Rolling of Steel in a Modern Long Product Rolling Mill
· Long product is a common name for (i) reinforcement steel bars, (ii) shaped steel bar products such as rounds, flats, squares, and hexagon etc., (iii) sectional products such as angles (equal and unequal), channels, beams, tees, and special profiles etc., and (iv) wire rods. Mills which roll long products are known as long product mills.
WhatsAppOptions for Grinding Slag and Pozzolan for Use as Construction ...
Vertical Roller Mills have gaining more popularity in new projects due to possible 40% less energy consumption than ball mills. 9. For materials such as slag and pozzolan which are received as fine materials <5mm for slag and between 10mm and 50mm for pozzolan, the VRM requires lower power consumption. 5.

If the gate is adjusted automatically, it will be slaved to the amperage load of the main motor of the roller mill. The rolls that make up a pair will be 9 to 12 inches (23 to cm) in diameter, and their ratio of length to diameter can be as great as 4:1. It is very important to maintain the alignment between the roll pairs.
