There is a certain difference between the design speed and actual use speed of the Raymond mill. The rotation speed of the small Raymond mill is about 280-220 rpm, the rotation speed of the medium-sized Raymond mill is about 140-180 rpm, and the rotation speed of the large Raymond mill is about 60-120 rpm.
The rotation speed of the Raymond mill is directly related to the output and performance of the Raymond mill. The grinding capacity indicators of the Raymond mill mainly have three items: the rotation speed of the central axis of the Raymond mill, the quality of the Raymond grinding roller, and the centrifugal radius of the Raymond grinding roller. The rotation speed of the central shaft is directly related to the use efficiency of the Raymond mill. The same Raymond mill may have different output due to the rotation speed of the central shaft of the Raymond mill. In the process of using the Raymond mill, some customers install their own inverters to easily control the spindle speed of the Raymond mill. Grinding light materials (or small materials) can reduce the speed of the Raymond mill because of this The grinding capacity of Raymond Mill is sufficient, and the reduction of speed is to save power consumption and noise of the machine. If it is heavy material (or massive hard material), it is necessary to increase the rotation speed of the central axis of the Raymond mill, thereby increasing the centrifugal force, increasing the grinding capacity, and increasing the output rate of the Raymond mill.
