The adoption of high-pressure grinding technology over the last 25 years has led to significant energy savings as well as reduced costs for wear material. But the conventional welded rolls used predominantly today in high-pressure grinding roller presses (HPGRs) are subject to rapid and excessive wear.
Badly cracked, deformed or work hardened surfaces should be removed by grinding, machining or carbon-arc gouging. 3. DEPOSIT THICKNESS Avoid excessive build-up of hardfacing deposits or they may crack and break off rapidly in service. If thick deposits are needed, use the appropriate build-up materials before hardfacing. 4.
4. Segmented wear parts for grinding table and rollers allow use of the most wear-resistant materials and hardfacing process for long life. 5. Reversible roller segments ensure high material utilization. 6. External circulation limits power consumption of fan. 7.

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.
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 ...

Roller press is a highly efficient communication system where the feed material is exposed under a very high grinding pressure between two solid rollers [ one fixed and one moving ] for a short time due to compression. The high pressure causes formation of micro cracks in the feed material and generates a substantial amount of the fine material.
Grinding is a machining process improving the surface finish of the job and producing small chips. The tool used for this process is the grinding wheel. It is a cutting tool in which millions of microscopic abrasive grains are bond together. Here, each abrasive grain acts like a spiky tool. As shown in the image, the abrasive grains are held ...
