A dynamic separator for pulverulent materials, such as cement, lime or raw materials, comprising: a primary rotor which can rotate about a vertical axis and is provided with primary selection blades arranged about its periphery in such a way as to sweep a hollow circular cylinder during the rotation of the primary rotor, a secondary rotor provided with secondary selection blades arranged around its periphery, and guide valves located on the outside of the aforementioned cylinder such as to form a primary selection chamber between the guide valves and the primary selection blades. At least part of the secondary selection blades is located inside the cylinder, such as to form a secondary selection chamber between the primary selection blades and the secondary selection blades. A separation method using a separator is also disclosed. |

1. A dynamic separator for pulverulent materials, such as cement, lime or raw materials, comprising a primary rotor able to rotate about a vertical axis, provided with primary selection blades arranged at its periphery so that as the primary rotor rotates they sweep a hollow circular cylinder, a secondary rotor provided with secondary selection blades arranged at its periphery some of said secondary: selection blades being situated inside said cylinder so as to form a secondary selection chamber between said primary selection blades and said secondary selection blades, and guide vanes situated outside said cylinder so as to form a primary selection chamber between said guide vanes and said primary selection blades, characterized in that said secondary selection blades and said guide vanes protrude beyond the bottom of said cylinder so as to form, under said cylinder, between said guide vanes and said secondary selection blades, as tails selection chamber intended to cause the tails coming from the primary and secondary selection chambers to undergo an additional separation operation.
