Two common problems in the operation of powder sprayers

Two common problems in the operation of the powder spraying machine
The vibration of the powder spraying machine is large
The reason is that the material feeding is easy to be unstable during the initial start-up, and the control of large and small times is not smooth, causing the material level on the grinding plate to be low. It is not easy to produce vibration.
If hard foreign matter enters the grinder, it will cause sudden vibration. Iron removal should be strictly implemented.
. The blanking point is not on one side, which may cause periodic vibrations. The blanking point should be improved and the material should be fed from the center of the grinding plate
. The particle size changes are too large and the size changes frequently, causing the grinding roller to Vibration, the appropriate feeding particle size should be controlled
, the material flow is unstable, the feeding is sometimes large and sometimes small, and the water content is sometimes large and sometimes small, making it difficult to adapt to the rolling air distribution, causing the grinding roller to jump
and the material layer is too large Thin materials are dry and fine-grained, causing the thrown materials to form no material layer, the buffer is too small, and the vibration is violent. The material flow resistance should be improved
, the material layer gradually becomes thinner, the air material is unbalanced, the ventilation is small, the slag is spitted out more, the circulating material is less, the material pressure is unbalanced, the material is large and the pressure is small, the grinding efficiency is reduced, the slag is spitted out more and the circulation Less material. These will cause the material layer to slowly become thinner and cause vibration. The improvement measures are to adjust the appropriate process parameters
If the hydraulic system is too rigid, the accumulator charging pressure can be appropriately reduced.
The hydraulic system applies pressure to the grinding roller
The thickness of the coal on the grinding plate is related to the vibration. The thickness of the coal seam can only cause the pressure difference of the powder sprayer to increase and the coal mill to be overloaded. If it is not reduced in time, Feeding materials and increasing circulating air volume will eventually lead to high pressure difference and tripping
