Abrasive Test Machine (LCPC)
The abrasive nature of rock is an important factor when designing appropriate testing machinery. The impact on tool wear much depends on the machinery used for excavation. This includes all devices and tools that come
into contact with the material being excavated. The most technical way to determine rock abrasivity is to use an index laboratory test as well as LCPC.
The LCPC abrasivity testing device is based on the French standard P18-579 and has been developed by the “Laboratoire Central des Ponts et Chausées” (LCPC).
The main principal behind the LCPC abrasivity coefficient is to measure the weight loss of a steel plate rotating at 4500 rpm for 5 minutes in 500 gr of rock previously crushed to pieces of between 4 to 6.3 mm in diameter. This steel (metal) plate has a Rockwell hardness of 60-75 HRB.
The ratio of the plate’s weight loss to the mass of tested material is defined as the abrasivity coefficient (ABR) in terms of gram per ton.
