  • PRESSURE SCREEN DESIGN | Meston''s Sharing Knowledge

     · PRESSURE SCREEN DESIGN. Pressure screening is nowadays the most widely used method for cleaning pulp, its success being based on the invention of profiled screen plates, which give better capacity per unit screening area than do smooth screen plates (Winkler & Kelly 1994). Pressure screens are also used for the fractionation of pulps, which can ...

  • How to Calculate the Specific Capacity of a Well? | …

    The specific capacity curves are thus constructed as shown in Fig. 5.52. For Q = 1200 1pm, t = 1 year, Q/s w = 199 1pm/m. Therefore, drawdown in the well at the end of 1 year, ADVERTISEMENTS: s w = 1200/199 = 6.03 m. Thus, the specific capacity is a useful concept and indicates the productivity of both aquifer and well in a single parameter.

  • Using Specific Capacity to Monitor Well Performance

     · Specific Capacity can also be used to provide the design pumping rate or maximum yield for the well and to estimate the transmissivity of the surrounding formations penetrated by the well screens. The following equation is used to calculate Specific Capacity: SC = Q/s. Note: SC = Specific Capacity (gpm/ft); Q = discharge (gpm); s = drawdown (ft)

  • What is the Screening Capacity of Vibrating Screen per Area

     · The effective area used to find the capacity of a revolving screen is usually taken to be one-third of the diameter of the drum times the length. The quantity of material that can be handled by a screen during a given time depends on the inclination of the axis and the speed of rotation.


    These screens have large flow capacities and are hydraulically self-cleaning without moving parts, so they require minimal maintenance. Coanda-effect screens have been commercially available for many years in a limited number of configurations.

  • Screening Theory and Practice

    Screening is essentially a volumetric measurement, but capacity, or the rate of passage through the screen, is typically charted in units of weight per unit time, based on a standard bulk density of 100 PCF. The actual rate for a material of different bulk density then has to be adjusted by the ratio PCF:100.

     · For a series of screens of different mesh sizes, the number of openings per unit screen area is proportional to 1/D²pc. The mass of one particle is proportional to D³pc. The capacity of the screen, in mass per unit time, is, then, proportional to (1/ D²pc)D³pc = Dpc Then the capacity of a screen, in mass per unit time, divided by the mesh size should be constant for any specified conditions of operation.
