Abstract
A method for separating solid phase from drilling mud, comprising forming from drilling mud an adhesive layer 4 on a revolving closed curvilinear surface 3 by partially submerging it in the drilling mud and forming from a treatment liquid (5) an adhesive layer (7) on another closed curvilinear surface (6) which is caused to rotate in the direction opposite to the rotation direction of the first curvilinear surface (3). Both closed curvilinear surfaces (3, 6) are arranged in such a manner that their adhesive layers (4, 7) penetrate one another at a depth sufficient for the adhesive layer (7) of the treatment liquid to take-off coarse solid phase particles from the adhesive layer (4) of the drilling mud. Linear velocities of the adhesive layers (4, 7) are chosen in such a manner that the resultant centrifugal forces be equal to or lower than the centripetal forces.
