To pick a machine for grinding material - granite, RM=3300кг/m3 is the density of the material; pH = 2000 kg/m3 - bulk density of the material; σсж=350МПа - the ultimate strength of the material under compression; E = 7•104МПа is the modulus of elasticity of the material; G=80T/h - mass performance; δНМАХ=0.8 m - maximum size of pieces of the source material; δКМАХ=80•10-6m - maximum final particle size.
