**When vibrating screen screening materials with a weight of 1.6t/m, the allowable depth of the bed shall not exceed 5 times of the screen, and when screening materials with a weight of 0.8t/m, the allowable depth of the bed shall not exceed four times of the screen hole.**

**In general, attention should be paid to:**

**The following formula is often used to calculate the capacity of vibrating screen**

**The total formula is: VSC=D * W * V * C**

**VSC is the capacity of vibrating screen**

**D is the depth of the riverbed**

**Recommended depth calculation of movable screen to determine * the best screen width.**

**B If the vibrating screen is too deep, the material will not contact the screen surface.**

**C The depth of fine screening is very important, especially when washing, to ensure that the sprayed water penetrates the entire depth of the material.**

**D One third of the screen will allow 80% of the material to pass. The balance is used to take near sized materials to provide 95% efficiency.**

**E Viscous, clayey material, UG 2, gypsum requires high-frequency linear horizontal to slightly sloping screens.**

**After that, all the parameters needed to calculate the material flow on the screen are obtained. Now, the velocity can be easily calculated by the formula defined below.**

All of these calculation steps are provided as an example, and all of the values used here are selected randomly. The same calculation step may be followed in calculations, or the sort of calculation may be changed, depend on exact values you have. All operations discussed here are invertible that’s mean, if the flow rate is already known, or if a specific flow rate is needed, the material velocity, vibromotor operating speed or the stroke of the system may be calculated easily in the same way.The above is about how to calculate the capacity of vibrating screen.
