Cerchar Index Device is a testing device used to determine the abrasive properties of rocks and natural stones. This device is indispensable for material analysis, especially in the field of mining and rock mechanics.
- Cerchar Abrasion Index (CAI): The device determines the abrasive properties of rocks with the Cerchar Abrasion Index (CAI) value.
- According to the ASTM D7625-22 Standard Test Method for Laboratory Determination of Abrasiveness of Rock Using the CERCHAR Abrasiveness Index Method.
- This index is described also in accordance with the article published in the International Journal of Rock Mechanics and Mining Sciences, numbered 40(2003), pages 259-263.
- Scratch Tips: The device is equipped with 20 scribe tips with 55-56 HRC hardness and Ø 10 x 100 mm dimensions. These scratching tips create scratches on the surfaces of rocks by applying a certain force, and the abrasiveness of the material is evaluated through these scratches.
The Cerchar Index Device is the ideal tool for measuring the abrasive potential of rocks and natural stones reliably and precisely. This device provides high accuracy and reliability when performing material characterization and analysis in laboratory environments.
