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. |
