5. The biggest danger of the filter press to the human body is the high-pressure state at work, that is, the oil cylinder burst. The incidence is very low, only one in ten million. It is OK to stand less in front of the oil cylinder when working. The other is that the coal procts are dirty, and the st in the filter press post is very little. If you go to a place where the filter press has a high degree of automation, the actual operation will be very labor-saving, It may be dirty when replacing the consumption parts of the filter press.
