总结：在矿石磨加工行业中，雷蒙磨适合于对超过400种材料如石灰石进行细粉加工，

在矿石磨加工行业中， 雷蒙磨 适用于加工石灰石、方解石、膨润土、高岭土、白云石、煤、粉煤灰等400多种物料的细粉加工，但很多用户会问雷蒙磨粉机把物料加工到多少细度？

磨机的材料精度也是一样的。一般来说，它可以在50-325目之间调节，部分材料可加工到400目。如果需要细致的细粉，应该选择我们公司的超细磨。但是，雷蒙磨在加工细粉时有一个特殊的特点，例如细度高和产量低，高细度和高产量。雷蒙磨有多款 YGM 系列设备，每个型号的细度相同，但产量和功率不同，设备尺寸也不同。设备型号的选择可以根据自己的资金、电源和实际使用情况进行选择。没有必要选择越大越好的型号，越好的型号越具性价比，并且还有与雷蒙磨相匹配的设备。如果有条件，可以配备自动给料设备。如果没有条件，可以选择人工给料的方法。

The main effect of Raymond mill processing materials is that the grinding roller is crushed and then air-selected. When processing ore and other materials, the grinding roller and the grinding ring will wear more. Some friends buy Raymond mill when they purchase it. I will ask how long the grinding roller and the grinding ring can be used. The length of this time is related to the material properties of the processing and the time of production. Some friends are processing bluestone, and they do not need to change for 8 hours a day. 磨粉 rolls and grinding rings. Some friends who work on bauxite also work 8 hours a day. They need to change the grinding roller and the grinding ring in a month or two. Even the grinding roller and the grinding ring with wear-resistant materials can not be used for too long. The toughness of the material is not easy to be powdered, the processing yield is low, the sand iron of the material is relatively strong, and the grinding roller and the grinding ring are relatively comparative. Therefore, the processing of different materials, the operation life of the grinding roller at different times is not necessarily the same.
