Pellet Hardness Tester

Achieving Both High-Speed and High-Precision Pellet Hardness Measurement

In the manufacturing process of carbon black, the hardness and size of spherical pellets significantly affect the quality of the final product, including dust generation during transport and dispersibility in rubber or resins. The AS2000-L is a Pellet Hardness Tester that simultaneously measures the hardness and pellet size of spherical samples such as carbon black. It reduces the measurement lead time by about half compared to conventional models (approx. 10 to 15 seconds per piece), contributing to significantly faster quality control.

High-Precision Analysis via Z-Axis Actuator

The greatest feature of the AS2000-L is its extremely high-precision measurement achieved through the adoption of a Z-axis actuator. It can accurately and simultaneously measure both the pellet size and the hardness, which are critical indicators of granulation characteristics.

Support for International Standards and Safety Design

The tester supports measurement conditions for JIS K6219-3, ISO 8942, and ASTM D5230 standards, which can be recalled with a single touch from the dedicated software. Additionally, it features a safety device that allows measurement to start only when the cover is attached, ensuring a safe working environment for the operator.

Dual Data Management Functions

The dedicated software allows you to save and manage two types of data: a pellet size distribution map and individual load curve data (in CSV format). This enables intuitive observation of trends on the PC screen and supports printer output of aggregated data.
