Loop Jet Mills A further step was taken in the development of the loop jet mill with the goal of improving the sharpness of the "cut" – control of the coarse fraction. Like the spiral jet mill, there are no moving parts in the loop jet mill, and size reduction is a function of particle to particle and particle to wall collisions.
