LCPC Test Device

The LCPC (Laboratoire Central des Ponts et Chauss°es) test device is a laboratory equipment designed to evaluate the abrasiveness of soil, rock, and granular materials. This test determines the abrasiveness coefficient (ABR), playing a crucial role in the performance analysis of tunnel boring machines (TBM), drilling, and excavation equipment, which are exposed to high abrasion.

Working Principle :

During the test :

• The steel test plate (60-75 Rockwell B hardness) rotates at 4500 RPM for 5 minutes, interacting with a 500-gram sample (4-6.3 mm particle size).
• Once the test is completed, the mass loss of the steel plate is measured to calculate the abrasiveness coefficient (ABR – g/t).
• The ABR value is a key parameter for predicting the performance and wear resistance of cutting tools and excavation machinery.

• High-speed abrasiveness testing at 4500 RPM
• Steel test plate (60-75 Rockwell B hardness)
• Full compliance with AFNOR P18-579 standards
• Optimized sample chamber for accurate test results
• Emergency stop button for safe operation
• Robust steel body resistant to impacts
• User-friendly digital control panel
• Compact and efficient design for laboratory testing
