Because of this, it is beneficial to introduce the new material to the Dewatering Screen at 50% solids by weight or higher. The lower amount of water in the new feed to the screen will increase the chance of retaining fines on the screen and producing a drier product. Too much water for drainage rate. Drainage rate of the material.

The slot width, or the screen gauge, is sometimes sized to be equal to the formation sand grain size at the 10-percentile point of the sieve analysis. The theory is that because the larger 10% of the sand grains will be stopped by the openings of the screen, the larger sand will stop the remaining 90% of the formation.

When the pressure drop across the sand pack reaches the preset value, the intake valve opens and allows flow directly through the pump intake bypassing the screen. Only at this stage will sand begin to cause wear on the pump, extending the life of the pump by the total operating time during which the intake valve remained closed.

The width of the screen determines the carrying capacity of the screen deck, while the length of the screen determines the overall efficiency of the screen. Typically, the length of the screen is 2.5 to 3 times the size of the width.
