Available for scheduled use. Contact Hui Wang at or (515) 294-3572 for availability.


The Wiley Model 4 Laboratory Mill is a grinder that uses cutting action to comminute its samples. Fed from the hopper, the material drops into the path of four revolving hard-steel knife blades driven at a high speed by an electric motor. The revolving knives work against six stationary knives and the resulting particles are forced through one of three available steel screens (0.5 mm, 1 mm, and 2 mm mesh). The mill is suitable for grinding soft, medium-hard, fibrous and tough materials.
