At the test centre, rock samples can be analysed for crushability, abrasiveness, impact resistance, brittleness and solid density. For product development purposes, the full-scale plant can be used to measure a new device's parameters, such as capacity, product distribution, crushed end-product grading, loads and power consumption.

The problem of cone penetration, particularly deep penetration, remains one of the most challenging in geotechnical engineering. It involves large displacements, rotations and deformation of soil elements in the path of the cone as well as complex response of the soil, including crushing and the development of large mean stresses, to the displacements imposed by the penetration process.
