ball mill working under negative pressure

GPC

How Is Negative Pressure Involved With Breathing? , According to Louisiana State University Medical School, negative pressure in the lungs relative to the surrounding air pressure is what causes inhalation during breathing. This is accomplished by increasing the volume of the lungs, which decreases the pressure until new air passes through the trachea to equalize it.Read more≫
