· In the piston and die test, the breakage energy is measured and the data is then used for calibrating the energy model. This paper aims to show how the particle size distribution and the energy model is modelled for a Sandvik Hydrocone crusher using the work by Evertsson, 2000, Lindqvist, 2005, see Fig. 1.

Dry the Sample in an Oven. The drying process is a very important step because the weight will be the key indicator for creating the aggregate sieve analysis. Moisture in the material adds weight falsifying the results. Reweigh the Sample. This is your reference weight to check if your screening results add up. Split the sample evenly.
