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.

1. The reason for poor performance of rolls was partly operational and partly manufacturing. Since the mill is semi-automatic, a strict discipline on the part of the operating crew is needed for improving the roll life. 2. From the performance data, the major cause of failure of indigenous rolls was spalling.

Rolling is the most important metal forming process. More than 95% of ferrous and non-ferrous metals and alloys are processed to their usable shapes by rolling. Usable shapes of rolled metals are plate, sheet, strip, foil, different sections like rail, beam, channel, angle, bar, rod, and seamless pipe, etc., as shown in Fig. 1.1 and Fig. 1.2.

4.2.3.1.1 Roll Mills. The roll mill is the simplest batch mixing equipment. The principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds. The ratio of the peripheral speeds of the rolls, known as friction ratio, ranges from 1 to 2 but is usually around 1.2.

2.1 Experimental set up. A Hille-100 rolling mill with rolls of 225 mm diameter and 254 mm length, driven by a variable speed DC motor of 75 horse power, was used. The maximum rolling force, torque and speed are 1500kN, 13kN-m and 70 rpm respectively. The sensor roll nitrided surface hardness is 65 to 70 HRC. The diameter of the top and bottom ...
