| 摘要 |
The invention is directed to a bulk materials pump and its use. The pump comprises a housing having a flow path for bulk materials located between an inlet and an outlet of said housing, wherein said flow path in said housing is further defined by a space between two rotatable drive disks spaced from each other and wherein a materials scraper is present between said drive disks at the outlet to avoid materials being transported between said drive disks back to the inlet. The rotation axis of both disks are tilted with respect to each other resulting in that the distance between said drive disks at the inlet is greater than the distance between said disks at the outlet. The surfaces of the two drive disks facing the flow path are conical shaped such that at the outlet the two facing surfaces are parallel relative to each other and at the inlet the two surfaces are positioned under an angle relative to each other.
