Fully automatic measurement of particle hardness!
The Micro Hardness Tester MHT-1 is an automatic compression testing device designed for fine particles ranging from 40 to 400μm, achieved by changing the measurement stage. It measures the peak load and particle size when a load is applied with a punch to crush the particles, determining the crushing strength. The process from compression to destruction is recorded with image data and load-displacement curves. By selecting any particle from the measurement results, the destruction process can be confirmed with the load-displacement curve and continuous images. Thanks to our unique technology, each particle is dispersed and automatically sampled. The measurement is automated, repeating the compression test and cleaning simply by loading the sample. *Depending on specifications, the target particle size may be 40 to 120μm or 50 to 400μm. For measuring particles ranging from 200 to 1500μm, the Better Hardness Tester BHT-1000 (fully automatic powder and granular compression testing device) is available.

Detailed information
-
Particles are fed into the hopper for sample input. After that, simply issuing a measurement command from the software will automatically complete the sampling and measurement process.
-
The samples loaded into the hopper are dispersed onto the stage. Equipped with our proprietary automatic sampling mechanism, it is possible to place even fine particle samples onto the measurement stage one by one.
-
Using our particle shape image analysis software technology, we distinguish whether the sampled particles are primary particles or agglomerated particles. By excluding agglomerated particles from the measurements and accurately measuring primary particles, we enhance the reliability of the data.
-
The recognized measurement particles are crushed in order, and their strength is measured. A load cell is built into the bottom, so it detects the load when the particles are pressed down with a measuring indenter from above.
-
After the compression test, the load cell and the particle installation stage are automatically cleaned with a cleaning brush, and the sampling process is repeated automatically.

Company information
To create high-quality products, powder technology is an essential foundational technology. Since our establishment in 1968, we have consistently strived to acquire high-level powder technology. In particular, our contract processing division has become our mainstay, having cultivated extensive experience and achievements. We have responded to a wide range of customer requests, handling the processing of many materials and refining various processing techniques such as crushing, classification, mixing, drying, coating, and compounding. The fine powder products developed using the processing technologies gained from our extensive contract processing experience are our original offerings. These products utilize our unique chemical grinding technology, enabling us to achieve a level of grinding that cannot be obtained through other grinding methods, as well as allowing for special processing such as compounding with inorganic materials, compounding between resins, and surface coating.
