Hammer mills : an engineering overview. What is it ? How it works
The hammer mill design is very robust and is used in many applications, from grain milling to heavy duty requirements such as rock crushing or waste grinding. Hammer mills are part of the impact mill family, which means that the milling effect is obtained thanks to the speed at which particles are impacted, here, by one or several rotors.

energy of crushed kernels (the sum of crushing energy and grinding energy) ranged from 47.6 to 100.5 kJ·kg−1 and from 44.6 to 85.3 kJ·kg−1 for hard and soft wheat, respectively. In addition, the other grinding energy indices confirmed that crushing of kernels prior to hammer mill grinding considerably reduced the grinding energy requirements.
