Strong Raymond, Raymond Guangxi, Gezhi machinery

Because there are still Improved Raymond roller mill ring problems, although a slight increase in the roll diameter, but not grinding force increases. Later, the US subsidiary Combustion Engineering of Raymond and on this basis, developed a new generation of powerful Raymond Raymond, called VR mill. In many respects this Raymond Loesche mill structure similarities. It is worth noting that it is different from Loesche grinding tapered roller and flat disc, while using a cylindrical roller and grinding disc surface tilt angle of 15 degrees with use. Roller has in the inspection and maintenance and Loesche roller mill similar device pulls Nanjing Raymond, and also fitted with a protective device to prevent metal contact between the roller and the disc. Also before starting the roller mill can be lifted ahead of time, so you can reduce the starting torque of the motor. Raymond industrial applications in the United States, usually used to prepare coal, changes in product fineness between 250-325 mesh Raymond, adjustable work product fineness and yield during operation. Raymond mill hardness and Mohs hardness: Because it is destructive test, so the unground of the original stone or precious of minerals can be used. There are two types of hardness scales, one is the absolute hardness, and the other is a Mohs hardness (a relatively hardness). Mohs hardness: Ten to common mineral used as a standard by scratching each other hard to distinguish what what soft Chongqing Raymond, customary on mineralogy or gemology is Mohs hardness. Mohs hardness ten minutes. Talc, gypsum, calcite, fluorite, apatite, feldspar, quartz, topaz, corundum, diamond. Head is a general characterization of pore size sieve, the conversion formula is: cm = 16 / number of projects have English and American, British refers to the number of holes per square inch.
