Hardfacing, also known as hard surfacing, is the application of buildup or wear-resistant weld metals to a part's surface by means of welding or joining. Most worn parts don't fail from a single mode of wear, such as impact, but from a combination of modes, such as abrasion and impact. For example, vertical mill grinding rollers are usually ...

a solution for grinding very fine materials and from it created a new grinding-roller concept – the 2+2 or 3+3 technology, i.e. half the rollers, also called the master rollers, are used for grind-ing. The other rollers, called the support rollers, prepare the grinding bed in order to control the specific properties of the very fine material.
