总结：雷蒙磨是一种低速研磨设备，雷蒙磨主机的转速一般在150-260转/分钟范围内。

在长期工作的情况下

雷蒙磨 是一种低速磨粉设备，雷蒙磨主机的转速通常在150-260转/分钟范围内。
 
在长期工作情况下，雷蒙磨粉机的磨室会产生一定的温度，但由于雷蒙磨的转速较低以及雷蒙磨风扇的冷却，雷蒙磨磨室的温度通常可维持在50摄氏度。
 
How to solve the high temperature problem of 雷蒙磨 grinding chamber, the 雷蒙磨 temperature is mainly caused by the friction heat generated during the material crushing process. Because the 雷蒙磨 wind selection system uses the circulating air system, the heat dissipation problem is The use of 雷蒙德磨机 is particularly important during the use of the Raymond 磨粉 Roller assembly and the properties of the material being processed (materials that are required for temperature). The main method to solve the 雷蒙磨 temperature is to use a better dust removal method. For example, a pulse dust collector is used. The pulse dust collector has good gas permeability, small dust, and automatic dust cleaning function, and can timely discharge high temperature air in the mill. Inhalation of room temperature air in order to reduce the temperature of the Raymond grinding chamber.
