Raymond mill how to do a good job of dust protection measures
Mill dust emission reason analysis and treatment method:
1. The material itself is dry, in the crushing process will produce a large number of analysis, especially the feed inlet of each device; Solution: can be in the equipment inlet into the atomized dust protection, pay attention to the amount of sprinkler water needs to be strictly controlled, because the Raymond machine on the humidity of the material has obvious requirements, or else conveying pipeline, downcomer, dust collector filter bag will cause clogging phenomenon, the maximum humidity shall not be higher than 6%.
2. The milling production line is a semi-closed structure, open connection at the most dust; solution: you can change the link between the equipment, closed inlet and outlet to prevent dust leakage, such as jawbreaker outlet, silo and other semi-closed composition equipment.
3. There is a lot of dust in the remaining wind emission; Solution: install dust collector, dust collector is very important in the milling production, is now a necessary component of the milling process equipment, dust removal device is directly related to the quality of the entire equipment, consider now the milling equipment based on where? Production capacity, processing capacity, equipment materials, manufacturing process, environmental performance.
4. Improper operation caused by dust leakage; Solution: operate the machine according to normal equipment regulations, especially the fan, feed speed control, material feeding too fast and too much, too much wind will cause serious dust spillage problems.
5. equipment failure problems, wind and dust volume increase; solution: the cause of this dust increase is due to two reasons, one is the machine valve state is not right, in the production line does not form a negative pressure, the mill inlet will have spray powder phenomenon, the second is, the conveying equipment itself has a crack or other reasons lead to poor closure, dust leakage, the above two kinds of need to be based on a different way to find out the reasons for the reasonable adjustment of the milling equipment can be.
