 The problem is to simulate a screw conveyor with a diameter of 0.2 m and a length of 1 m with a variable pitch. It is filled with 10 mm and 9 mm spherical particles. The timestep for integration is 0.00002 s. Particles are inserted from the top of the feeder at a rate of 2800 particles/s. The number composition of large and small particles is 2:1.
