mill. While reviewing the design of rolling mill components our area of interest is to visit design of rollers and rolling mill housing. We have discussed the different parameters and factors that affect the roll design. The calculations for the power required for rolling operation and the roll dimensions are also discussed.

Chapter 4: Pellet Mill Die and Roll Design die. The dies used in this process are stainless steel or those dies having a high chromium content. Due to the homogeneous hardness throughout these types of dies, they usually offer excellent die life. These types of dies also have a smoother hole surface, resulting in easier start-up.

The aim of this work has been to develop an automatic roll pass design method, capable of minimizing the number of roll passes. The adoption of artificial intelligence technologies, particularly expert systems, and a hybrid model for the surface profile evaluation of rolled bars, has allowed us to model the search for the minimal sequence with a tree path search.
