Differential pressure control. Description. In these applications the control valve will open and close to maintain a set differential pressure between two points. Advantages: A constant differential steam pressure is maintained in the system. The differential pressure ensures that condensate is actively purged from the heat exchange system. This is particularly important where accumulated ...
differential pressure across the mill drum and to regulate the acoustic signal of the mill. But all those systems could not ensure the maximum possible grinding productivity and they did not prevent a possible blockage of the mill. The maximum possible grinding productivity depends on the properties of the solid material (grain composition, grinding ability index, rock concentration, Fig. 1 ...

The differential pressure control can be modified to measure the pressure drop across an orifice and the control converted to a volume control. A velocity across the inner labyrinth of 5 fps would be considered sufficient to prevent backdiffusion. This arrangement does have the advantage of reducing the seal gas requirement. For a practical design, the velocity should be increased to at least ...
be exactly controlled. In the first group this might be 70 °C (160 °F) and rise then slowly to 105 °C (220 °F) in the later groups at the dry end. Results In the dryer the incoming steam turns partly to condensate. The differential pressure over the dryer is the main figure in the system design. This must be maintained to evacuate the condensate in a proper manner and amount. The ...
