10  General Category / iShutdown troubles and solutions / Vertical roller mill and the quality of the material to mutiny on: June 02, 2015, 08:32:57 AM
How to distinguish the quality of the material quality, roller is the core of the vertical roller mill, the quality of these parts will affect the level of machine quality. Generally speaking, the market of the grinding roller made of ordinary steel, high manganese steel casting, a variety of different materials.
Customers don't know how to distinguish between different material mill rolls during the purchase, because different material can seriously affect the service life of the machine.. I can give you a variety of different materials to the roller.
First, quality the is of general material, the service life of the ordinary materials also have one of the shortest, this is very common, use a magnet to absorb about, will be adsorbed on the top and the material of the grinding roller is the worst.
Again, it is the alloy, this is more common. Some of the alloy companies use is hollow, this can weigh, to judge the material is not hollow vertical roller mill. The hollow certainly won't be too durable.
Then, is the high manganese steel, the material is the most durable. The material of the grinding roller, generally with magnet, is not a reaction, using these methods can mutiny grinding roll material, high quality, good and bad.
