    This separation saves a lot in term of pressure drop across the separator as well power consumption. The grits get separated from the fines before reaching LV pockets and rotor (2nd and 3rd phase classification). 2nd phase classification. The second phase classification takes place in LV pockets due to velocity change and needs no energy to do
