• The Working Principle of Hammer Mills (Step-by-step Guide)

    The Working Principle of Hammer Mills (Step-by-step Guide) A hammer mill is an essential machine in the pharmaceutical and food processing industries. You can use it to crush pulverize shred grind and reduce material to suitable sizes. Even though there are many types of hammer mills the working principle is still the same.

    Lastly a study comparing the statistical particle size distribution parameters was performed for process design purposes. It was deduced that if the desired particle size is greater the comil provides a narrower particle size distributions than the hammer mill whereas if the desired particle size is smaller both mills exhibit similar poly-dispersity.
