• Mill spring causes the thickness of the sheet exiting from the rolling mill to be greater than the roll gap set under no-load conditions. • Precise thickness rolling requires the elastic constant of the mill. Calibration curves are needed, see Fig. (1–3 GNm-1 for screw-loaded rolling mills, 4 GNm-1 for hydraulically loaded mills).

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.

Cold rolling takes the hot rolled product and processes it further. After hot rolling, the steel is cooled to room temperature, then passed through cold rollers at a temperature lower than its recrystallisation temperature. This rolling process is called annealing and relieves stress and leads to a higher yield strength and greater hardness.

How the Three Roll Mill Works. The material to be milled is placed between the feed and center rolls. Each adjacent roll rotates at progressively higher speeds. For example; the feed roll may rotate at 30 rpm, the center roll at 90 rpm and the apron roll at 270 rpm. Material is transferred from the center roll to the apron roll by adhesion.
