High-wheat feeds are very water-stable if properly steam conditioned before compression and extrusion in a pellet mill. Feeds low in, starch require a thick ring die and extra steam for conditioning. Special binders of starch origin provide some degree of water stability for pellets made with low-starch formulae.

– Find distribution of roll pressure – Calculate roll separation force ("rolling force") and torque – Processing Limits – Calculate rolling power. Prof. Ramesh Singh, Notes by Dr. Singh/ Dr. Colton 13 Flat Rolling Analysis • Consider rolling of a flat plate in a 2-high rolling mill

The multi-stand plug mill (MPM) with controlled (constrained) floating mandrel bar and the plug mill process in the size range from approx. 140 to 406 mm outside diameter. The cross roll piercing and pilger rolling process in the size range from approx. 250 to 660 mm outside diameter.

Large amounts of mill scale also cause severe pitting corrosion if the surface is in contact with water. Scale on the surface is usually removed mechanically, using water under high pressure or acid pickling and then oiling to reduce rusting.

•High friction results in high rolling load, a steep friction hill and great tendency for edge cracking. •The friction varies from point to point along the contact arc of the roll. However it is very difficult to measure this variation in µµµµ, all theory of rolling are forced to assume a constant coefficient of friction .

the mill retains the stability and accuracy of the roll gap and imposed pressure. The castings absorb the high pressures and shock loads to give a long and trouble free life • A high precision, rigid bearing arrangement, enables the production of very fine flakes, if required • Chilled iron rolls manufactured from
