COMBINED PRESSURE AND MILLING PUMP

Combined pressure milling pump consists of the pump (4) and the mill. The mill consists of at least one stator (2) and at least two rotors (3), both said stator (2) and said rotor (3) being fitted with passage holes (1, 6) and said rotor (3) being mounted on the shaft (8), which passes through the entire arrangement. The longitudinal axes of said retarding passages holes (1) of said stator (2) of the mill are inclined in a negative angle of 0 minutes up to 75 degrees with respect to said shaft (8), and the longitudinal axes of said accelerating passage holes (6) of said rotor (3) are inclined in a positive angle of 0 minutes up to 75 degrees with respect to said shaft (8). The area of said retarding passage hole (1) of said stator (2) and, subsequently in the discontinuous streaming direction, the area of said accelerating passage hole (6) of said rotor (3) or the area of said accelerating passage hole (6) of said rotor (3) and, subsequently in the discontinuous streaming direction, the area of said retarding passage hole (1) of said stator (2) always decrease in accordance with the ratio 1:2. In the discontinuous streaming direction, the sum of areas of passage holes (1, 6) increases from 0 to 100 percent and the distances (5) between said stator (2) and said rotor (3) always change in the decreasing ratio one to one tenth.
