DEVICE FOR PRODUCING A POURABLE PRODUCT AND METHOD FOR USING SAID DEVICE

摘要

The invention relates to a device consisting of a rotor chamber (1) in which a rotor (4) having a vertical rotor axis (3) is arranged, where the rotor (4) at least along its radial outer third has the shape of a conical envelope (22), and guide vanes(11) for circulating the starting material or product. The guide vanes (11) are arranged above the plane (9) of the upper edge (5) of the rotor (1) and statically against the inner wall (6) of the rotor chamber (1). Their cross-section in relation to the rotor axis (3) substantially has the shape of a segment of a circle or spiral and their inner ends are situated approximately in the central part of the rotor radius. The conical envelope (22) can have at least partly flat gas passages in the shape of holes or screens. The invention also relates to the use of the device for the production of pourable products. According to said method, cores are prepared or a coating layer is deposited on cores.
