Raymond mill is a low-speed grinding equipment, and the Raymond mill main engine speed is generally in the range of 150-260 rpm.
 
In the case of long-term operation, the Raymond grinding chamber will generate a certain temperature. However, due to the mill’s low speed and fan cooling, the chamber temperature will not exceed 50°C.
 
How to solve high temperature problem of Raymond mill grinding chamber, the Raymond mill temperature is mainly caused by the friction heat generated during the material crushing process. Because the Raymond mill's air classification system uses a circulating air system, heat dissipation becomes particularly important during operation — especially in relation to the grinding roller assembly and the properties of the material being processed (particularly for materials that are sensitive to temperature). The main method to solve the Raymond mill 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.
