The numerator is calculating the volume of one swing of a jaw, times the density of material in the chamber, times the number of cycles per minute. This should give you the mass of material crushed per minute. The denominator looks wrong; to convert to mass per hour should be multiplying by 60, not dividing by 60. Dividing by 60 should give mass
