The Art of Milling

To grind moist or even wet sample materials is not possible without both-ersome side effects, especially in jaw crushers, rotor or disc mills. Moist materials tend to block the ring and bottom sieves which can lead to a blockage of the machine. As a conse-quence, material is lost and much time and effort has to be spent on cleaning the mill.
