A supply tube assembly has a central longitudinal axis, a first end and a second end and includes a supply pipe extending in parallel with the central longitudinal axis from the second end of the supply tube assembly to the first end of the supply tube assembly. The supply pipe is open to form a pipe outlet at the first end. The supply pipe is configured for transporting solid particles carried by a fluid from the second end to the pipe outlet. A ramp arranged inside the supply pipe at the pipe outlet and pivotably arranged such that the inclination of the ramp in relation to the longitudinal axis is adjustable by pivoting the ramp about a pivot axis which is perpendicular to the central longitudinal axis, with the ramp extending from said pivot axis towards the pipe outlet. |
