Abstract
An impact detacher with a centrifugal wheel and two or more centrifugal conduits which are enclosed by two or more impact rings, wherein the material to be ground is fed concentrically via a feed pipe and guided away again via an outer annular conduit. Each half of the impact ring is directed to two oppositely directed impact surfaces, wherein the impact detacher can comprise a common product discharge conduit. The centrifugal wheel comprises a guiding apparatus with a divided feed in the area of the product inlet, wherein a larger feed surface is assigned to the centrifugal conduit remote of the feed pipe.
Claims17
An impact detacher for grain-like materials comprising:
- a centrifugal wheel which rotates about an axis;
- the wheel being enclosed within a housing;
- said housing having an annular impact ring;
- a concentric feed pipe for feeding materials to the wheel;
- said centrifugal wheel having a plurality of axially offset centrifugal conduits for the passage of the materials fed to the centrifugal wheel;
- a guiding apparatus being arranged within the centrifugal wheel for delivering the material to the plurality of axially offset centrifugal conduits;
- said annular impact ring including means, having a truncated cone section with two impact surfaces formed by two truncated cones opening in opposite directions, for allowing material passing through two of the plurality of axially offset centrifugal conduits to strike a respective one of said impact surfaces and to change direction resulting in two oppositely directed material streams;
- a product discharge conduit for receiving said material streams for discharging materials;
- and
- a product outlet being provided and associated with said discharge conduit,
- whereby product is discharged from the housing through said conduit and said product outlet.
An impact detacher for grain-like materials comprising:
- a centrifugal wheel which rotates about an axis;
- the wheel being enclosed within a housing, said housing having a plurality of annular impact rings;
- a concentric feed pipe for feeding materials to the wheel;
- said centrifugal wheel having a plurality of axially offset centrifugal conduits for the passage of the materials fed to the centrifugal wheel;
- a guiding apparatus being arranged within the centrifugal wheel for delivering the material to the plurality of axially offset centrifugal conduits;
- each one of said plurality of annular impact rings including means, having at least one truncated cone section with at least one impact surface, for allowing material passing through a respective one of the plurality of axially offset centrifugal conduits to strike a corresponding impact surface and to change direction, said plurality of impact rings being configured such that their impact surfaces direct the impacted material in two opposite directions,
- a product discharge conduit for receiving said material streams for discharging materials;
- and
- a product outlet being provided and associated with said discharge conduit,
- whereby product is discharged from the housing through said conduit and said product outlet.
