During rotation of the wheel the material is transported between a higher and a lower position so that the torque caused by the material on the wheel is recorded and used for determn. of the transported material weight. The wheel blades have a constant clearance between them and the wheel axis, and the material leaves them within an angle between plus or minus 10 degrees around the vertical line through the wheel rotation axis. - The wheel speed is maintained constant, but when a given torque value is exceeded, it rotates more rapidly than the speed of free fall of the material. |
