The Loesche coal grinding mill range is divided into two serial types: Small twin mills constructed to individual specifications (LM 12.2 D to LM 20.2 D), with table diameters from 1,200 to 2,000 mm. Larger mills with two, three and four rollers and modular struc-tures (LM 21.2 D to LM 43.4 D), with table diameters from 2,100 to 4,300 mm.
85% of cast slabs was produced in the USSR at the rolling-mill equipment manufactured at Uralmashplant. Since 1949, Uralmashplant has begun to supply its products abroad. The rolling-mill equipment was supplied to the enterprises of the Western Europe, China, India, Pakistan, Nigeria, North Korea, Egypt, Algeria.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
The shape of the rolling elements depends on the type of load, operating conditions and particular applications. It is the rolling elements that distinguish the two basic bearing categories – ball bearings and roller bearings. There is a groove called the ball path on both the inner and outer races of ball bearings in which the balls roll.
What is a mill file? Shop for Files : Mill files are multipurpose saw files that are most commonly used for sharpening blades. For more information, see: How to sharpen blades with a file : They are also used to even out saw teeth at the beginning of the sharpening process. This has earned them the nickname 'mill saw' files.

Two basic types of roll-forming systems are utilized: a precut line and a postcut line. A precut line shears the incoming material to a specific length prior to roll-forming. During post-cut line operation, the roll formed panel runs continuously and is sheared to the required length after roll-forming.
