The mill type MEX is designed for grinding of dry and free flowing products as well as for fat containing or high protein products, and also for high fibers.

The MEX series comprises of four sizes and a range between 132 and 355 kW for the drive, and an automated screen change.

Eight screens fitted in frames can be combined without exchanging sieves to optimize the grist spectrum of your product.
