This paper presents a theoretical study of the motion of a cotton piece in a screw cleaner and the impact forces
generated during its interaction with screw spikes and a mesh surface. The impact impulse is analyzed as a function of the
initial velocity of the cotton piece, the rotational speed of the screw, and the tilt angle of the spikes. Theoretical calculations
show that at a screw rotational speed of 180 rpm and a spike tilt angle of α₁ = 8°, the impact impulse reaches its minimum
value. An increase in the impact force leads to a higher number of broken seeds in seed cotton. In addition, the proposed
screw cleaner combines the cleaning and drying processes, which contributes to an increase in the overall operational
efficiency of the equipment.
