cutter mill is a size reduction equipment consisting of a series of uniformly spaced knives (2 to 12 in number) attached to a horizontal rotor (rotating knives) which act against a series of stationary knives attached to the mill casing. the bottom of the mill has a screen attached to control the residence time of the particles inside the mill
all uni-mill models provide excellent versatility as they come with customisable and interchangeable tooling, allowing operators to change the screen hole size, screen hole shape and impeller type. it is therefore possible to use the same mill for multiple products and various applications, including dry and wet milling. alongside pharma milling applications, our equipment is a proven
