Ultrafine grinding in the installation if the plane and horizontal surface is not parallel will occur vibration, but also when the machine installed plane does not correct, will lead to the machine’s main engine and reducer is not two plane, is also the host of the connection wheel and reducer of the connecting wheel of different hearts. This phenomenon can lead to the operation of the device on the mainframe and the operation of the reducer is not synchronized, resulting in vibration. User two can understand, superfine grinding mainframe operation is driven by the reducer, reducer and host parts of the installation plane is not parallel will cause the machine vibration, making reducer and host parts damaged. In view of this phenomenon, the user can adjust the level surface of superfine grinding.
Ultrafine grinding in the ore milling equipment process will occur normal vibration, but because the ultra-fine grinding is fixed on the ground through the anchor bolts, so its vibration amplitude is very small. However, when the local foot bolts are loosened, the vibration amplitude of the superfine grinding becomes larger, which will cause the parts and materials inside the machine to collide, causing the damage of the machine. In view of this phenomenon, the user only needs to fixed the anchor bolt to be good.
The thickness of the material layer in ultrafine mill is also the two factors that vibrate the machine, when the internal material layer of the machine is too thin, the mill roller and the disc between the gap between the small, prone to impact phenomenon, this impact will lead to the vibration of the machine, the user for this phenomenon needs to increase the amount of feed, thereby increasing the thickness of the material layer.
Vibration occurs when the material is too brittle and the size is too large. At this time because the material is too crisp, easy to break, so it will result in a disc on the two parts of the phenomenon, so that the grinding roller and disc impact, vibration, for this phenomenon, the user to control the size of the feed size, larger chunks of material occurrence of this phenomenon is more likely.
