mills, including one mill supported by a non-isolated foundation, were tested on site. Vibration safety was evaluated based on the test results. Furthermore, a mill-foundation coupled finite element model was built using ANSYS to analyze modal and harmonic responses. The calculation results were generally in accordance with the test results.In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in equipment, rolling is done in the ...

Advantages of Roller Mills. 1. Produce more uniform, fewer fines, and oversized particles when it comes to product quality. 2. Generates less heat (0 – 3 0 C) unlike hammer mill that generates up to 10 0 C. 3. Less moisture loss. 4. Better work environment due to low machine noises level.housings (open design) are available for locating bear-ings (design BF) and for floating bearings (design BL). The split housings of series MGO were especially de-veloped for mill applications. They are designed for oil lubrication and feature particularly effective seals.
