Screen rotor
Dynamically balanced multi-foil screen rotor engineered with hydrofoil blade geometry to generate powerful micro-pressure pulses for continuous basket cleaning.
High Performance Screen rotor for All Types of Machines
The Screen Rotor is the dynamic heart of the pressure screening system. Rajiv Machines manufactures precision-engineered screen rotors featuring aerodynamically profiled foils and stepped bump rotors. Every rotor is dynamically balanced to ISO 1940 Grade G1.0 at full operating RPM. As the rotor turns, each foil creates a positive pressure wave that fluidizes the pulp suspension, immediately followed by a negative suction pulse that clears the screen basket slots, preventing fiber stapling and ensuring maximum screening capacity with minimal energy consumption.
Engineered for Superior Performance
ISO G1.0 Dynamic Balancing
Computerized dynamic balancing eliminates vibration and extends bearing and seal life.
Hydrofoil Pulse Generation
Optimized foil curvature generates precise micro-pressure suction pulses for continuous slot clearance.
Hardened Leading Edges
Tungsten carbide / Stellite hardfacing on foil leading edges resists high-velocity erosion.
Energy-Efficient Profile
Streamlined rotor body minimizes rotational drag and lowers electrical power consumption.
