O-SEPA high efficiency separator is the third generation of efficient dynamic separator, it has been widely used in cement grinding system of the enterprise, the improved O-SEPA is selected powder in the original O-SEPA machine basis, adopts the most advanced technology, high efficiency separator developed. Technical characteristics: 1 rotor blades, special shape, so that the powder selecting machine sorting area is enlarged, the separation rate of material in the actual circumstances of the higher, the powder selecting effect is better; 2, the internal rotor powder machine increases the slipstream scattering device has the following advantages: A) to avoid the drop slip generated, reducing the pressure drop of the powder selecting machine; B) the air flow generated by the rotation of the energy to the rotor, reduce electricity driving device, while avoiding the slipstream generated energy; C) selected export powder machine at the tangential velocity due to the use of the slipstream scattering device and reduced, and reduced wear. 3, increased three times the air, so that the powder selecting efficiency can reach above 80%; 4, choose the product particle size distribution is more uniform, particle distribution more reasonable, thus very high specific surface area. Technical parameters:
