Grinding foreign matter
Metal foreign matter is hard because of its texture, so when the grinding roller grinds it, the impact and damage to the liner are more serious. At the same time, the grinding roller will also produce large beating, causing sudden vibration. Although the grinding material passes through several iron removing devices, the protective device that falls off in the grinding, the large piece of the liner will still cause large vibration.
The belt is called broken material, out of control, and the fluctuation is large.
Due to changes in seasons and materials, the belt is said to have broken material and jamming. Especially when limestone and sandstone are broken, the material layer will suddenly become thinner, the buffering effect will be weakened, and the grinding pressure will still be relatively large, causing vibration. . When the belt is said to be out of control and flying, the grinding material is abnormally increased, causing the material layer to be too thick and the grinding effect to be reduced. At the same time, due to the large amount of materials, the pressure difference becomes large, and the ventilation is not smooth. When a certain limit is reached, the Fly Ash Grinding Mill will suddenly vibrate suddenly, and when the feed fluctuation is large, the wave form of the material layer will be formed, and the grinding roller will undulate on the grinding disc. Uncertain, causing vibration.
The layer is too thin or too thick
The material layer is actually a cushion pad sandwiched between the grinding roller and the grinding disc. Under normal circumstances, the grinding roller and the pressing of the grinding disc on the material are the extrusion of the material in the material layer. When the material layer is too thin, the buffering effect is too large, resulting in a decrease in the grinding ability, a decrease in the production capacity, and a pressure difference gradually rising. When a certain limit is reached, the vibration suddenly increases. Therefore, in normal operation, the thickness of the layer should be closely monitored, and the parameters should be adjusted in time to stabilize the layer within a certain range.
