What Is The Bed Depth Of The TSX Vibrating Screen?

Vibrating screen is a common supporting equipment in the sand and gravel production line, which plays a key role in screening various stone powders. The application of different types of shale shakers in the sand and gravel production line is different. Therefore, a good understanding of the types of shale shakers is beneficial to the rational configuration of the production line.

Too large materials will hinder the passage of too small materials, forming a temporary restriction, causing materials to accumulate on the surface of the filter screen (bed).

When the undersized material passes through the wire mesh mesh, the bed depth decreases.

Before discharging at the end of the wire mesh screen surface, the material layer shall not be allowed to reach the depth to prevent the substances under the screen from layering.

In general, when separating 100 pounds per cubic foot of material, the discharge end bed depth should not exceed four times the surface aperture of the wire mesh screen, or three times for 50 pounds per cubic foot of material.

Aggregate, ore and gravel screening formula used to calculate the theoretical discharge end bed depth:

DBD=bed depth at discharge end

O=Oversize in STPH

C=cubic feet per ton of material

5=formula constant

T=Movement speed (nominal movement speed of inclined screen from 18 º to 20 º is 75 fpm, with rotating airflow, and nominal movement speed of horizontal screen is 45 fpm)

W=Width of screening area (feet)

General considerations

It is easy to calculate the bed depth to determine the optimal screen width. If the depth of the bed is too deep, the material will not contact the screen surface. The depth of the fine screen bed is very important, especially when cleaning, to ensure that the sprayed water penetrates the entire depth of the material.  Cohesive, clayey material, UG 2, gypsum requires high-frequency linear horizontal to slightly inclined screens.
