference.
Others
Cohesion or Uniformity and Dispersibility
Options
Equilibrium tapped bulk density
It is measured manually till the packed volume converges within the set value.
PSD measurement (JIS compatible)
Gives the diameter of d10, d50, d60 and d90 respectively by sieving. The unit can be mounted with maximum 12 stages of sieve drums.
Automatical measurement of tapped density based on USP, JP, ASTM and Kawakita’s method
The unit can measure automatically the tapped density with graduated measuring cylinder (USP, United states of Pharmacopoeia). This unit can also supply the others measuring methods of tapped bulk density, such as based on JP (Japanese Pharmacopoeia), ASTM (America Society for Testing and Materials) and Kawakita’s evaluation method. This unit can automatically monitor the powder volume by image analysis and the charging continues till the preset point.
Features
Easy operation
Operator friendly monitor instruction and the improved parts design. Total operation time is shortened to 77% compared to the previous model (For this model, total 20 minutes to complete all the analysis.)
No individual operator’s error by following operating instruction shown on the PC monitor 5 languages are available, Japanese, English, German, Chinese, or Korean (All overseas languages are available as option). The operating software has new functions such as CSV output of the data, controlling the access level to the data, etc. to satisfy the customer’s requests.
High accuracy and reproducibility
Fully redesigned the moving parts such as vibration and tapping parts give high accuracy. PT-X minimizes a personal error such as measurement of angle or falling motion by shocker. Storage of every measuring condition repeats to set the same condition as the past.
Dedusting function
PT-X is designed for air tight structure to prevent a leakage of dust. For the dusty powders, vacuum cleaner can be connected to the PT-X to aspirate the ambient. Optional manual sampling feeder helps to feed the material without opening the enclosure while operating.
Measurement of small volume sample
Optional small table for measurement of angle of repose and bulk density cup can apply for small volume sample.
Statistical analysis software (equipment supplied since 2018/12)
Dedicated statistical analysis software(equipment supplied since 2018/12)
It is possible to easily analysis by only reading measured results obtained by PT=X is available without high level kwnoledge.
Following three values can be easily obtained by this software.
1. Representative values of data ( Average, Standard deviation)
2. Difference between data (Statistical significance test)
3. Relationship between data (Correlation coefficients)
