Raymond mill is widely used in milling companies, and its high efficiency, energy saving, stability and reliability have been recognized by users. The wind system in the Raymond mill powder selection system is very important and has a large impact on production and quality. If the phenomenon of residual wind is unfavorable for normal production, the most experienced Raymond mill manufacturers will explain the problem.
Why is there a residual wind in the production process of Raymond Mill? Here are four answers:
1. During the feeding process, the materials are relatively loose, which is related to the material itself. The air between the materials will bring residual wind as it enters the Raymond mill.
2. During the production period of Raymond mill, a certain amount of heat will be generated during the operation of the province. The internal temperature will be nearly 30 degrees higher than the outside, and the material will be dried to some extent. The internal water will evaporate to produce water vapor. This led to the creation of the wind
3. The temperature of the body fluid rises, and the whole fluid expands due to the temperature increase.
4. One section of the inner ring of Raymond mill is under negative pressure. When the feeding port, maintenance door, discharge port, large cyclone separator and nozzle are not tightly sealed, residual wind will also be generated.
As can be seen from the above four points, the Raymond mill in the production process, the system air volume will inevitably increase. At this point, it can be seen that the total capacity is constant, and the residual wind will cause the internal pressure to rise, which is certain. At the same time, it leads to the quality and output of Raymond milled products. At this time, the excess air volume should be removed by the residual air duct. At this time, the bag filter should be used to remove dust after dust removal.
