Solid Bowl Centrifuge without flocculant addition -SBCsim

1. Select the machine size from the drop-down menu.

2. Manually change SBC dimensions and operational parameters, if needed.

3. Select feed solids parameter from the drop-down menu. We provide five examples as for your reference.

4. Solids density can be approximated using the following formula: Solids density can be approximated using the following formula: [1300 kg/m³ x (1-ash)] + [2500 kg/m³ x ash]

5. PSD can be changed manually from the table; hit the "Display PSD" button if you want to compare PSD with the provided examples.

6. PSD can also be estimated from D₅₀ and D₈₀; select Cumulative Passing and input the appropriate numbers. Hit the "Generate PSD" button to update the PSD in the table.

7. Hit "Run Simulation" button at the bottom of the page
