Jul 19, 2009· hi friends, I have a problem regarding the hardfacing of roll table liners and wear segments of MPS vertical roller mills. The mill is being used for grinding of limestone mainly at a rate of 215 tonnes per hour. I would be thankful if anyone can tell me which type (composition) of hardfacing to use to reduce the wear rate. It will be of great help if the information regarding the company that ...
If roll wear can be reduced, roll cost is directly reduced. The indirect cost for roll turning, grinding and maintenance will be decreased as well. On the other hand, wear of the roll directly influences the dimensional and shape accuracy of products, which influences the strip production to a much higher degree. Therefore it is very important
1. High efficiency: roller compacted materials directly onto the grinding disc, so power consumption is low. Compared with ball mill, it saves energy consumption by 30% ~ 40%. 2. Less wear and tear: As the roller is not in direct contact with the disc, and material of the roller .
Type of Wear — The primary consideration in selecting the final hardfacing layers is the type of wear to be encountered in service. These include: a. MetaltoMetal Friction — Wear from steel parts rolling or sliding against each other with little or no lubrication. b. Severe Impact — Wear from severe pounding which tends to squash ...
