Our Stoneless Masa mill produces 2,500 – 6000 lbs/hr of finished masa. The mill is simple to use, dependable and robust. This unit does not use grinding stones & does not require shim stock to establish parallelism between the stationary disc and the rotating disc. The plate life of our mill is rated at approximately 10 million pounds of processed masa before replacement is needed. Rocks, metal, and foreign debris will not destroy the super strong proprietary Nihard alloy plates.
