Spiral pressure recovery blades which can make the rotational flow convert into direct flow in overflow pipe of the cyclone separator are designed in the overflow pipe. The numerical calculation of the cyclone separator with different blades is carried out by using the Reynolds stress turbulence (RSM) model. Meanwhile, the trend of the total pressure of the inlet and outlet of the cyclone separator is discussed while the blades are inserted at different positions. Results show that the pressure of inlet and overflow outlet obviously reduced when the blade is inserted in the cyclone separator. It can make the inlet total pressure reduced more than 9% and the overflow outlet total pressure reduced more than 50% when four blades are inserted in the cyclone separator. The total pressure of the inlet and overflow outlet is the smallest when blades are inserted in the lowest of the overflow pipe.
