About adjusting method of Raymond mill automatic feeder

During the operation of the raymond mill, there is a certain error in the manual feeding method, which can not guarantee the uniform feeding of the material, and it is easy to cause the phenomenon of material blocking or idling in the grinding chamber of the equipment host. The electromagnetic vibration feeding device replaces the manual feeding method, realizes continuous and uniform feeding, and avoids the disadvantages of manual feeding. Today, I will introduce the adjustment method of Raymond mill automatic feeder here. 1. During the operation of Raymond mill, the automatic feeding system will be realized automatically, which is mainly realized by the motor and current. When the Raymond mill is running normally, the main machine current will exceed the rated current, it will automatically stop feeding, and when the current drops to the specified range, it will automatically feed. The feeding method is to open and connect the control voltage through the current relay. 2. During the operation of the Raymond mill, the automatic feeding starts. It is necessary to dial the main of the control cabinet to the automatic device, and gradually increase the potentiometer on the control cabinet to make the value reach a certain range and keep stable. status. At the same time, adjust according to the rated current of the host, change the current of the relay, and open the closed contact when it rises. 3. When the current drops, it should be closed in time, so that the Raymond mill can maintain a good working condition, so that it does not cause the phenomenon of empty grinding or overload, and ensure the benefits of equipment milling。
