Vibration: Vibration is a phenomenon prevalent roller mill work, reasonable and vibration are allowed, but if the vibration is too large, it will cause mechanical damage to the disc and grinding roller and the liner. Therefore, during the operation of the vibration should be strictly controlled within the permissible range (preferably 2.0mm / s or less), to stabilize the operation of the mill. More causes vibration mill, summed up in the following: air flow and air temperature fluctuations; grinding pressure is too high or too low; foreign objects (such as iron) vertical roller mill; material layer is too thin or too thick; storage pressure can be too large or too small; scraper plate wear, multi-product material, uneven distribution of air flow; feed volume fluctuations. Mill vibration control in the production of material may be appropriate to reduce the grinding pressure is reduced and the running while adjusting the water and the circulating air flap, hot air baffle according to the outlet temperature of the material layer thickness and to improve the grinding conditions, when necessary, even through mention the roller to avoid excessive vibration, to be changed for the better after grinding condition, according to the proper pressure feed.
ATOX-50 vertical roller mill has three, each with a set of accumulators. The grinding pressure is produced by the hydraulic system, hydraulic system and three hydraulic cylinders, each hydraulic cylinder are connected with an accumulator, which plays the role of a buffer of hydraulic and pneumatic vibration absorbing mechanical loads during the grinding process.
Three hydraulic cylinder connected to the accumulator when the pumping station can produce research work can be uplifting pressure roller, pressure grinding pressure on the grind size should basically equal, otherwise it will affect the normal operation of the vertical roller mill. Three roller affect performance through rollers and stretching rod with each machine is large, there is a direct relationship with the production. vertical roller mill pressure, abrasive reinforced, high yield; otherwise low yields. But the grinding pressure is not too large, otherwise it will increase the main motor load, increase exercise in futility, while easy to mill vibration intensified, damage mill liners and other devices. When operating, the grinding pressure to keep within a set range. Security protection provided in the hydraulic system oil return valve, when the hydraulic system pressure exceeds the set pressure 7bar, open the oil return valve; When the system pressure falls below the set pressure 4bar when opened hydraulic pump; When the system pressure reaches set when the set value, the pump stops. Also with the size of the grinding pressure accumulator pressure is related to the pressure accumulator buffer is too small or too large will not achieve the damping effect, the relationship between pressure and under normal circumstances the grinding pressure of the accumulator.
